Lightpanda, an open-source headless browser in Zig
We’re Francis and Pierre, and we're excited to share Lightpanda (https://lightpanda.io), an open-source headless browser we’ve been building for the past 2 years from scratch in Zig (not dependent on Chromium or Firefox). It’s a faster and lighter alternative for headless operations without any graphical rendering. Why start over? We’ve worked a lot with Chrome headless at our previous company, scraping millions of web pages per day. While it’s powerful, it’s also heavy on CPU and memory usage. For scraping at scale, building AI agents, or automating websites, the overheads are…

In plain words
Lightpanda is an open-source headless browser written in Zig that performs web automation and scraping without graphical rendering. Built from scratch over two years and independent of Chromium or Firefox, it combines an HTTP loader, HTML parser, JavaScript runtime, and web APIs to provide a lighter, faster alternative for large-scale web scraping, AI agents, and website automation. It requires significantly less CPU and memory than traditional headless browsers.

Puck – Open-source visual editor for React2023 · github.com · ▲451Hey hackers, OP here! I've been dipping in and out of this problem space for the last few years with many of my clients. Puck sits somewhere between an old-school WYSIWYG-powered CMS and headless one, allowing content teams to author content using real React components. Traditional CMS solutions were flexible but often resulted in page that completely broke the brand guidelines. Headless CMS solutions are a fantastic way of controlling brand by restricting UI changes to developers, but makes layout changes restrictive and slow as developers often need to get involved. Puck provides a visual…
Openpanel – An open-source alternative to Mixpanel2024 · github.com · ▲244I have created an open-source alternative to Mixpanel and will explain a bit about why I decided to do this. Mixpanel is a GREAT tool and quite easy to understand (compared to GA4 and similar). I have used Mixpanel extensively for one of my React Native apps, but the last invoice was $300, which was way over my budget. I think I was paying for MTU (monthly tracked users), which was around 7000-10k users. However, a downside of Mixpanel is that it is purely a product analytics tool; you don't get any basic web analytics similar to what GA4 or Plausible offers. Therefore, I have combined the…

- TITetris in a PDF▲1,289
I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…

21st.dev▲1,211I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!
