ZenPaint, a pixel-perfect MacPaint recreation for the browser

In plain words

ZenPaint is a browser-based recreation of the original MacPaint application, built for pixel-perfect accuracy. The tool recreates classic MacPaint features including font rendering and shape tools by studying Atkinson's original QuickDraw source code and vintage hardware. Written in React with performance optimization through buffer pooling, it allows users to create pixel art and share artwork via links. The project is currently in alpha and designed for desktop use.

In the maker’s words, at launch

I've been recreating the original MacPaint in the browser on and off for a few years. It's still alpha quality, but I'm finally ready to share it more widely. The goal was pixel-perfect accuracy, so I spent a lot of time with Atkinson's original QuickDraw source code, emulators, and my iBook G3 to get details like…

  Repaint – a WebGL based website builder2024 · repaint.com · ▲236

  Hey HN! We're Ben and Izak, founders of Repaint (YC S23). Repaint is like Figma, but for creating real websites. It has panning, zooming, and dragging elements around. The settings closely follow html/css. We think an open canvas is a big improvement over other website builders. Everything is easier: styling, consistency, responsiveness… But making it work was hard! We thought HN would appreciate the tech behind it: - A custom WebGL rendering engine (w/text, shadows, blurs, gradients, & opacity groups) - A partial implementation of the css spec - A custom text editor & text shaper…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
