Hey all, I've been working on this side project to get a Cypress.io-like experience, but for Ruby developers. It's plug-n-play with Capybara system tests, with the following features: - visualize assertions/commands as they happen - view all API requests, errors, and logs in the timeline - pause/continue on any step - rewind through history with a recorded video This is brand new, so looking for people to start trying it out and leave feedback.

Hi HN! I’m Alex from Parabola (https://parabola.io). Parabola is a visual programming tool for creating functional data flows that everyone can use. It’s entirely drag-and-drop, handles data sizes much larger than a traditional spreadsheet, calculates everything live, and can run your flows on a schedule of your choosing. I used to work in strategy consulting, doing data analytics for SMBs and Fortune 500 companies. The amount of time wasted on menial tasks was astounding. Things like cleaning data, generating custom reports, creating human workflows to solve shortcomings in third…

Hi HN, I’m Kiet, one of the creators of Onlook studio. I made this app that allows you to visually edit your locally running React app and write the code back to it in real-time. The purpose is to allow you to develop UI while fully owning your code the whole time. There are other visual builders out there but they either require you to upload your code to the cloud or some lengthy setup process. Onlook runs locally, deterministically, and only requires adding a plugin for the compile step (2 lines of config change). Technical details: This is technically a web browser that can point to your…

Hey HN, I’m Kiet – one half of the two-person team building Onlook (https://beta.onlook.com/), an open-source [https://github.com/onlook-dev/onlook/] visual editor that lets you edit and create React apps live on an infinite canvas. We launched Onlook [1][2] as a local-first Electron app almost a year ago. Since then, “prompt-to-build” tools have blown up, but none let you design and iterate visually. We fixed that by taking a visual-first, AI-powered approach where you can prompt, style, and directly manipulate elements in your app like in a design…

Hey HN, I’m Kiet, and I’m one of the co-founders of Onlook – an open-sourced desktop app that lets you visually edit your locally running React app, then write your changes back to code in real time. I posted the repo a few months ago [1] when it was just 2 weeks old. Since then, we’ve made some big changes/improvements. I wanted to share some of the updates we’ve made and add more technical details. Here are the three big ones: • Inserting new elements - Draw elements in the live page like a design tool and write them back to code. • Component detection - Detect when an element is a…

Fir leverages Golang’s standard library html/template package and a bit of alpinejs to allow building reactive UIs. You start with plain old html and use alpinejs to enhance it to bring no-page-reload interactivity to web apps. The Fir toolkit is designed for Go developers with moderate html/css & js skills who want to progressively build reactive web apps without mastering complex web frameworks. It includes a Go library and an Alpine.js plugin. How it works ? On receiving user-interactions the fir server re-renders html templates and sends it over the wire where the fir client…

Hey HN, we're developing Burr (github.com/dagworks-inc/burr), an open-source python framework that makes it easier to build and debug GenAI applications. Burr is a lightweight library that can integrate with your favorite tools and comes with a debugging UI. If you prefer a video introduction, you can watch me build a chatbot here: https://www.youtube.com/watch?v=rEZ4oDN0GdU. Common friction points we’ve seen with GenAI applications include logically modeling application flow, debugging and recreating error cases, and curating data for testing/evaluation (see…

ChunkHound’s goal is simple: local-first codebase intelligence that helps you pull deep, core-dev-level insights on demand, generate always-up-to-date docs, and scale from small repos to enterprise monorepos — while staying free + open source and provider-agnostic (VoyageAI / OpenAI / Qwen3, Anthropic / OpenAI / Gemini / Grok, and more). I’d love your feedback — and if you have, thank you for being part of the journey!

For a year or two I've been building a UI library with the aim of making desktop applications fun and easy to write. It is currently written in C/Ruby and uses a custom tree sitter grammar to describe templates. Features include: composable UI components, template directives, event and prop handling, slots, styles and automation capabilities baked in. One of the goals of the project is privileging easy to write custom components via a drawing API over providing a fixed set of components. At the time of this writing it should install on Windows, Mac, and Linux, but sometimes it is hard…
