Show HN: 1.2 users a day to keep the 9–5 away In my long career as an “almost digital entrepreneur” (a fancy way to say I’ve tried a thousand things online without making a single cent), I never really felt that “this is it, I’m so close, I’ll finally quit everything and update my passport: job title? SaaS founder.” (Small detail: I don’t even have a passport. But I like to imagine that if I did, I’d want something cooler than “unemployed creative” written on it). For years, I collected side projects, hobbies, half-dead MVPs, and random nonsense, all with the same ending: super hyped at the beginning, burned out in the middle, completely abandoned by the end. But a couple years ago, I decided to take things more seriously (well… I try). I started building SaaS products. Simple, fast stuff, nothing too fancy. And finally, after a long toxic relationship with perfectionism, I realized something super basic but actually powerful: I don’t need thousands of users. I just need 1.2 paying use...

Show HN: Typeconf – Dynamic Configs in TypeScript Hi! I’m the co-creator of Typeconf, an open-source tool that lets you create dynamic configs like feature flags, texts, dictionaries with features, system prompts in Typescript. My personal goal for quite a while was to bring good infra practices from big tech to open-source world. Typeconf takes care of the problem of safe deployment. Like if you have a big service and growing amount of users, you want to keep adding new stuff quickly, you don’t want to break the app, and you don’t want to spend all your time in QA. That’s where dynamic configs help! I can see that existing alternatives are kinda more focused on analytics and A/B testing, and they are not code-first and moreover, not typesafe. This gap is what we’re aiming to cover with Typeconf. https://ift.tt/lUiTNP2 April 30, 2025 at 11:06PM

Show HN: ART – a new open-source RL framework for training agents Hey HN, I wanted to share a new project we've been working on for the last couple of months called ART ( https://ift.tt/3VoTaRY ). ART is a new open-source framework for training agents using reinforcement learning (RL). RL allows you to train an agent to perform better at any task whose outcome can be measured and quantified. There are many excellent projects focused on training LLMs with RL, such as GRPOTrainer ( https://ift.tt/vEG3M4Q ) and verl ( https://ift.tt/ZCyq3Xv ). We've used these frameworks extensively for customer-facing projects at OpenPipe, but grew frustrated with some key limitations: - Multi-turn workflows, where the agent calls a tool, gets a response, and calls another, are not well supported. This makes them a non-starter for any task that requires an agent to perform a sequence of actions. - Other frameworks typically have low GPU efficiency. They may require multiple H100 GPUs just to trai...

Show HN: Auto-fix your GitHub PR issues with Proton for FREE Hey HN! We just launched Proton, a GitHub app that listens to PR review comments and suggests code changes to address them. It creates a new PR based on top of your working branch, so you can simply review and merge. How is it different from other AI code review tools? Others focus on pointing out issues, whereas Proton focuses on addressing them. Although some of them can also suggest fixes, they tend to only work on nearby lines or within a single file. But real-world feedback often involves cross-file changes like “Let’s extract this to a separate component”, or “We should follow the same pattern of doing things in file X, Y and Z”. Proton has full repo context, so it can handle these kinds of feedback. Want to see it in action? Here’s a short demo: https://youtu.be/zDEfw-R2jWc , and there’s the PR shown in the demo video: https://ift.tt/xNFhPcp It’s free, takes two clicks to install, and works out of the box. Here’s the i...

Show HN: Beatsync – perfect audio sync across multiple devices Hi HN! I made Beatsync, an open-source browser-based audio player that syncs audio with millisecond-level accuracy across many devices. Try it live right now: https://ift.tt/XO4bSKF The idea is that with no additional hardware, you can turn any group of devices into a full surround sound system. MacBook speakers are particularly good. Inspired by Network Time Protocol (NTP), I do clock synchronization over websockets and use the Web Audio API to keep audio latency under a few ms. You can also drag devices around a virtual grid to simulate spatial audio — it changes the volume of each device depending on its distance to a virtual listening source! I've been working on this project for the past couple of weeks. Would love to hear your thoughts and ideas! https://ift.tt/PbJm7Wo April 30, 2025 at 12:32AM
