1. Show HN: I convert videos to printed flipbooks for living
URL: https://www.videotoflip.com/
Author: momciloo
Description: I built this product back in 2018 as a small side project: a tool that turns short videos into physical flipbooks. After launching it, I didn't touch it for years. Life and work took over, and it sat idle. But it kept getting a few orders every month, which made it impossible to forget. So in December 2024, I decided to rebrand and revive it.
The initial version relied on various local printing offices. I kept switching from one to another, but the results were never quite right. Either the quality wasn't good enough, or the turnaround times were too long. Eventually, me and my wife bought all the necessary machines and moved production in-house.
Now, it's a family business. My wife and I handle everything: printing, binding, cutting, addressing, and shipping each flipbook. On the technical side, it’s powered by Next.js, with FFmpeg extracting frames and handling overlays, and ImageMagick used for adding trim marks and creating the final PDFs.
After many years of working in IT, working on something tangible feels refreshing. It's satisfying to create something that brings people joy. And that is not hard to sell (like dev tools, for example haha). There are still challenges: we're experimenting with different cover papers, improving production, and testing new ideas without making things confusing. But that’s part of what keeps us moving forward.

2. Show HN: Klarity – Open-source tool to analyze uncertainty/entropy in LLM output
URL: https://github.com/klara-research/klarity
Author: mrciffa
Description: We've open-sourced Klarity - a tool for analyzing uncertainty and decision-making in LLM token generation. It provides structured insights into how models choose tokens and where they show uncertainty.
What Klarity does:
- Real-time analysis of model uncertainty during generation
- Dual analysis combining log probabilities and semantic understanding
- Structured JSON output with actionable insights
- Fully self-hostable with customizable analysis models
The tool works by analyzing each step of text generation and returns a structured JSON:
- uncertainty_points: array of {step, entropy, options[], type}
- high_confidence: array of {step, probability, token, context}
- risk_areas: array of {type, steps[], motivation}
- suggestions: array of {issue, improvement}
Currently supports hugging face transformers (more frameworks coming), we tested extensively with Qwen2.5 (0.5B-7B) models, but should work with most HF LLMs.
Installation is simple:
pip install git+<a href="https://github.com/klara-research/klarity.git">https://github.com/klara-research/klarity.git</a>We are building OS interpretability/explainability tools to visualize & analyse attention maps, saliency maps etc. and we want to understand your pain points with LLM behaviors. What insights would actually help you debug these black box systems?

3. Show HN: Check Supply – Send Checks in the Mail
URL: https://check.supply
Author: pfista
Description: When I lived in SF, my landlord required rent payments via check. For a while I just used my bank's bill-pay. If you remember Simple, they eventually killed their bill pay feature, and then they later shutdown altogether. I didn't want to buy a checkbook, stamps, and envelopes just for this one bill.
That's why I built Checks Supply with a friend to make check sending as simple as sending cash on Venmo. With our app, you can fill out your check details and have your payment processing within minutes after downloading.
Check writing is becoming a rarity, and many first-time senders find the process daunting. We hope Check Supply is a quick and convenient option for those moments you're puzzled why someone is asking you to pay by check.

6. Show HN: Apitally – A simple, privacy-focused API monitoring and analytics tool
URL: https://apitally.io
Author: itssimon
Description: G’day Hacker News, I’m Simon Gurcke, the sole founder of Apitally (https://apitally.io).
I’m building a simple API monitoring and analytics tool for Python / Node.js apps. It helps users understand API usage and performance, spot issues early and troubleshoot effectively when something goes wrong.
Features include:
- Dashboards: Provide insights into API traffic, errors, performance and consumers.
- Request logging: Opt-in and highly configurable in terms of what data is logged. Users can drill down from aggregated metrics to individual requests (proven to be super helpful when troubleshooting issues).
- Custom alerts: Based on 14 different API metrics with notifications delivered via email, Slack or Microsoft Teams.
- Validation error tracking: Captures metrics about which fields failed validation and why. Works for web frameworks with built-in validation (e.g. FastAPI with pydantic), or that integrate with popular third-party validation libraries (e.g. Zod for Hono).
- Server error tracking: Captures exception details and stack traces for 500 error responses. An integration with the Sentry SDK also captures event IDs, allowing users to click through to the relevant Sentry issue for more context.
I first started developing Apitally to scratch my own itch. While working at a health tech company where I was responsible for API-based software products, I became frustrated with the monitoring tools we had in place - Datadog and the ELK stack. They were too complex for my API-centric use cases, and often a pain to use.
As a result, I focused on making Apitally as simple as possible. This involved not just refining the UX of the dashboard, but also optimizing the developer experience with the open-source SDKs:
- https://github.com/apitally/apitally-py - Python SDK (supports FastAPI, Flask, Django, Litestar, Starlette)
- https://github.com/apitally/apitally-js - Node.js SDK (supports Express, NestJS, Fastify, Koa, Hono)
My other focus was on data privacy, as that is a strict requirement in the healthcare industry. By default, Apitally doesn’t capture any sensitive data - metrics are aggregated on the client side (similar to Prometheus) and sent in the background in regular intervals.
The hardest part has been implementing integrations for various web frameworks and supporting a wide range of versions. I learned a lot about the inner workings of web frameworks in the process. Good test coverage and an extensive test matrix were really important to not break people’s production APIs with buggy middleware.
Apitally’s backend is built in Python and runs on a small Kubernetes cluster on DigitalOcean. It uses PostgreSQL and ClickHouse to store data and NATS JetStream as a message queue. I chose NATS for being lightweight and its exactly-once processing capabilities. I’m also impressed by ClickHouse’s performance given the low hardware specs of my server (4 vCPUs, 8 GB RAM).
Apitally is free to use for small hobby projects (with limitations), and I offer two paid tiers for $39 and $119 (USD) per month. The dashboard has a demo mode, allowing people to explore the product without having to set up their own app first.
Thank you for reading about my bootstrapped indie product. Please let me know your thoughts and questions in the comments.

11. Show HN: Open-source version of OpenAI's Deep Research
URL: https://github.com/nickscamara/open-deep-research
Author: nickca
Description: Last night, OpenAI launched Deep Research, a tool for AI-powered deep web searches. In a few hours, I built an open-source alternative using Next.js, Firecrawl, and Vercel's AI SDK. Instead of using a fine-tuned version of o3, this method uses Firecrawl's extract + search with a reasoning model to deep research the web.
The system is built using Vercel’s AI SDK for handling requests and streaming data, with an agent-based approach that manages search, extraction, and analysis. It uses Firecrawl to find and extract structured data, which is then processed through a progressive analysis system to refine and summarize results. The process follows an iterative cycle: Firecrawl’s /search API finds relevant URLs, /extract pulls structured data, and a planning function determines what to look for next. A research state tracker keeps track of findings, summaries, and progress while enforcing depth (maxDepth) and time limits to stay within Vercel’s function execution time constraint. The results stream into a live UI, showing search progress, sources, and key insights. The cycle continues until enough information is collected or limits are reached, producing a final structured summary.
This was a pretty fast built and I wanna keep iterating on it. Would love to hear your thoughts.

Author: Dallas_B
Description: https://www.resumevue.com/board
For anyone currently stuck in the grind of endlessly applying for jobs, I completely understand your frustration. I’ve been job hunting for the past four months, and it’s been painfully repetitive and time-consuming. Applying via LinkedIn often feels like throwing your resume into a sea of 1,000+ other applicants, even with daily alerts turned on.
What worked better for me was following founders, recruiters, VCs and other key connections. I’d wait for them to post about roles to their network and apply directly by sending them a DM. This strategy landed me a few interviews, more than going via traditional application portals.
To make this process less manual, I built a tracker that highlights posts from people sharing roles with their private networks. It’s 100% free, so feel free to check it out if you’re in the job market!

Description: Searching for job roles in tech? I've been there. For six months, I was stuck in the LinkedIn job application loop, getting nowhere. It was soul-crushing. I started to wonder if I was just a bad developer.
But I changed my modus operandi and started reaching out to founders building super cool startups that got recently funded but didnt have the chance to post online yet that they are hiring, the response rate was much more significant and I wwas having super cool convos!
This approach was so effective, I turned it into a product. I've tapped into premium data sources (we're talking $25K+ worth) to build a tool that connects talented devs like you with these hidden opportunities.
I am looking for a few more spots to test the beta out and launch, running a special promotion for the beta users

17. Show HN: Open-source application to run local LLM easily
URL: https://kolosal.ai
Author: rifkybujana
Description: Kolosal is a simple desktop application to run most LLMs on both CPU and GPU. It is designed to be easy to setup, to run, and to embed, with only 30mb (extracted).
It is inspired by ollama and lmstudio. While lmstudio have a very easy and beautiful interface and also very easy to setup, but i saw people are looking for an opensource alternative to it. In other hand, ollama is opensource, can be easy to setup (but for some user, who have AMD gpu RDNA2 below RX6800 it might be complicated to run it on GPU), but to be use by normal person, you need to run other application or webui that add some complexity to it.
So there you go, a simple, light, opensource desktop application run on your device!
Also, you might notice that there are some features that is shown in the website, but haven't actually made into the application, especially the inference features, we're still working on it (we just launch our first mvp at 10th January 2025). The inference features is made to address the accuracy issue at small models that can be run on non-GPU devices.

18. Show HN: Synaps Media – Managed Ghost CMS Hosting
URL: https://www.synapsmedia.com/
Author: muratcorlu
Description: Hi HN,
I’m Murat, a software engineer based in the Netherlands, and I’ve been building Synaps Media, a fully managed hosting service for Ghost CMS.
I love Ghost as a publishing platform, but I found self-hosting frustrating, managing updates, security, backups, and performance optimizations is time-consuming. Official Ghost(Pro) hosting is great but might be overkill for some users. I wanted to create an alternative that’s simpler and more affordable, especially for independent creators and small teams.
What Synaps Media Offers
* Managed Ghost hosting with no technical setup required
- No hard limits on content, visitors, or members (except 2,000 newsletter emails/month)
- Multi-site management for freelancers & agencies
- Built-in CDN (Bunny.net), SSL, automatic updates, daily backups
- €4/month (€48/year) pricing, with a 14-day free trial
- Upcoming domain management & email services
Why I Built This
I started Synaps Media in early 2024 as a side project and launched privately with a small group of early adopters. It’s now hosting 30+ Ghost publications, and I’ve been refining it based on user feedback. My goal is to make Ghost hosting as accessible as possible, whether you’re an independent writer, a business, or an agency managing multiple sites.
Thoughts & Feedback?
If you’ve ever self-hosted Ghost or used a managed hosting service, I’d love to hear about your experience. What worked well? What didn’t?

21. Show HN: I rebuilt my failed startup from 2 years ago and open-sourced it
URL: https://github.com/usertour/usertour
Author: winterissnowing
Description: Two years ago, I embarked on a journey to build a user onboarding tool for non-developers. My goal was to create a solution that would help non-technical users build product tours for their apps without any coding. However, the project ultimately failed due to several reasons—technical limitations, poor market fit, and the wrong approach to user experience.
Through this experience, I realized something crucial: the existing tools on the market didn’t fully meet the needs of either developers or non-developers. Open-source libraries like Intro.js, Shepherd.js, and driverjs were overly simplistic. They lacked essential features like product tour management, customizable start rules, segmentation, and data tracking. On the other hand, paid SaaS tools such as Appcues, Userpilot, Userflow, Userguiding, and Chameleon, while rich in features, often claim to be non-developer-friendly. Yet, non-developers frequently struggled to configure complex product tours, resulting in issues like "element not found" and software instability—issues that, as a developer, I find intolerable.
Reflecting on my previous experience and lessons learned, I decided to rebuild my idea with a new focus—one that catered directly to developers. I wanted to create a product onboarding solution that offered the flexibility of open-source tools while including the full features that developers need to manage product tours effectively and without expensive SaaS limitations.
That’s how UserTour was born. It’s an open-source, developer-friendly user onboarding tool designed to address the shortcomings of existing solutions. With features like product tour management, customizable start rules, segmentation, and data tracking, UserTour is tailored to help developers create robust and seamless onboarding experiences.
I’m excited to share UserTour with the community and invite developers to collaborate in making it the ultimate user onboarding tool. The project is open-source, and I welcome your feedback and contributions to improve it.

Description: Hey HN!
I spent the last couple of months creating a Chrome extension that lets you instantly run Python code from any webpage, including ChatGPT, Claude, DeepSeek & Google AI Studio.
LLMs have made Python more popular than ever, but setting up a Python environment is still tricky. This solves that by letting you simply right-click any Python code snippet to run it in your browser.
You can save snippets and re-run them later, upload/download files, visualize data and schedule automatic runs.
It uses (the amazing) Pyodide for local execution, which supports pandas, requests, BeautifulSoup and lots more. Scheduled runs use an isolated Python environment in AWS Lambda. The code snippet detection is surprisingly simple - it just looks for the parent pre/code tag!

27. Show HN: Kendrick Lamar appears 4x in top most syllable-dense Billboard hits
URL: https://syllablecounter.io/studies/billboard-top-100-data-study
Author: jambar
Description: We analyzed the Top 100 Billboard songs by syllable count, word count, character count, and average syllables per word.
We believe that the average number of syllables in an artist’s lyrics are a big indicator of musical proficiency, for the same reasons that syllable counts are used as a primary input in Flesch-Kincaid readability testing. Through our research we aim to more objectively and quantitatively determine how complex a musician is.
A few interesting takeaways:
-Kendrick Lamar appears 4 times in the top 10 songs by syllable count, speaking to his lyrical complexity and dense rhyme schemes
-Not Like Us by Kendrick Lamar has the most syllables, words, and characters of any song in the Top 100 Defying Gravity by Cynthia Erivo and Ariana Grande is the longest song in the Top 100 at 7 minutes and 40 seconds.
-The average length across all Top 100 songs is 3 minutes and 29 seconds.
-Bad Bunny appears in 6 of the top 10 songs when considering average syllables per word, meaning he packs more syllables into fewer words compared to other artists. This could indicate a broader trend in reggaeton and Latin trap toward more complex lyricism.
Would love your feedback on how to improve our data study (and the site overall) before we circulate it more widely. Thanks!

39. Show HN: PricePilot – A New Price Comparison Platform
URL: https://www.trypricepilot.com/
Author: ivanrlio
Description: Hey HN,
I'm digital designer who has decided build a few different products the last 6 months: a web scraper that scrapes US ecommerce sites, a product API to store this information, and what I'm presenting to you, a price comparison shopping experience.
For now, I introduce PricePilot, a price comparison platform that allows people to compare product prices between US retailers like Best Buy, Amazon, and Walmart, with many more retailers to come in the future.
My humble ask:
- I would appreciate any feedback on the experience so far! What do you like? Not like? Any general thought or feedback.
2) Please share this with your community, network, friends, family!
3) Lastly, I'd appreciate if you could use my site to shop and then click on any of the Best Buy US or Amazon US links if you're looking to make a purchase on those sites within 24 hours. I would make a small commission and that would go a long way with helping me keep this project running as it's been all burn so far.
Thanks so much, Ivan

43. Show HN: Free Crunchbase Alternative with Semantic Startup Search
URL: https://startup-seeker.com
Author: hendrik_cor
Description: I struggled to find other startups doing similar things because keyword searches missed so much. Only to come across a startup doing the exact same thing a week later. So, as a side project, I built a semantic search engine that allows people to search based on descriptions rather than exact words. It’s been incredibly helpful for me, and I hope it can help others too!

46. Show HN: I made a travel website over the afternoon with Bolt
Author: cod3boy
Description: Whenever I visit a new city, its almost impossible to find the best places the city has to offer on Google Maps. I simply want popular places (say 1k reviews or more) AND 4.5 stars or more rated places. Google makes it so hard. So this afternoon I made a small app with Bolt just to do that. If you search a city, it will show you the best places with more than 1k ratings and over 4.5 stars. No much customizations.
PS: I also programmatically create a blog about the city you just searched and add it back to the website. Not bad for an hours work in the afternoon.

48. Show HN: A Prompt Octopus in VSCode
URL: https://promptoctopus.com
Author: BenGuz
Description: Hey HN, I’m Ben, and I’ve been tinkering with prompt-iteration tooling for about a year. My first idea [1] was an open-source tool that lets you try different variations of prompts, but even though I used it endlessly for the first 5-ish days, I… never used it again.
I wrote other scripts, compiled personal eval sets, and subscribed (then unsubscribed) to a bunch of online tools. Nothing seemed right.
Until last Friday when, talking about side project ideas with my girlfriend, she said, “What if it was in your code editor?”
And I thought, wow, I love this woman.
This VSCode extension instead lets you highlight your prompt text and run it against any and all models [2]. You can toss in your API keys, which are only stored locally, and use it for free.
Any feedback would be invaluable - this is my first extension!
I’ll be adding the same highlighting functionality I have for prompts to schema validation, where you can highlight any form of schema (pydantic, zod, json), and I’ll use a small llm to parse it + format it for different providers.

50. Show HN: Semaphor: Embed SQL+Python based dashboards in your product
URL: https://www.semaphor-analytics.com/
Author: rohitspujari
Description: I’ve been frustrated with the current state of embedded analytics. Most tools fall into two extremes: clunky drag-and-drop interfaces with proprietary languages (like DAX) or full-blown notebooks that aren’t built for speed.
There’s a missing middle — a workflow that balances flexibility and ease of use, letting you handle complex data without requiring you to code everything from scratch.
So we built Semaphor: an open-standards approach that lets you use SQL & Python to build beautifully styled dashboards 10x faster without the bloat or high costs of traditional BI tools.
Most embedded solutions (Power BI, Looker, Tableau) are slow, expensive, and proprietary. We wanted something fast, lightweight, and designed for modern web experience.
How is it different?
- No bloat: Build dashboards using natural language, SQL and Python.
- Fully white-labeled: Customize everything. Your brand, your experience. You can also bring your own charts and components.
- Framework-native: React/Vue/Web components components, no clunky iFrames.
Who is this for?
If you’re a SaaS company, marketplace, or product team looking to embed analytics seamlessly into your product, you would love what we're building.

Author: bagoodexAI
Description: Hey HN, I'm Paul, the founder of Bagoodex, and I’m excited to share what we’ve been up to! Over the past few months, our dedicated team has poured their hearts into creating Bagoodex — an innovative search engine and chat platform that uses AI to transform the way you find and interact with information. So, what’s Bagoodex all about? Well, think of it as your personal assistant for searching online! We’ve designed it to help you cut through the noise and get straight to the good stuff, fast. People often struggle with traditional search engines — the overwhelming amount of irrelevant results and concerns about privacy. We wanted to change that! Here’s what you can expect from Bagoodex:
- Smart AI Algorithm
- Real-Time Results
- Privacy First
- Simple and Clean Interface
- Multilingual Support
The idea for Bagoodex came from our shared frustration with traditional search engines. We felt overwhelmed by irrelevant data and concerned about our privacy. We set out to create a tool that not only gives you reliable answers but does so with respect for your privacy and a great user experience.
- A Few Things We’re Working On:
We’re always learning and evolving our AI model, so sometimes it might not hit the mark perfectly.
We’re optimizing for better performance and addressing edge cases as we grow. While our codebase is meticulously maintained, we're not open source just yet! But rest assured, we’re thinking carefully about which parts we might share in the future. Check us out at www.bagoodex.ai. We’d absolutely love to hear your thoughts: Does this sound like something you’d find useful?
What features are you itching to see?
Any insights on open-sourcing that you’d be willing to share? Thanks for reading, and we can't wait to hear what you think!

56. Show HN: I made a local universal file converter that keeps your files private
Author: jakemanger
Description: Hey HN! I made How to Convert. Here's the problem I had and the solution I thought of:
Problem
When you search "How to convert PNG to ICO" on Google, you get a bunch of shady looking "free" results that send your data to unknown servers. The same is true for almost any conversion you are trying to do.
So what do I want? I want something I can trust completely. AKA locally running, doesn't send my files or data anywhere and built by an independent developer building in public.
Solution
How to Convert
Privacy-first: Files stay on your device and it works offline.
Wide compatibility: Works with nearly any file type in an all-in-one app. If your file type is not yet supported, submit an issue to get it added!
Unlimited use: One purchase, infinite access.
Runs anywhere: Runs on Mac, Windows, Linux or the Web.

58. Show HN: Mock-back end an alternative to back end services
URL: https://gitlab.com/ian_g/mock-backend
Author: ian-g
Description: Hi all,
I've been working on some classes and tutorials recently that need to use a backend and were filmed using firebase's free tier.
That's a great option, but I didn't want to use it, so I built this instead. It's meant to be a minimally viable backend for tutorials. I started it as a single-file flask server and made some edits over time to enhance it as needed.
Because I was sick today, I could put some time into it and split it out of its single file + add some testing. It's slipshod, but it works, and I hope it'll be useful for someone in a similar situation in the future.
