5. Show HN: AI-powered code summaries for team leaders and founders
Author: RaulOnRails
Description: I work as a part-time programmer at Gumroad. At the beginning of September, I came back from a three-week long vacation, and a lot has changed at work. Both in terms of how much stuff was shipped and how we do things internally.
Everybody switched to using Cursor for development, and productivity skyrocketed. I gave it a try, and the first thing I asked the chat was to give me a summary of the highlights that shipped while I was gone, and it came up with a pretty decent output (https://x.com/RaulOnRails/status/1830580206178070932). This was basically the spark that made me build Git Digest.
It’s a simple tool that uses OpenAI’s chat completion to read daily code commit diffs and give you a summary of what the team has shipped. Let me know what you think.

11. Show HN: Golance – Cheaper Alternative to Upwork
URL: https://golance.com/staff-augmentation
Author: dannydanscott
Description: Hi hackers,
Dan here, one of the founders of goLance (https://golance.com). We’re trying to make freelancing and hiring remote talent as seamless and beneficial as possible for both freelancers and clients.
Finding the right talent or projects, managing payments, and ensuring quality work can be challenging in the freelance world. Many platforms take large cuts from freelancers’ earnings, have slow payment processes, or lack transparency in their operations. These issues can lead to frustration for both freelancers and clients, hindering productivity and growth.
I worked in the tech industry for several years, experiencing firsthand the challenges of finding and managing remote talent. The existing platforms often felt clunky, expensive, and not always aligned with the needs of either freelancers or clients. This led to inefficiencies, missed opportunities, and sometimes even project failures.
Our solution at goLance addresses these pain points. We take only 10% from freelancers, compared to Upwork’s 20%. Freelancers get paid within 24 hours of job completion, not 5-7 days. Our algorithm for job matching and freelancer rankings is open and clearly explained, promoting transparency. We offer 24/7 live chat support for both clients and freelancers, ensuring help is always available. Our time tracking tool, goMeter, offers advanced functionality like video snapshots and activity levels. And we have a rigorous vetting process for freelancers to ensure high-quality talent on the platform.
What sets us apart is our commitment to creating a fair and efficient marketplace. We believe that by reducing fees, speeding up payments, and providing better support and tools, we can create a more positive experience for everyone involved in the freelancing ecosystem.
We’ve been growing steadily since our launch in 2015, with over 1 million freelancers now on the platform. Our goal is to revolutionize the way remote work is facilitated and managed.
If you’re a freelancer or a client looking to hire, we’d love for you to try out goLance. You can sign up and explore the platform at https://golance.com. If you have any questions or need assistance, our support team is always ready to help.
We’re eager to hear your thoughts and experiences with freelance platforms. What challenges have you faced? What features do you think are missing from current solutions? If you have any interesting stories about your freelancing experiences, good or bad, we’d love to hear those too.

12. Show HN: Giving an AI Agent a Wallet
URL: https://www.youtube.com/watch?v=wQ9rf5HtuhQ
Author: pol_avec
Description: We’ve been exploring the intersection of AI and internet-native payments. Here’s a demo of what we’ve built:
Our agent starts out pretty basic - it can chat, but can’t access the internet. Then we give it a lightning wallet.
This simple addition, combined with the L402 protocol, opens up new possibilities:
1.The agent can now pay to use external tools
2.It accesses a web scraping service protected by L402
3.It scrapes web content and summarizes it
4.You can watch its wallet balance change in real-time
L402 is key here. It’s a protocol that implements internet-native paywalls, allowing for seamless, programmatic payments.
We’ve put together a short video demonstrating this process: https://youtu.be/wQ9rf5HtuhQ
For those interested in the technical details, we’ve open-sourced the code: https://replit.com/t/fewsats/czjf93/repls/Web-Scraping-Agent…
Key components:
AI agent: A large language model with chat capabilities
Wallet: Lightning Network integration for payments
L402 protocol: Enables internet-native paywalls
External tool: A web scraping service protected by L402
User interface: Shows the agent’s thoughts and wallet balance
This demo shows an AI agent using one pre-integrated L402 tool. Next, we’re working on agents that can discover and use any L402 tool on the fly. What possibilities do you see in this approach?

13. Show HN: My microkernel-based OS built from scratch now has basic Unix commands
URL: https://github.com/lux-operating-system/kernel
Author: jewelcodesxo
Description: This project contains no code from Linux, BSD, Minix, or any other OS. Everything up until this point is written entirely from scratch, including a pure microkernel (that only implements multiprocessor priority scheduling, memory management, and interprocess communication), a work-in-progress implementation of the standard C library, and a variety of servers that provide drivers and other essential OS functionality.
At the time of writing this post, the servers provide drivers for the keyboard, NVMe SSDs (that works on real hardware), a Unix-like virtual file system (with a single root mountpoint, /dev, /proc, etc.) and several other necessities. The main goal of this project is to research OS design and try to overcome some of the performance penalties associated with microkernels, while also building a general-purpose usable Unix-like OS on top of it. It’s also intended to make the study of OS development and theory a little more approachable through self-documenting, clean, and readable modular code.

14. Show HN: Parliament Wow makes sense of UK democracy
URL: https://parliament-wow.threepointone.workers.dev/
Author: mattzcarey
Description: Over the weekend we built Parliament Wow. It’s hacky, buggy and slightly broken but it does the job :)
Parliament Wow makes it easy to find out what is going on in parliament and what it actually means for you and me.
We know that nobody has the time to watch hours of debates, drown in legal paperwork or keep up with the implications of every vote. Not me or you and least of all your MPs. There is just too much data.
So we made a solution. We paired some semantic search with every publicly accessible document, audio recording or transcript we could get our hands on + some generative models to make it all look pretty. And we built a demo of what democracy could become.
Parliament Wow won the a16z London Hackathon in the Build Back Britain category.
Where should we go with this?

16. Show HN: Winamp and other media players, rebuilt for the web with Web Components
URL: https://player.style
Author: Heff
Description: Hey all, creator of Video.js and co-founder of Mux & Zencoder here. My team and I built this. I hope you like the themes we’ve built so far, and maybe even get inspired to build your own.
I know Web Components are in a bit of a drama cycle right now. I’m happy to see them get any attention really. I’ve been pretty bullish on them since ~2013 when I started working with them, at least in the context of a widget like a video player. I’ve even given many related talks on them like this one (https://www.youtube.com/watch?v=N6Mh84SRoDg).
I would never push them for a large app or as a full replacement for React, but they’ve been incredible for making video players that are compatible across many contexts, and Player.style is a clear demonstration of that when you get to the step of embedding a theme. Web components really shine for building bits of UI that can be shared between projects. They also are the best way to avoid the long term JS framework thrash that’s a challenge for any developer who works on the web for long enough. One of the best decisions I ever made for Video.js was to not build it with jQuery. Video.js is 15 years old now and still in use, while all the jQuery players are not.
For some added context of this project, when I was building Video.js back in 2010 I put a lot of thought into how other developers would customize the player controls. I was excited to use web technologies (instead of Flash) to build a player and I knew other web devs would be too.
Fast forward 14 years — Video.js has been used on millions of websites including Twitter, Instagram, Amazon, Dropbox, Linkedin and even in United Airlines headrests. In 99.99% of those cases the default Video.js controls were used with little to no customization. So…huge adoption success, utter failure in sparking creativity. In retrospect, asking people to learn a new UI framework just to style their player was too much.
Media Chrome and Player.style are my answer to that friction.
- Media Chrome - A suite of Web Components and React Components that let you easily build a media player UI from scratch, using components you’re already familiar with.
- Player.stye - Themes built with Media Chrome, showing the cross-player and cross-framework flexibility of Media Chrome
Media Chrome is already used on sites like TED.com, Syntax.fm, and anywhere the Mux Player is used. We’ve spent the last few months building some great themes for Player.style. I probably had the most fun recreating the Youtube icon animations from scratch using SVGs and CSS. (Whoever made the originals, nicely done!)
It’s all free and open source, so don’t hesitate to jump in if you’re interested in the project. And of course I’m happy to answer any questions.

26. Show HN: My 6-Year Journey to Building a Social Media App from Scratch
URL: https://stages-official.com/
Author: benni97
Description: In 2018, after completing my computer specialist training and just before starting university, my best friend and I came up with the idea for a social media app. We were driven by our frustration with how major platforms prioritize profits, often at the expense of user experience. These platforms have increasingly cluttered user feeds with ads, reducing the visibility of content that users genuinely follow and are interested in. This shift seems designed to keep users scrolling longer, not necessarily more meaningfully engaged. We felt this could be approached differently, aiming to build something more community-focused, free from external investor pressures.
One of the key features of the app is its focus on discovering local events and spots, which is particularly handy for users who are traveling or looking to explore their own city more deeply. This feature supports offline community engagement by encouraging users to meet up and share experiences.
I chose Flutter for development to ensure a consistent and efficient user interface across both Android and iOS devices. Keeping up with Flutter’s updates over the years demanded continuous adaptation and optimization to maintain high performance.
For the backend, I used AWS and leaned heavily on its serverless offerings like Lambda, API Gateway, and DynamoDB for data storage. I managed user authentication with Cognito, which, despite initial challenges, now runs smoothly thanks to several workarounds. The backend was built to be scalable and resilient, using an active-active multi-region setup through Infrastructure as Code, which allows me to expand to new regions quickly as needed.
After six years of sustained effort, the app has launched. It operates without ads or premium fees and includes features that facilitate user connections around shared interests and local events.
I’m keen to get your feedback and insights on how we can continue to refine and expand our app’s features. For those interested, I’m also happy to discuss more about the technical challenges and solutions I encountered.
Thank you for taking the time to read about my experience. It’s been a long road, and being able to share this moment with you means a lot to me. If you’re a fellow developer or someone dreaming of starting your own project, I hope my story shows that with enough determination, you can turn your ideas into reality, step by step. It’s not easy, but it’s definitely possible, and every small step counts.

34. Show HN: My friend’s son thought he was Peter Pan, so I built him an app
URL: #
Author: myab
Description: My buddy’s kid, Francisco, is obsessed with Peter Pan. It’s adorable, but it got me thinking… what if Francisco could actually see himself in Neverland?
This gave me the idea to build an app that could take any child’s photo and drop them right into their favorite storybook. After a year and the magic of Stable Diffusion (thanks, ComfyUI!), MyStorybook was born.
Here’s how it works:
1. Choose a story: We have a library of engaging children’s stories, including classics like Peter Pan. 2. Upload a photo: I uploaded a photo of Francisco, and our AI seamlessly integrated him into the story’s illustrations. 3. Record your voice: ElevenLabs’ voice cloning is insanely good - it makes the whole experience incredibly personal by using your own voice for the narration.
Francisco’s reaction? Priceless. Seeing his face light up as he flew alongside a very familiar-looking Peter Pan… well, let’s just say there might have been some real-life pixie dust in the air that day.
Right now, MyStorybook is live on the App Store and Google Play. There are a few stories to try, and we’re adding more all the time.
Since we’re avid Hacker News users, we created a promo code just for the community! The next 20 people who use the code HN at checkout can personalize a story for free.

35. Show HN: Tool that auto-extracts debug data from user support chats
URL: #
Author: thedg
Description: Hey HN! 4 years ago, an ex-Cloudflare team and I started building Jam.dev –– trying to make bug reporting a lot less painful.
It’s crazy that in 2024, the state of the art way to debug a reported issue is to hop on a call. How is there no tooling?!
So we built a tool we needed back at Cloudflare: fast forward to today and it’s used by 150k people all over the world.
But it still only solved when PMs or QA reported bugs to engineers. We still hadn’t quite figured out how to help users –– usually the worst bug reporters of them all –– report bugs better.
There are tools out there for session recording, but then to find the exact moment you need, you need to scrub through a 45 min video of someone’s entire session. It’s 1) creepy 2) not efficient.
So we kept thinking.
Earlier this year, an engineer on our team prototyped something we could use in our own customer support chats. It’s a plugin that lets support agents request a screen recording (with dev logs) from the customer.
As we started to use it ourselves, we realized it was saving us from having to hop on calls with customers and ask them a lot of questions to figure out what was happening.
While recording, we automatically capture:
- Console logs
- Network requests (fully inspectable, w/ copy as cURL for local repro)
- Timing waterfall
- Session metadata (User ID, etc) & system status (battery, etc)
- Device/browser/OS info
There’s some extra debug tooling in there for websockets and graphql too (we love/hate graphql, but that’s besides the point.)
You can see an example of what the captured data looks like here: https://jam.dev/c/cff872c4-0a40-4bc2-a35a-9623cc4926a6
It’s a lot more private than the session recording tools out there because it’s only recording when the user explicitly starts/stops the recording, and not the full session.
I hope you’ll check it out and let us know what you think: jam.dev/customer-support
The worst part of debugging customer issues is not even the debugging, it’s just figuring out what the user is even talking about. It’s so crazy that there’s not much tooling out there to make that a lot faster, even in 2024. We really want to build something that makes this part of the job suck less, and we’d love to know what you think and how we can make it even better.
My email is [email protected], feel free to reach out anytime.
By the way, we’re hiring engineers and if making debugging a lot more efficient is a problem that excites you, we’d love to chat: jam.dev/careers

Description: I have used a lot of habit-tracking apps and most of them are filled with features that are not useful to me, sometimes UI is a mess etc. I wanted to build an app that was simple and useful. I wasn’t sure about GPT ability but wanted to give it a try. There was a lot of trial and error, especially in figuring out the logic of the streak counter, which took a lot of time. I have spent some time polishing the UI as well. Although not a perfect app, I think I have a good tracker. I am planning to add more features and would love to know your thoughts and feedback.

URL: https://blog.eriksen.com.br/en/introducing-kotlin-money
Author: eriksencosta
Description: Manipulating monetary amounts is a common computing chore. However, no mainstream language has a first-class data type for representing money, it’s up to programmers to code abstractions for it. This isn’t an issue per se until dealing with rounding issues from operations like installment payments (e.g., buy now, pay later), foreign exchange, or even simple things like fee processing and tax collection.
Inspired by my days at N26 Brasil dealing with these challenges, I introduce Money: a Kotlin library that makes monetary calculations and allocations easy.

40. Show HN: KaibanJS – JavaScript Framework for Building Multi-Agent Systems
URL: https://www.kaibanjs.com/
Author: darielnoel
Description: Hey HN,
A couple of friends and I spent the last three months working on KaibanJS, an open-source framework for building AI multi-agent systems.
Honestly, we’re not 100% sure it’s fully ready for launch. But we’d love to get your feedback on it.
The idea came from us trying to find a native JS solution for working with AI agents, and we couldn’t find anything that really fit well with the JS ecosystem… stuff like React, Next, State management, etc. So, we decided to build it ourselves.
Because KaibanJS runs in the browser, we also built a cool UI—a Kanban board, kinda like Trello, that lets you visualize your agents as they work. It’s much better than having to look at AI agent logs in the console ;)
KaibanJS is designed to make working with agents easier for JS devs, without dealing with all the low-level stuff, but it’s flexible enough to handle more complex setups if needed. (We even use LangChain behind the scenes for some of the orchestration.)
We’re excited to hear what you think, and any feedback would be super helpful.
Thanks in advance

43. Show HN: A founder-friendly business finance tool – Nuvio
Author: ali_ilhami
Description: Hi HN,
I’m Ali, one of the co-founders of Nuvio, an AI-driven financial tracking and analysis tool designed specifically for startups and small businesses. Like many founders, we struggled with scattered financial data and messy Excel sheets in our previous projects. So we set out to build something simple yet powerful—especially for teams that don’t have a dedicated finance team or find existing accounting tools too complicated.
Nuvio helps with:
- Detailed income/expense tracking with automated dashboards
- Cash flow tracking and projections (us bank integrations coming soon)
- Product/project-based financial analysis
We recently launched on Product Hunt and now have users in 10+ countries!
Additionally, we’ve introduced an AI assistant (currently in private beta) that works similarly to ChatGPT, but is tailored to your business’s financial data. If you’d like early access, you can sign up using this link -> https://tally.so/r/w2vd29
We’d love to hear from fellow founders and get your feedback. What financial challenges do you face? How do you currently track and manage your finances? I’m here to answer any questions or dive deeper into our journey!

47. Show HN: Simplifying Patient Intake via Mobile in Developing Countries
Author: vincentxplore
Description: Hey HN,
I’m a founder working to solve a problem many healthcare providers face, especially in developing countries—collecting patient intake information easily and securely, all from a mobile device.
That’s why I built Formisoft.com. It allows clinics and healthcare providers to quickly create intake forms, even on mobile phones, making it accessible where mobile usage is the norm. With AI-powered form generation and built-in compliance, Formisoft simplifies patient intake while ensuring data security.
I’d love to hear your feedback!

48. Show HN: Cloud Development Environment Using Gaming CPU – Codespaces Alternative
URL: #
Author: lyang2821
Description: A few months ago I started my journey to bootstrap Lapdev[1], an open core solution to manage remote development environments that you self host. It didn’t really work out.
Still I was developing Lapdev on a AMD Desktop CPU machine hosted in Hetzner, because I know it’s more performant and less expensive than a public cloud. And it strikes to me that all existing cloud dev env providers like Codespaces and Gitpod all use the cloud, i.e. server CPU for their offering. So I quickly did some performance tests on Codespaces and Gitpod, and comparing them to my AMD box. Unsurprisingly, my AMD box can deliver 2x the performance, given the same CPU cores.
So it’s clear to me that I should work on a cloud dev env with AMD high end gaming CPUs, as there’s no such offering on the market. If you’ve got remote development in your workflow, check us out on https://lap.dev/ and see if it can boost the performance for you.

49. Show HN: Boost your warm intros with an AI that finds you the perfect investors
URL: https://easyvc.ai/
Author: daolm
Description: After raising +$4M for my last startup, I’ve been coding for the last 6 months EasyVC to skip most of the annoying tasks behind fundraising from investors.
- It takes your startup’s description and matches it against several data points of each investor of the database (VCs and Business Angels), such as investment thesis, portfolio companies, investment stage, etc.
2. It gives you all the contact details of the investor, including verified emails and LinkedIn profiles.
3. It suggests the founders of the portfolio companies you should reach out to along with their LinkedIn profiles, in order to get warm intros.
This is for any tech founder raising from pre-seed to series A, of any industry.
Hope you like it, and would love to hear any questions/feedback/comments! :D

55. Show HN: Blockchain Explorer Detector – Auto-detect and open the right explorer
URL: https://usdtqrtool.com/detect-blockchain-explorer
Author: moonbay42
Description: I’ve created a tool that automatically detects the blockchain network of a given address and redirects you to the appropriate blockchain explorer: https://usdtqrtool.com/detect-blockchain-explorer
As someone who frequently works with multiple blockchain networks (primarily Ethereum and Solana), I found myself constantly switching between different blockchain explorers. The process of Googling the correct explorer URL and then inputting the address was time-consuming and tedious.
This tool aims to streamline that process. Simply input any blockchain address, and it will automatically open the corresponding explorer page. Currently supported networks include:
- Ethereum
- Binance Smart Chain
- Bitcoin
- Tron
- Cardano
- Solana
Key features:
- One-click exploration for addresses across multiple networks
- Time-saving for developers and users working with multiple blockchains
- Simple, clean interface
In addition to the Blockchain Explorer Detector, the website offers other useful USDT tools:
- [USDT QR Code Generator](https://usdtqrtool.com): Generate QR codes for USDT addresses for easy transfers.
- [USDT Converter](https://usdtqrtool.com/usdt-converter): Convert and calculate USDT to other currencies easily.
- [Random Coin Generator](https://usdtqrtool.com/random-coin): Generate random cryptocurrency addresses and private keys.
- [Top 100 Crypto Exchanges](https://usdtqrtool.com/top-crypto-exchanges): View information on the top 100 cryptocurrency exchanges.
- [USDT QR Code API](https://usdtqrtool.com/api-docs): API documentation for displaying USDT QR codes in terminal.
All these tools are free and designed to provide a comprehensive online toolkit for USDT users.
I’d love to hear your thoughts, suggestions, or ideas for improvement. What other features would make these tools more useful for you?
