Description: Hi HN!

Super proud to showcase Foqos! I wanted to create a way to physically block apps on my phone, always had a bunch of NFC tags, combined the 2 together over the holiday break and Foqos was born. You can create profiles, write them to NFC tags and track your weekly focus.

Its completely open source and will always be free! There is an affiliate link in the app for nfc tags and donations are completely optional

2. Show HN: Printercow – Turn any thermal printer into an API endpoint

Show HN: Printercow – Turn any thermal printer into an API endpoint - Project Screenshot

URL: https://www.printercow.com/

Author: lionpixel

Description: I've always been fascinated by thermal printers – there's something magical about seeing text and images materialize on paper in seconds. But I found that working with them programmatically was always a pain. You either had to deal with ancient printer protocols or use clunky vendor-specific SDKs. So I built Printercow (https://printercow.com) – it turns any thermal printer into an HTTP endpoint with just one command.

Technical details:

  • Supports any ESC/POS compatible printer (Epson, Star Micronics, etc.)
  • Handles paper widths from 58mm to 120mm
  • Automatic image dithering and scaling
  • Built-in failover protection for high-volume scenarios

    Don't have a printer yet but want to try it out? I've got you covered! When you sign-up you get 300 free prints and you can watch your creations come to life on my printer via Twitch live stream (https://twitch.tv/printercow). Perfect for testing your integration before committing to hardware.

    I'm particularly excited about the AI integration possibilities. Instead of yet another chat interface, you can have AI generate content that exists in the physical world – artwork, poems, todo lists, custom receipts, etc.

    Would love to hear your thoughts, feature requests, or creative use cases you can think of! Also happy to answer any technical questions about the implementation.

Show HN: Pica – Rust-based agentic AI infrastructure (open-source) - Project Screenshot

URL: https://www.picaos.com/

Author: moekatib

Description: Hi HN,

Founder here. We built Pica, an open-source platform in Rust to enable agentic AI with three main focus areas:

- Access to APIs and tools: Universal SDKs that let AI agents use thousands of external actions without blowing up your context window.

  • Visibility and traceability: Full audit logs of every decision/action to ensure transparency and accountability.
  • Alignment with human intentions: Seamless guardrails for autonomous tasks; e.g., restricting certain email actions to human approval.

    Why this matters: As autonomy in AI grows, we need robust solutions for trust and oversight. Pica aims to empower developers with the building blocks for safe and capable agentic systems.

    We’d love your feedback—check it out: https://hellopica.com/

6. Show HN: SudokuVariants – play and construct different variants of Sudoku

Show HN: SudokuVariants – play and construct different variants of Sudoku - Project Screenshot

URL: https://sudokuvariants.com

Author: stanac

Description: Hi HN, I've been working on this Sudoku web app for the past couple of years, on and off during free weekends and afternoons. I started working on it because I was bored during COVID, and Cracking the Cryptic had just become popular on YouTube, which got me wondering how hard it could be to make a Sudoku app. The main idea is for the app to understand the constraints and know how to solve Sudoku grids (and not just be a simple Sudoku drawing/playing app). When it comes to classic Sudoku, the solver doesn't support anything more complicated than X-Wing, but it understands the constraints.

At the moment, most of the popular variants are supported: killer, sandwich, arrow, thermo, palindrome, German whisper, kropki, consecutive, non-consecutive, greater than, XV, diagonal, anti-king, anti-knight, even-odd, windoku, renban, and zipper. The only variant I am yet to add support for is quadruple. If any other variant becomes popular, I will probably add it, as was the case with zipper lines during development.

A user account is not required to play, but it is required if you want to publish a public grid on the app. The app doesn't collect any PII, doesn't have ads or trackers. Accounts are identified by email hash; I am not storing email addresses or passwords, and OTPs are sent by email. The less I know about users, the better for both sides.

The app supports mobile devices, but it works best on bigger screens. It was built using Blazor SSR/WASM (AOT) with SVG for interactive parts. I know there are some performance issues (especially on mobile phones and with touch input), and I am trying to address them.

Some of the features I was thinking about adding are classifying grids by difficulty, daily Sudoku, and maybe campaigns (groups of Sudoku grids where users have to solve them in order).

If you like Sudoku, or more specifically variants of Sudoku, please let me know what you think about SudokuVariants.

7. Show HN: A Product Hunt alternative where products DON'T compete with each other

Show HN: A Product Hunt alternative where products DON'T compete with each other - Project Screenshot

URL: https://saascurate.com/

Author: FilipPanoski

Description: I am an indie hacker and have been launching my products on Product Hunt. Like many of you here, my experience with PH sucked: Lots of bots. Hard to compete.

There's also been many new launch platforms coming up, but all of them make you compete for upvotes. Ugh.

So I have been working on something different: https://saascurate.com/

It's a community-driven platform where indie hackers and SaaS founders help each other grow their products.

The idea is simple - list your product, engage with other founders, gain exposure and social proof. No upvote system.

It's hard and expensive to turn a side project into a viable business, especially for solo makers, so my longterm vision is to be able to help founders grow their products in lots of different ways, like helping with cold outreach, partnerships and other channels.

I know there are a lot of "list your product and forget" platforms, so I am trying to build something different – where the community helps each other grow.

Let me know what you think! I'd love to hear your thoughts and see if this platform can help you grow your products.

Show HN: Hold yourself accountable for gym visits with a $10 stake - Project Screenshot

URL: https://www.gymbully.fit

Author: paul_brook

Description: I don't go to the gym as much as I should or want to. To give myself some financial motivation I made this website.

First you set a goal for how many days you'll hit the gym. To prove you're at the gym, you will verify each visit by pressing a button on your phone (with location sharing on). You stake $10 as motivation and if you hit your target, you get the money back. If you fail, your $10 goes to the "Save The Children" charity with a donation receipt emailed to you.

Obviously you could visit the gym and then just go home without working out - but getting to the gym is half the battle!

It's simple to use with a Google sign-in and hopefully it will encourage some people to workout (or give to charity)!

Show HN: Fixa – an open source Python package for testing voice agents - Project Screenshot

URL: https://github.com/fixadev/fixa

Author: jony1266

Description: hey! this is oliver and jonathan and today, we’re launching fixa — a free, open source package to test voice agents.

fixa uses a voice agent to call your voice agent and an LLM to evaluate how the conversation went. here's a demo: https://youtu.be/LAW1wW6SjTo

this was initially a paid feature of our platform, but the monetization model didn't really make sense.

our customers were paying us for all the components of our agent (STT + LLM + TTS + markup) in addition to their own agent – even though many of them have preferred vendors, volume discounts, and credits.

we came to the conclusion that you should be able to use your own API keys to test your own voice agents.

e2e testing for web apps is done using free and open source packages (selenium, puppeteer), we think the same should be true for voice.

running tests with fixa will always be free. we make money if you decide to use our cloud platform to visualize your test results.

fixa is still in the early stages, so we would appreciate any and all feedback!

Show HN: Gurubase – AI-Powered Q&A Assistants for Any Topic - Project Screenshot

URL: https://github.com/Gurubase/gurubase

Author: fatihbaltaci

Description: Hey everyone,

A couple of months ago, we created Gurubase.io to build RAG-based Q&A agents focused on open-source tools, with the goal of helping developers learn and troubleshoot more effectively. Since then, it has gained momentum, with hundreds of repositories already using it and showcasing it to their users.. https://github.com/Gurubase/gurubase?tab=readme-ov-file#used...

Today, we've released the entire system as an open-source project, allowing you to install it in your own infrastructure and create "Gurus" on any topic you choose.

Current capabilities of Gurubase:

* You can create a Guru by powering it with PDFs, web pages, YouTube videos, or GitHub repositories.

* We present Binge, which visualizes your chat history as a node graph. You can navigate through it and create a personalized path.

* The system includes an instant evaluation mechanism to minimize hallucinations in generated answers as much as possible.

* You can also embed your Guru into your website using an "Ask AI" widget. Check out https://getanteon.com to see it in action.

* Although we initially focused on GitHub repositories, you can now create Gurus on any topic, website, or whatever you want by providing the related data.

We appreciate any feedback. Thanks in advance!

14. Show HN: Couples therapy with AI and Therapists – all in the same chat room

Show HN: Couples therapy with AI and Therapists – all in the same chat room - Project Screenshot

URL: https://therapytalk.io/landing-page/couples-therapy

Author: yardstick17

Description: We build this feature that’s a first in the mental health space: Couples Therapy in a shared chat room with AI and a Licensed Therapist.

Here’s how it works:

  • Three participants in one chat room: You, your partner, and an AI therapist assistant.
  • Therapist oversight: Licensed therapists regularly review the chat, guide the AI, and update therapy plans to ensure real progress.

    Why we built this: A user wrote to us:

    "Hi

    I want to use the website for couples therapy and go for the £80 a month sessions. I was curious to know if there will be a way or method so me and husband can use the chat at the same time and have our own labels such as names, so whenever we have a session the ai can distinguish which message is from who without having to specify it each and every time. I hope it makes sense.

    Kind regards "

    We build this feature in 2 days (awful lot of refactoring to accommodate additional user in the chat room) and we have this user as paid user.

    While many people have used ChatGPT for individual therapy, this concept of couples therapy as a shared experience is entirely new.

Show HN: I made an honest photo cleaner for iOS that puts you first - Project Screenshot

Author: tonymasek

Description: Hello HN!

Driven by the desire to avoid upgrading to the 2TB iCloud tier, I made a photo cleaning app for iOS that helps you systematically review your photos. While there are many similar apps, none of them checked all the boxes for what I wanted:

- Clear privacy guarantee that photos never leave your device

- Being honest about free limit usage. Some apps let you review photos only to reveal you can delete just a couple per day when you try to empty the trash. Basically taking your time hostage, when you've already gone through hundreds of photos

- Context for better decisions. A lot of the apps use swipe-based UIs that only show one photo at a time, making it hard/impossible to see surrounding photos to make a proper decision

- An enjoyable experience with features like zooming and sharing. You should be able to have fun and relive your memories, given you are already doing the tedious task of going through hundreds of photos

I hope that these factors illustrate why I decided to enter this crowded space with my own take. Thank you for your time, and if you consider giving it a look, I would definitely appreciate any feedback.

Show HN: Chart of VCs Success Rate - Project Screenshot

URL: https://startups.mikealche.com/vcs

Author: yoouareperfect

Description: Hey HN,

I’ve been curious about how different VCs stack up in terms of the number of investments they’ve made versus the number of exits (acquisitions, IPOs, etc.) they’ve seen. To satisfy that curiosity—and hopefully share something useful—I created a simple chart that compares VCs’ total investments against their exits.

Why I built this:

I was looking for a quick visual snapshot of which firms are most active and how many of their deals have led to notable exits.

While it’s not a definitive measure of a VC’s success, it’s still an interesting proxy, especially for anyone researching the track records of various funds.

19. Show HN: Crawlspace – A centralized web crawling platform built on Cloudflare

Show HN: Crawlspace – A centralized web crawling platform built on Cloudflare - Project Screenshot

URL: https://crawlspace.dev

Author: andrethegiant

Description: Crawlspace is a centralized web crawling platform that benefits crawler developers AND website owners. Developers can affordably crawl tens of millions of pages per month, scrape with LLMs, and save data in attached storage. Website owners are shielded by a platform-wide TTL cache that absorbs redundant bot traffic.

AI bots are running rampant on the open web. Many recent HN stories[1][2][3][4] describe how web crawlers have run amok and hammer websites with DDoS-like traffic. They often do this with blatant disregard of website owners' wishes (e.g. ignoring robots.txt, 429s, Retry-After headers, etc) because they face no repercussions for deploying poorly-behaved crawlers (and are not incentivized to improve them).

The knee-jerk reaction to fix this problem is to give more tools to website owners. Maintaining denylists of IP addresses and user agents, implementing honeypots and tarpits, etc are tactics that website owners use to combat the problem. However, this ends up resulting in and endless arms race between web crawlers and website owners, as they each try to employ new mechanisms of one-upping each other.

Crawlspace takes a different approach by providing a convenient and affordable platform to web crawler developers. By funneling web crawling traffic through a centralized platform, we can control neat things like making crawlers well-behaved by default, implementing proper caching, and more — all the tedium that that developers don't want to (and therefore, don't) do themselves. Music streaming services like Spotify used convenience and affordability to curb music piracy; we're following the same playbook to curb rampant bot traffic on the internet.

In about 50 lines of code, you can deploy a performant and polite web crawler on Cloudflare's network. Every crawler gets its own queue, SQLite database, vector database, and S3-compatible bucket, which allows you to query your crawl as it's crawling with either SQL statements or a RAG chat interface. We've stitched together 10+ Cloudflare products including Queues, Durable Objects, Browser Rendering, Workers AI, D1, R2, and Vectorize.

Please let us know what you think! Happy to answer any questions.

Show HN: CodeBeam: The missing bridge between browser and IDE - Project Screenshot

URL: https://github.com/gaurav-yadav/CodeBeam

Author: rainmod

Description: I built CodeBeam to solve two core developer frustrations: constant context-switching between browser and IDE, and the tedious process of dealing with errors across different languages and frameworks. What makes CodeBeam different is its universal adaptability. It watches your clipboard with customizable directives for automatic file operations, while simultaneously monitoring your logs for errors using pattern-based detection that works with any language or framework. When it spots an error, it automatically generates AI-ready prompts with rich context, making debugging significantly faster. Think of it as combining an intelligent clipboard manager with an error analysis system that adapts to your stack. Whether you're working with TypeScript, Python, or any custom framework, CodeBeam's pattern-based monitoring system can handle it. Define your own error patterns, customize your prompt templates, and integrate with any IDE or text editor. Built with Node.js, it's lightweight and framework-agnostic. MIT licensed and seeking community feedback, especially from developers working with diverse tech stacks.

Show HN: Chat with multiple LLMs: o1-high-effort, Sonnet 3.5, GPT-4o, and more - Project Screenshot

URL: https://polychat.co

Author: cr4zy

Description: Hello HN! I was fed up switching between multiple UIs to ask GPT, Claude, etc… the same question and comparing the answers. So I built a way to ask multiple models the same question efficiently by having the LLM compare the responses and only show you new and valuable information from the 2nd model. This way you still get a fast response as normal from the 1st model, but also get any added value provided by the 2nd model.

Initially I built my own UI to use this, but stumbled upon Open WebUI (formerly Ollama WebUI) which is fantastic, but is made more for local access to LLMs. So I talked to its creator, Timothy Baek, and he mentioned that security needed to be shored up before production deployment. I did some scans with semgrep, and fixed some XSRF and CORS issues along with making sure the JWT tokens, passwords, etc… were secure. This was in addition to other folks' amazing security contributions. So now we build on Open WebUI! oss ftw

After launching privately a month or so ago and posting a few reddit links, I have about 100 users.

We also just got access to the o1 API and provide o1-high, medium, and low effort. o1 high effort is able to solve coding problems that only o1 pro can also solve, though pro can go further and has better formatting, o1 high effort is a nice option if you don't want to fork over $200/mo.

https://www.reddit.com/r/OpenAI/comments/1i0r867/comment/m70...

You can use o1 for free in PolyChat, which is the only place I've seen you can do so.

You can also ask multiple models the same question and stream the answers simultaneously side by side. https://imgur.com/a/ly5ZPh8

And you can have multiple chats going simultaneously and they will continue in the background and notify you when they're done.

Another cool feature that makes long chats way easier to navigate is the overview (three dots on top right of chat) https://imgur.com/a/PoB1phT

We give you full control, unlike most providers, to change the system prompt, temperature, etc.. in the chat settings in the "Controls" on the top right.

The formatting for code outputs and inputs is fantastic, using codemirror, and you can run code in the code blocks if it's python or JS using in-browser runtimes.

You can also share chats within polychat where other logged in users can see them:

e.g. https://polychat.co/s/ec163812-9323-4cb5-a429-7ddeaf3572c3

Or you can share it publicly to the OpenWeb UI community

https://openwebui.com/c/crizcraig/e1b2fff9-30a3-4ee7-8eed-b2...

Finally we allow you to search and organize your chats into folders which makes finding things super fast!

Infra: My custom backend that combines models and does things Open WebUI doesn't handle like token tracking is written in FastAPI and uses LiteLLM for easily accessing different model APIs. I host everything on GCP using Cloud Run for the backend and use PostGres for Open WebUI's db, along with BigQuery and Firestore for my FastAPI app's db.

Pricing: Our pricing makes it cheap to access top models. It's free at first, then we offer subscription tiers starting at $5/mo which allots about ~1 million tokens per month, enough for most people. But unlike Claude's UI for example, we don't shut you down with rate limits, but rather let heavy users upgrade beyond to $10, $20, $40, $80, etc... We also suggest a plan based on how quickly you used your free tokens, so you have an idea upfront of the monthly cost before you buy. And you can upgrade or downgrade at any time.

23. Show HN: Adaptive-classifier – text classification with continuous learning

URL: #

Author: codelion

Description: Hi HN! I've built a Python library that lets you create text classifiers that can continuously learn and adapt to new classes without retraining from scratch.

What makes this different from typical text classifiers:

- Dynamically add new classes at any time without full retraining

  • Combines neural networks with prototype learning for better few-shot performance
  • Uses Elastic Weight Consolidation to prevent catastrophic forgetting
  • Works with any HuggingFace transformer base model
  • Memory-efficient through prototype-based storage

    You can try it out in under a minute:

    pip install adaptive-classifier

    from adaptive_classifier import AdaptiveClassifier

    # Initialize with any HuggingFace model classifier = AdaptiveClassifier("bert-base-uncased")

    # Add initial examples texts = ["Great product!", "Terrible experience", "Average performance"] labels = ["positive", "negative", "neutral"] classifier.add_examples(texts, labels)

    # Make predictions print(classifier.predict("This is amazing!"))

[('positive', 0.85), ('neutral', 0.10), ('negative', 0.05)]

# Add a completely new class later

classifier.add_examples( ["Error 404", "System crashed"], ["technical", "technical"] )

The library came out of my work on building a model router for optillm where approaches and model types keep changing. Traditional classifiers require full retraining when adding new classes, which becomes impractical with large datasets.

Source code: https://github.com/codelion/adaptive-classifier

I'd love to hear your thoughts and feedback! Happy to answer any questions about the implementation details, use cases, or future plans.

24. Show HN: What if you could "Prompt" the UX of any App?

Show HN: What if you could "Prompt" the UX of any App? - Project Screenshot

URL: https://gen-ux.vercel.app/

Author: 13point5

Description: I saw Pietro Schirano on X demo a chat app that could change its UI tone(dark mode, mario, windows 98, etc) through prompts, and it got me thinking: what if you could go beyond UI and actually change the UX on demand without losing state?

So, I built a to-do list app that lets you prompt it to completely transform the UI and UX.

For example:

- Want a Gameboy-style console UI where the tasks show up one at a time, sorted alphabetically?

- Prefer a Tinder-style interface?

Prompt and you get it!

The magic here is that the app preserves your state (e.g., completed tasks, pending ones, etc.) while letting you experiment with disposable, malleable interfaces.

Although I demoed this with a to-do list, the possibilities are much broader:

A browser with a Tinder-style interface to quickly swipe through tabs when you've got too many.

The broader goal is to explore malleable software: if your data models and operations are well-defined, then the UI and UX can be a flexible function over that, shaped by user intent.

This was a fun experiment in letting people play with software, creating interfaces that adapt to their immediate needs. I'd love to hear your thoughts—especially on where you think this idea could be pushed further.

Show HN: Shepherd – open-source tools to manage self-hosted software deployments - Project Screenshot

URL: https://trustshepherd.com/

Author: henrysg

Description: Hey HN, I wanted to share something I’ve been working on. My startup previously built B2B SaaS, and large enterprises sometimes wanted to self-host it for data residency reasons - but this was a nightmare to build and support. I chatted to other builders/founders and it seems this pain is pretty common. But people tolerate it because the biggest customers often require self-hosting.

So we’ve built and open-sourced Shepherd to make it easier to manage these self-hosted deployments. It’s MIT licensed, and provides:

1 - Simplified deployment with a UI to create and manage Helm charts, for easy deployment to customer Kubernetes clusters

2 - Automated deployment upgrades to improve version consistency and provide rollbacks

3 - Deployment health monitoring

Try it and please share any feedback:

Description: I’ve always enjoyed reading the earnings sections of WSJ to discover new ideas to dive deeper. But I’ve often wanted for a centralized place to access the latest financial reports from major corporations—something that goes beyond editor-curated content to cover the broader market.

Platforms like SeekingAlpha, Quartr, Finchat, Earningshub are fantastic, but they’re often complex, costly, and designed for in-depth stock research. I created something simpler and more discovery-focused, a tool that feels more like reading the morning newspaper.

Show HN: Using Stripe to Disrupt Google/Meta Ads - Project Screenshot

URL: https://sellff.com/offers

Author: 4sellff

Description: Hello HN, Excited to share something we’ve been working on: a new way to connect buyers and sellers that flips the traditional ad model used by Google and Meta. We call it Offers. It’s built on three core principles: privacy, choice, and cash rewards.

How Offers Works

  • For Sellers: Create Offers with cash rewards to generate interest and boost visibility for your products or services.

    * For Buyers: Choose the Offers that interest you and earn a cash reward for each click. In return, provide valuable feedback to the seller.

    * Powered by Stripe Connect: Payments and transfers between buyers and sellers are seamless, secure, and fully transparent.

    The Problem with AdTech Today’s $1 trillion AdTech industry is driven by a massive global surveillance system that tracks your every move online, continuously building a profile of your likes and dislikes. This data is then sold to companies to target you with personalized ads—without your informed consent.

    A Better Way Offers removes the AdTech middleman, creating a direct, equitable, and transparent connection between buyers and sellers. No tracking. No hidden data collection. Just fair exchanges of value.

    Why It Matters If you’re content with the current AdTech model, there’s no reason to read further. But if you’re curious about a more consumer-friendly future for digital advertising, we invite you to experience it for yourself. You can view a live Offer here and earn a $1.50 cash reward for your time:

    https://sellff.com/$/ron.michel/offer/6Nu4M

    We’re eager to hear your thoughts and feedback as we work to redefine digital advertising with privacy, choice, and cash rewards at its core. Join us in shaping the future of advertising. Thanks for your time!

Author: clasnake

Description: Developers have been using platforms like LeetCode to practice algorithm challenges to prepare for coding interviews. But Software Engineering goes far beyond solving algorithm puzzles, both in interviews and in real-world projects. It demands mastery of essential skills including Computer Science fundamentals, system design, scenario analysis and more.

I believe that active learning through practice is more effective than passive consumption of knowledge - just as we learn programming by writing code. That's why I built NootCode, an online judging and coaching platform for practicing these non-algorithmic skills, similar to how developers use LeetCode for algorithm practice. Users can submit solutions, receive immediate feedback and ratings, study detailed explanations, and continuously improve their understanding by acing the challenges.

Author: Hoshang07

Description: Hello HN! I'm Hoshang, Co-founder of Airbook.

We're a team of former data and ops leaders who often struggled with a fragmented analytics landscape—various specialized tools for data pipelines, SQL explorers, BI dashboards, and ad-hoc automation scripts.

These tools, tailored for distinct skill sets, unfortunately failed to integrate effectively, leaving valuable insights isolated within dashboards and disconnected from the operational tools teams use daily to act on these insights.

That’s why we created Airbook. Our platform is as intuitive as 'Notion' but fully equipped to handle everything from data ingestion and BI to activation.

It’s designed to break down silos and bring all your data workflows into a single, cohesive environment.

We're inviting 20 tech startups (typically Series A+ or >$100K MRR) to join our no-risk, 2-week pilot.

We'll set everything up and demonstrate how Airbook can streamline your data operations.

Ideal for:

- Heads of Data or Ops (RevOps, BizOps etc) in growing tech startups.

This is perfect if you’re:

- Looking to set up your first data stack or consolidate multiple tools into one platform.

- Keen on building cross-functional insights across tools like GA, HubSpot, SFDC, PostgreSQL, and Snowflake—whether you code or not.

- Aiming to automate customer segments or engage audiences more effectively with tools like CustomerIO, Clay, HubSpot and more

If this resonates, let’s chat!

We’re happy to have a 15-minute call to discuss your needs and see if we’re a good fit.

Here's my Calendly link - https://calendly.com/meet-airbook/interview-with-airbook

URL: #

Author: emregucerr

Description: Hi HN! We are building an AI agent that can use a computer for software tasks. You can have it review and manually test all your pull requests. Here is a demo video of how it works: https://www.loom.com/share/71135bb2ef784ff593940fbe6fb42c4c?...

We realized the current technology is not yet capable of automating non-trivial software tickets reliably but is pretty good at manual testing code changes for bugs. On the other hand, we knew tools like CodeRabbit got interest from developers yet could only point out obvious bugs or style nits as they are limited by ‘reading’ the code.

Fume can use its own computer. If you’ve made UI changes, it can spin up a browser and click through edge cases. If you’ve made more functional changes, it can write and run test scripts to ensure there are no bugs.

We are language/framework agnostic. The setup is pretty easy. You just install a Github app and set up Fume’s computer (once) like you would set up your local environment.

We’re thinking of adding integrations like PostHog to give Fume more context around using your complex app. We’d love to hear your feature requests too!

We have a 30-day free trial (no CC): https://fumedev.com - please do tell us what you think!

URL: https://github.com/stanfrbd/cyberbro

Author: stanfrbd

Description: Hello,

my name is Stan and I'm really excited to share my first real cybersecurity Open Source project, Cyberbro.

Why Cyberbro? Because it's lightweight and self hosted. And because I wanted to make an Open Source project. It's not perfect, but it works.

It's a tool that can be connected to multiple cybersecurity APIs to give contextual info about a potential Threat (Observable, not yet IoC without context).

Supported observables are: IPv4, IPv6, domains, SHA1 hash, SHA256 hash, MD5 hash. The project has now 190 stars on Github and I released the v0.1.0.

Supported APIs are: VirusTotal, OpenCTI, Grep.App, Microsoft Defender for Endpoint (EDR), Google Safe Browsing, IPinfo, AbuseIPDB, Shodan

Free included tools are: IPquery, Google search (scraping), Ioc.One (scraping), Phishtank, Threatfox, Abusix

Tech stack:

Python 3.13 - Flask - HTML/CSS/JS - Docker for deployment

This tool is used in my corporation (I'm really proud of it).

I developped an API to automate stuff.

Any individual wanting to check IP reputation can go to demo.cyberbro.net and give it a try (the demo is online for 1 month as I tell).

Other cool features are that you can export the results in CSV or Excel (formatted properly).

I hope you will find it interesting!

Cheers,

Stan [stanfrbd on GitHub]

Author: allanblair_

Description: Hey HN, I wanted to share bframe an open source billing library I've been working on. The business logic is primarily in SQL and the launch client is in python.

bframe is a wrapper around a duckdb connection which makes it easy to extend and understand.

The largest difference between bframe and alternatives is how we treat persistence. The library connects to an existing store (bring your own infra), while other solutions use their own storage.

This has several benefits if you are willing to provide your own store: a single source of truth (no weird syncing), the library can be directly used without a server (e.g. pip install bframelib), sources are generally fungible (use CSVs, JSON, postgres, etc).

bframe does a lot more which can be seen in our documentation: https://bframe.work

The github repository can be found here: https://github.com/bframe-work/bframelib

The project is still very much in development so I appreciate the feedback. If this project interests you and you'd like to chat more send me a message @ allan at bframe.work

URL: https://github.com/cloudcoil/cloudcoil

Author: samj1912

Description: Show HN: CloudCoil – Production-ready Python client for the cloud-native ecosystem

I built CloudCoil (https://github.com/cloudcoil/cloudcoil) to make cloud-native development in Python feel first-class, starting with a modern async Kubernetes client. Frustrated with existing tools that felt like awkward ports from Go/Java, I focused on creating an API that Python developers would actually enjoy using.

Installation is as simple as: uv add cloudcoil[kubernetes] # Using uv (recommended) pip install cloudcoil[kubernetes] # Using pip

Key features:

  • Elegant, truly Pythonic API that follows Python idioms

  • Async-first with native async/await (but sync works too!)

  • Full type safety with MyPy + Pydantic

  • Zero-config pytest fixtures for K8s integration testing

    Quick taste of the API:

        # It's this simple to work with resources
     service = k8s.core.v1.Service.get("kubernetes")

    Async iteration feels natural

    async for pod in await k8s.core.v1.Pod.async_list(): print(f"Found pod: {pod.metadata.name}")

    Create resources with pure Python syntax

    deployment = k8s.apps.v1.Deployment( metadata=dict(name="web"), spec=dict(replicas=3) ).create()

The ecosystem is growing! We already have first-class integrations for:

- cert-manager (cloudcoil.models.cert_manager)

  • FluxCD (cloudcoil.models.fluxcd)
  • Kyverno (cloudcoil.models.kyverno)

    Missing your favorite operator? I've made it super easy to add new integrations using our cookiecutter template and codegen tools.

    I'd especially love feedback on:

  1. The API design - does it feel natural to Python devs?
  2. Testing features - what else would make k8s testing easier?
  3. Which operators/CRDs you'd most like to see integrated next

Show HN: Learn Japanese Watching YouTube - Project Screenshot

URL: https://www.seikai.tv/

Author: flippyhead

Description: I had a successful startup exit five years ago (we got very lucky) but recently realized I'm most happy when building software products. I spend the last ~2 months building this as a fun way to get back into software development; and to find out what all the kids are up to these days. I am also a passionate life-long Japanese learner so this project was really fun. It's been nutz how different things are now with all the AI whatnot. This for sure would have taken me a year, without all the AI.

I did not spend much time doing market analysis or any of that jazz. Mostly because I was interested in the journey of building the product. Shocker, there's a bunch of other people/companies doing similar things. Of course, mine is already waaaaaaay better! And different in tiny, hard to understand, but essental ways! Ahem.

I don't know if it can make much money. I don't care really if it does. I personally have been using it and, of course, love it for my style of learning Japanese. It could be interesting, to spend another month, exploring how AI and the latest tools have changed the marketing and customer aquisition process.

Anyways, I'd really appreciate your feedback. On the product, on the idea, on the journey. There's been a few stories here lately about how hard it is to do start ups. Going through the process with this one really brought back some memories, equal parts joyful and painful. Since it only took me two months and I don't really need the money, it's been a lot easier to just enjoy the process without stressing too much. But man, it's easy to get stressed too when you see how many obstacles there seems to be to have even a modest success. It's so hard to stay motivated. I'm pretty sure going forward I just want to make things for the joy of it.

What I really wanted was a companion that would just talk to me about my hobbies, interests, and news in an engaging way - like a friend that shared my interests would. That's how I set out on creating Oliver.

Check it out by signing up at fissure.ai or just texting 866-642-8184.

Oliver will text you through SMS and will:

  • Chat with you about everyday things.
  • Learn your interests and hobbies through what you mention to him.
  • Digest and formulate opinions and knowledge on media you share with him (right now links to articles and YT videos) and talk to you about them.
  • Reach out to you with media that Oliver thinks you would like.

    I have a long list of plans for Oliver and am excited to keep working on it. This is far from a final or finished product. Would love early feedback and comments.

Show HN: I Built a QA Agent to Detect Broken Web App Flows – E2E Test/Regression - Project Screenshot

URL: https://alertdown.ai

Author: superjose

Description: Hi everyone!

I’m Jose, the solo founder of AlertDown, an automated user flow monitoring tool for web apps. It notifies you when something breaks—before your users do.

Imagine end-to-end tests with real-time monitoring, catching regressions and silent failures without:

• Writing a single line of code • Installing any dependencies

Just add your URL, and AlertDown will:

  1. Extract all possible user actions (clicks, inputs, dropdowns, etc.)
  2. Automatically test each flow, branching out dynamically
  3. Detect silent issues like:

    • Missing dropdowns • Unresponsive buttons • Third-party API failures

    Unlike tools like Sentry or Datadog, these errors often don’t show up as obvious failures, which can lead to lost revenue.

    Why I built this:

    While working at a cash-constrained startup (not mine), we lost $1,347 in revenue due to a misconfigured feature flag at step 7 of our onboarding. We didn’t realize it until 3 days later—after a user reported it. :(

    I’ve seen this issue repeatedly over the years:

    • “Non-breaking” code silently causing regressions • Third-party services failing unexpectedly • Testing fatigue—running the same flows over and over manually

    I thought an automated solution like this wasn’t possible, but after an initial POC and 5 months of work, it’s finally live and working!

    Tech Stack: • Remix, TypeScript, Vite • Supabase • Docker on Google Cloud Run & Compute Engine Temporal.io for orchestration

    What’s Next:

    I’d love your feedback and ideas as I continue improving:

• Handling login screens • Slack integrations for alerts • Custom viewport testing

Try it out now (for free)! I'm looking for some early adopters that would like to pilot the product.

You can access without paying (just head to the login page)—it’s currently in public testing!

Looking forward to your thoughts and feedback.

P.S: And if you are part of a company or building your SaaS, I want to work close with you to craft a unique experience.

Show HN: Template2PDF Templates to PDF API - Project Screenshot

URL: https://template2pdf.com

Author: seven

Description: Hey all,

same idea 10 years later :)

https://news.ycombinator.com/item?id=7892813

Life got in the way and I abandoned the project.

Then I needed it for my own use, so now back, with a slightly different approach:

Normal google docs as templates. API even simpler.

Just finished building a zapier integration - hope I can publish it soon.

Hope to get some feedback and perhaps even some people to test it.

As always, thanks for your time :)
