1. Show HN: State-in-url package for state management with URL sync
URL: https://github.com/asmyshlyaev177/state-in-url
Author: asmyshlyaev177
Description: I spent some time to build an NPM package about state management (another one, I know) for Next.js/React.js.
Idea: Storing web application state in URL, It’s a bright idea to use URI, but there isn’t a simple and good implementation. Can save state of forms, or filters, users can reload page or share the link.
Demo to play around: https://state-in-url-asmyshlyaev177.vercel.app/
What I wanted to achieve and why The World need another library:
- Storing complex objects, e.g. any valid JSON with nested fields.
- Focus on Developer Experience and simplicity, API similar to React.useState.
- Preserve type of every field, e.g. string|number|boolean|etc, Typescript obviously.
- All my SE experience and best practices, CI/CD pipeline, proper tests, design patterns, JSDoc comments and documentation, so just showcase my skills and possibly get a good job.
- Support Next.js 14/15 and React-router@6, also few hooks that don’t depend on specific framework.
Will be glad to hear feedback and your thoughs, don’t forget to star a repo and/or share it somewhere if it’s useful.

5. Show HN: I curated 500 YouTube daily surfing videos, organised by date and break
Author: 200_OK
Description: I built this site just because I wanted it to exist. I’m a keen surfer who lives near one of the worlds surfing epicenters; the Gold Coast, Australia. Getting home from a surf I’d often get excited seeing videos on YouTube of the breaks and waves I’d surfed that day. There’s hundreds of these daily surf videos on YouTube and I thought it would be good to document and organise them like a historical archive.
The volume of videos posted tends to peak when significant swells arrive so I think I could build some interesting visualisations and maps in the future. I also want to add some kind of community tagging feature so that you can tag which days and breaks you surfed and create a personal diary.
If you also surf and enjoy surf videos let me know what you think.

8. Show HN: I made a in-browser AI agent for fixing bugs in Node, TS and JavaScript
URL: #
Author: Rikard_wikstrom
Description: So for the past month or so, I’ve been working on a browser-based AI agent called Flytrap for automating the most dreadful part of software dev; fixing bugs.
It’s completely free to use, so you can try it out, no signup needed here: https://useflytrap.com/ai
I wanted to ship it as fast as possible, to get real feedback how it performs for real world dev tasks, so all feedback is super appreciated! You can submit a task in the product, if the agent doesn’t perform a task well, and I’ll try to use those submissions to improve Flytrap
It contains 2 agents:
- LLM Agent: This one is meant to be the bug-fixing AI agent, but I need to fine-tune it more to become better. It can perform tasks like read and write FS, execute shell commands etc.
- Simple Agent: This one is quite practical, it can write code, and then verify that it works as expected, so you can use it for code-snippets, that are verified to work (this eliminates hallucinations)
Some features:
- Browser based, so all your files are only accessible by you, saved on your localStorage
- Clone from GitHub supported
- Free to use
Next up I’m working on:
- Making the agents more robust (fine-tuning)
- Linear & GitHub integrations: one-click GitHub issue or Linear issue, agent clones repo and starts working on the task.
- Browsing ability
Would love to hear brutally honest feedback
Join the Flytrap Discord to give feedback Thank you so much!

11. Show HN: My Voice AI interviews you, then writes your LI / X posts
URL: #
Author: tmshapland
Description: I’m Tom, the cofounder of Canonical AI. I build a Voice AI agent that interviews you, then writes LinkedIn and X posts based on the interview.
### Why did I build this?
1. LinkedIn and X are b2b lead goldmines. But generating content is hard. You have to figure out what to say. If you’re like me, you have trouble coming up with social post ideas when staring at a blank screen. But interesting ideas arrive when I step away from my laptop and talk to people. Also, it’s hard to compose the content in a way that appeases the platform algorithms.
2. I want to dogfood my product. We’re building Mixpanel for Voice AI Agents (https://voice.canonical.chat/). We map the caller journeys. We provide audio metrics like latency and interruptions. We show Voice AI devs why and when their agents are failing. I want a Voice AI agent so I can be a user of my Voice AI analytics product.
3. Voice AI will eat the world! This project is essentially a Voice UI for a social media content generation platform. We’re seeing more and more Voice AI interfaces like this (e.g., NotebookLM converts any content into a podcast), and many more use cases for Voice AI agents.
### How did I build this?
I built the Voice AI agent using Vapi (https://vapi.ai/). Vapi is amazing! It’s by far the best end-to-end Voice AI platform out there. I actually had to add latency to the Voice AI. I am a slow thinker / talker and it was unrealistic that my Voice AI clone would respond at normal human intervals.
I cloned my voice using PlayHT (https://play.ht/). Yes, my voice really is that airy. I wish I could say it’s an issue with PlayHT’s voice cloning, but it’s spot on.
The hardest part has been making the social posts feel like they weren’t written by an LLM. I initially was using 4o-mini, but they definitely felt written by…well…GPT. I broke the steps into smaller pieces, making one LLM call that extracts the key insights and quotes and another LLM call that generates the content. That helped, but the social posts still felt LLMy. Then I switched to using Claude. That made a big difference. I love Claude. I use Claude so much I’m not sure where I end and Claude begins.
I’d love to hear suggestions from the community on how to make the LLM-generated content feel less, as a friend of mine said, boring AF.
### Example Output
LinkedIn:
Did you know that most Voice AI agent developers are still manually listening to call recordings?
It’s a time-consuming and ineffective approach to knowing what your agent is doing. It’s like drinking from a fire hose.
At Canonical AI, we’re changing that by providing Voice AI developers with caller journey maps, audio metrics, and conversation analytics.
X:
Voice AI developers are currently flying blind. At Canonical AI, we’re changing that by building Mixpanel for Voice AI agents.
You can see more on my recent posts on my LinkedIn (https://www.linkedin.com/in/tom-shapland-b4494212/) and Twitter (https://x.com/tom_shapland).

15. Show HN: My Version of Whoishiring
URL: https://whoishiring-app.fly.dev/
Author: hazzel
Description: Hello HN!
I built this over a year ago, but never shared it broadly with people - just selfishly used it for myself.
But as I’m now back on the job market looking for a new role, I started using this myself and I figured this could be helpful for others as well.
My original goal was to make a version of https://hnhired.fly.dev/ but with two features I wanted:
1. Have a ‘save’ button to save the jobs I find interesting and revisit them later. No login or account required. Just filter by ‘saved’ jobs and see them.
2. Share a filtered list of jobs with other people. Any filter I apply, I can copy the URL and share it with other people. They would see the exact same result … but I never really used this feature much myself.
In any case, enjoy!
And if you have feedback that could make this more helpful for you or for other people, let me know.

16. Show HN: Open-source library documentation for LLMs
URL: https://docs.codes/
Author: rohansood15
Description: Docs.codes generates simple markdowns for open-source libraries that you can add to the context of your LLM assistants, helping them generate better code.
Here’s a quick walkthrough with pypi/mem0ai as example: https://youtu.be/SKZol8G_tIE
LLMs struggle with generating correct code when using lesser-known libraries or dealing with major version changes that happen after their training cutoff. With these markdowns, you can ensure that your LLM chat/coding assistants have up-to-date knowledge of the library’s API and usage patterns.
We built this using the latest Gemini models and our patchwork framework. Currently, we support npm and PyPI packages, and the deployment is optimized for speed over coverage/accuracy. Try it out and let us know if you spot any gaps or have ideas for improvement!

20. Show HN: Kameo – Fault-tolerant async actors built on Tokio
URL: https://github.com/tqwewe/kameo
Author: tqwewe
Description: Hi HN,
I’m excited to share Kameo, a lightweight Rust library that helps you build fault-tolerant, distributed, and asynchronous actors. If you’re working on distributed systems, microservices, or real-time applications, Kameo offers a simple yet powerful API for handling concurrency, panic recovery, and remote messaging between nodes.
Key Features:
- Async Rust: Each actor runs as a separate Tokio task, making concurrency management simple.
- Remote Messaging: Seamlessly send messages to actors across different nodes.
- Supervision and Fault Tolerance: Create self-healing systems with actor hierarchies.
- Backpressure Support: Supports bounded and unbounded mpsc messaging.
I built Kameo because I wanted a more intuitive, scalable solution for distributed Rust applications. I’d love feedback from the HN community and contributions from anyone interested in Rust and actor-based systems.
Check out the project on GitHub: https://github.com/tqwewe/kameo
Looking forward to hearing your thoughts!

22. Show HN: Topcast – Open-Source Alternative to Google NotebookLM Podcast Feature
URL: https://github.com/gormlabenz/topcast
Author: GromoLubbsa
Description: Google recently introduced a feature in NotebookLM that generates podcast-like audio from documents using AI. I’ve developed an open-source alternative called Topcast. It provides similar functionality but offers full control and customization.
Topcast is a Python package that converts text into audio using Text-to-Speech (TTS) and AI-generated themes like interviews and summaries. You can layer audio tracks, add background sounds, and integrate various TTS providers (Google Cloud, Elevenlabs, or Google Translate).
Key Features:
• Fully open-source and customizable • Support for multiple TTS providers • AI-generated content structures (e.g., interviews, summaries) • Flexible audio layering with fades and crossfades
Usage:
1. Input your text. 2. Select a TTS provider and an AI theme. 3. Generate audio with a few lines of code. 4. Export the result to an audio file.
Feedback and contributions are welcome!
This version is more factual, straightforward, and aligned with the minimal, engineering-focused tone that tends to resonate with the Hacker News community.

25. Show HN: Compose – Build internal tools with just back end code
Author: atul-jalan
Description: Hey HN! I’m the creator of Compose.
Compose offers Node.js and Python SDKs that let you inline components (tables, drop-downs, text inputs, etc.) and actions (file downloads, confirmation modals, etc.) into your backend functions, turning basic scripts into full web applications. These functions automatically connect to a hosted dashboard from where you can use the apps and share them with your whole team.
The main benefit of building with Compose is speed and simplicity. Compose components cleanly wrap REST endpoints, fetch calls, UI rendering, error handling, validation, and more into simple function calls that make it effortless to pass data over to the browser and get user data (e.g. clicks, form submissions, file uploads) back. Furthermore, every app comes baked in with authentication via the dashboard and analytics to track usage.
Unlike no-code, you build the apps inside your own codebase, allowing you to leverage all your existing code, keep business logic in one place, and integrate into your existing version control.
If you’re curious, I recorded a demo last night of me creating a tool to view and provision users in 5 minutes: https://youtu.be/bhI7UPeBFJo?si=wxu801-RMH9nyw_K

26. Show HN: Docs by Hashnode, we built another docs product in 2024, here’s why
URL: #
Author: fazlerocks
Description: Hey HN,
I’m not sure if this post will stick (we’re competing with some YC-backed startups in this space), but I’ll give it a try!
We built Docs by Hashnode because we saw a gap in current documentation tools. Many platforms are either too rigid, lack customization (Like ReadMe), or require too much dev time to manage (Like Docusaurus). With our docs product, we wanted to create something that’s both flexible and scalable, allowing teams to focus on creating docs without the complexity.
Here’s what we’re solving:
1. Most doc platforms don’t scale well or offer customization.
2. Teams often struggle with rigid templates and version control.
3. Companies need API references and product guides that grow with their product, not against it.
Our solution:
1. Offer both Hosted and Headless mode with GraphQL support for those who need more control.
2.Real-time collaboration with inline commenting, perfect for technical and non-technical teams to work together.
3. AI-powered search for faster, smarter discovery of docs content.
4. Unlimited API references and guides to help you scale your docs as your product evolves.
5. Create API references easily using OpenAPI specs.
6. Blazing-fast performance optimized for SEO and Lighthouse scores.
Our goal is to build documentation that evolves with your product, not something that slows you down. Some early users, including YC startups, are already using it and love the flexibility.
Would love to get your feedback or answer any questions!
Thanks for reading! Excited to hear what the community here thinks.

URL: https://minitap.io/
Author: jackbach
Description: Hey HN!
Last week I was working on a website and needed a way to synchronise visuals with live music.
I’ve used MIDI controllers for this before, but I am travelling right now and don’t have mine with me. So I had the crazy idea to build a browser extension that uses the keyboard as input and includes a sequencer. I gave myself 24 to work on it.
It ended up taking longer (of course), specially since I ended up creating a demo, a small landing, docs, and an intro video. Took me one week from idea to launch (pushed quite a bit tbh).
Features:
- Works as a browser extension. Atm distributed through chrome web store only.
– 8 customisable channels. Each channel has 3 modes: sequencer, keystroke and random.
- It sends post messages to the current page. Use however you want.
- Works with your keyboard. The key bindings are designed for expressive live usage.
- Advanced tempo controls. Easy to synchronise with live music using the ‘tap temp’ feature.
- Open Source, all code in github.
Anyway, let me know what you think.

Author: Erwanthl
Description: Hey
I’m thrilled to introduce you to my solo-founded project - Vendeo!
I created Vendeo to help businesses captivate their visitors and easily provide information about their offerings quickly and efficiently.
Today, the attention span of a website visitor is less than 15 seconds, making it challenging for businesses to fully communicate the value of their offerings. When your offer isn’t fully understood, it impacts your commercial performance.
To tackle this issue, we enable businesses to leverage the power of short videos to their advantage on their websites.
Here’s how you can benefit from Vendeo:
- Present your offer quickly and easily with our interactive video pop-ups.
- Stand out from the competition by creating a warm and unique experience.
- Assure your visitors throughout your entire sales funnel.
- And much more… the possibilities with Vendeo are only limited by your imagination.
You can add video pop-ups on any page of your website or app, offering a close, face-to-face experience that makes every customer feel valued.
With Vendeo, the core idea is simple: revolutionize customer interaction by making it more personal and meaningful.
Vendeo is completely free! You can add your first video pop-up to your website and start seeing results immediately.
We would love to connect with you, hear your feedback, your ideas, and ideally, learn how you want to use Vendeo!
Best, Erwan

42. Show HN: Soperator – Run Slurm in Kubernetes
URL: https://github.com/nebius/soperator
Author: rdjjke
Description: Hi HN,
With this operator, you can run Slurm in Kubernetes and enjoy the benefits of both systems.
Both Slurm and Kubernetes can serve as workload managers for distributed model training and high-performance computing (HPC) in general.
Each system has its strengths and weaknesses, but the trade-offs are significant. Slurm offers advanced and effective scheduling, granular hardware control, and accounting, but lacks universality. On the other hand, Kubernetes can be used for purposes other than training (e.g. inference) and provides good auto-scaling and self-healing capabilities.
It’s unfortunate that there is no way to combine the benefits of both solutions. And since many big tech companies use Kubernetes as their default infrastructure layer without supporting a dedicated model training system, some ML engineers don’t even have a choice.
That’s why we decided to merge these systems, taking a “Kubernetes-first” approach. We implemented a Kubernetes operator, which is a software component that runs and manages Slurm clusters as Kubernetes resources.

48. Show HN: Mapping policy issues with debate graphs
URL: #
Author: JamieTheJoyce
Description: When I read the autobiography of Benjamin Franklin, I encountered the phrase “in the sincere spirit of inquiry after truth” when he was describing the debates that took place at his Junto; which eventually created the first public subscription library in the U.S.
From that single phrase, I was inspired to found the Benjamin Franklin Society Library (DBA The Society Library) to seek truth on complex policy issues at the claim-level, but also create graphs of the debated claims in context. So the idea is to map out debates at the ‘societal-scale’ so we have relevant information to see various policy options and the claims that support them, to make more informed decisions based on available info possible.
>> This was a manmade graph about nuclear policy that took my team thousands of hours (excuse unprocessed/messy data): https://papers.societylibrary.org/papers/diablo_canyon/map
>> That map is also visualized in this other interactive “document” format: https://papers.societylibrary.org/papers/diablo_canyon/
>> Now we’re automating the creation of those graphs with LLMs and agentic search tools. See some progress: https://www.societylibrary.org/topics-blog/ai-alignment-supe…
We would love any and all feedback. Thank you.

Author: joegibbs
Description: This is something that I’ve been working on on-and-off in my spare time for the last few years. I started in 2020 during Covid trying to do a Mount and Blade style map in UE4, and it grew from there until where it is now - I would just add a feature, then another, until it came together. Since the start of the year I’ve really been trying to polish it some more.
I’ve got the full thing planned for a Q3 25 release.

53. Show HN: We made the first WordPress Resizer that resizes images pre-upload
URL: #
Author: vzrowan
Description: Hi HN, we (Rowan and Joerie) created Resize Control! It’s our first project together so we are really excited to show you.
Find it here: https://tuningwp.com/resize-control/#get
The Problem Working at web design agencies, we constantly faced the issue of clients uploading massive images with wrong resolutions or aspect ratios. Especially for webshops, beautiful sites were ruined by bad images. Existing plugins didn’t let us customize settings based on post type or user role.
Our Solution We built a “before upload” plugin that truly processes images pre-upload. It offers more control with features like:
Role and post-type based settings Custom size and scaling methods Background options for contained formats (great for webshops!)
Check out our free version or the pro tier. Let us know your thoughts.

55. Show HN: Pivoting to ChatGent – AI-Powered LinkedIn Tool with Guided Interviews
Author: starobrat
Description: Hey HN community, I’m excited to share my journey and get your feedback on ChatGent, a project born from a pivot. After my initial attempt at creating a chatbot builder didn’t gain traction, I decided to shift gears and focus on something new. Surprisingly, building ChatGent took much less time.
ChatGent is an AI-powered tool designed to help users create engaging LinkedIn posts.
My unique feature, the “Mini Interview,” guides users through a series of questions to develop their ideas into well-formed content. This ensures the posts truly reflect the user’s voice and expertise.
I used Python and Django with HTMX for this project. After many years of corporate Java development, I’m amazed at how fast and pleasantly this setup is for prototyping.
Thank you for taking the time to check it out. Your insights mean a lot!

56. Show HN: I made a quiz assistant powered by GPT-4o mini
URL: https://chromewebstore.google.com/detail/fakey-ai-powered-quiz-ass/jdlbndkeipfnbognkgbkggcemacaoami
Author: adibzaini
Description: Last month, I started developing a Google Chrome extension to generate fake data for web forms to help testers.
However, I decided to pivot and add a feature specifically for Google Forms that focuses on helping students answer quizzes with the help of GPT-4o mini.
A few weeks later, I added a snipping feature where you could snip an image of the quiz (not only Google Forms) and GPT4o-mini will give you the answer.
At this moment, I am adding a feature to let the users use it from a Telegram bot.
I was sceptical about building an “AI wrapper” because there is a lot of hate, especially from developers.
Oh, btw the tool is called Fakey.

Description: Hi folks,
We are soft-launching our new AI product. For the time being it is proprietary, but who knows ; ). I have a habit of impulsively open-sourcing things.
At the moment we target/accept clients from traditional industries where things are quite a bit more chaotic than most offices.

Author: Alien979
Description: I’ve just launched Cyber DNA Profiler (CDNAP), an open-source cybersecurity tool that introduces the concept of “Cyber DNA” for analyzing software, networks, and cyber attacks. CDNAP uses machine learning and graph theory to create and analyze these DNA profiles, aiming to identify patterns, predict vulnerabilities, and attribute attacks with high accuracy. Key features include Software Genome Mapping, Network Ecosystem Profiling, Attack Pattern Sequencing, and Predictive Vulnerability Analysis. The project is in its early stages, and we’re looking for contributors. Whether you’re interested in coding, testing, documentation, or just have ideas to share, we’d love your input. I’d be grateful for any feedback or suggestions from the HN community. Thanks!

65. Show HN: Using Cloudflare 1.1.1.1 DNS over HTTPS API to bulk search domain TLDs
URL: https://supersaas.dev/tools/domain-check
Author: fayazara
Description: I found out Cloudflare has a DNS over HTTPS api via 1.1.1.1 resolver, figured I’d make a small tool out of it, as somene who keeps checking domain names for side projects which I never build, this kinda helps me look for something.
It’s not fully accurate, because it returns unavailable even for parked pages, which technically are available, but works for me.
It just checks for A records via this endpoint https://cloudflare-dns.com/dns-query?name=${domain}&type=A
Just make sure to pass this header - “application/dns-json”
