Products that do what ZenPaint, a pixel-perfect MacPaint recreation for the browser does
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 font rendering and the shape tools exactly right. Some technical notes: - Font rendering was surprisingly tricky; understanding the original pipeline's quirks took lots of experimentation, and avoiding canvas smoothing/aliasing required careful handling. - Written…

It requires no registration, no installation, and no configuration. Just run it on any computer and start drawing freely.

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…

https://lisagui.com/info.html This is a web OS I wrote in vanilla JS that looks like the Apple Lisa Office System (1983-85), with other contemporaneous influences and additional improvements and features. It's currently in alpha and isn't remotely bug free. I had been holding off on posting this here until it was somewhat presentable and useful. Please note; the Lisa conforms more literally to the desktop metaphor than most modern GUIs - some of the important differences are mentioned in the readme. This is a complete recreation of the UI in JS; it all renders to a single…

There are lots of glassmorphism generators out there, but I wanted to push the effect further! This project is the result of months of experimenting with CSS property layering and battling browser quirks. Cross-browser compatibility is actually the reason I rely on ::before and ::after pseudo-elements to build up the effect. Move the color/opacity to the main element, and you’ll get weird color bleed on the corners in Chrome. Move the texture, and it muddles the bevel’s specular highlight. Move the bevel, and it gets blurred out by the backdrop-filter. And so on! Layers include: *…

I'm working on a pure js webgl image editor with effects, filters, crop & perspective correction, etc. My goal is to give the community an opensource solution as unfortunately most comparable apps are closed sources. https://mini2-photo-editor.netlify.app to try it out (https://github.com/xdadda/mini-photo-editor)

Hey Everyone! I wanted to show my passion project I made a few years back and recently turned into a web app. Airdraw is an app that takes in your hand gestures and converts it into real time drawing capabilities. There are tons of stuff I want to build with this, but most importantly just put it out into the world! Hope you all enjoy :) Tested on my MacOS with Chrome, Safari, and FF I included a link to the original GH project I wrote here - https://github.com/arefmalek/airdraw and a link to the blog where I explained how I made it here -…

Hey HN! I want to show my new open-source project ArtistAssistApp. ArtistAssistApp - the web app to paint better with ease. Tools for realistic color mixing based on real paints, tonal value drawing, simplified sketching, and more. Import your own photos, select any desired color directly from the image, and learn how to mix it with your paints. The web app provides a step-by-step guide on how to precisely mix that color using your own paints using atomic or optical mixing. Atomic mixing is the physical mixing of colors together, while optical mixing is the result of placing a transparent…

Creating high-quality scientific figures can be time-consuming and challenging, even though sketching ideas on paper is relatively easy. Furthermore, recreating existing figures that are not stored in formats preserving semantic information is equally complex. To tackle this problem, we introduce DeTikZify, a novel multimodal language model that automatically synthesizes scientific figures as semantics-preserving TikZ graphics programs based on sketches and existing figures. We also introduce a Monte Carlo Tree Search-based inference algorithm that enables DeTikZify to iteratively refine its…

I built React Photo Studio, a free image editor that runs entirely in the browser with React and WebGL. Right now only the brush tool is functional for drawing, while the rest of the interface is a prototype awaiting development. Everything is client side, no backend. I would appreciate feedback on usability and code structure, and I welcome pull requests. Live demo https://reactphotostudio.app Code https://github.com/chase-manning/react-photo-studio

Looking at websites such as Clerk, I began thinking that design engineers might be some kind of wizards. I wanted to understand how they do it, so I started reverse-engineering their components out of curiosity. One thing led to another, and I ended up building a small library of reusable, animated components based on what I found. The library is built in React and Framer Motion. I’d love to hear your feedback

Hello internet folks! I'm happy to share the first TestFlight release of Glyph3D, a 3D text visualizer for macOS and iOS. It's free, supports pretty much any utf8 data, and is a pretty interesting way to navigate your repositories or data directories without the limitations of standard text windows! Download and bookmark for macOS and iOS: https://github.com/tikimcfee/LookAtThat/ - You should be able to download public repos from GitHub and render them. - Play with opening and closing windows. I've disabled many of the in-flight features to keep user confusion down,…

Hello HN! I want to share something me and a few friends have been working on for a while now — Zeroshot, a web tool that builds image classifiers using text-image models and autolabeling. What does this mean in practice? You can put together an image classifier in about 30 seconds that’s faster and more accurate than CLIP, but that you can deploy yourself however you’d like. It’s open source, commercially licensed, and doesn’t require you to pay anyone per API call. Here's a 2 minute video that shows it off: https://www.youtube.com/watch?v=S4R1gtmM-Lo How/why does it…

Pablo is a Chrome extension that copies the HTML and CSS behind any element you hover. It captures computed styles, fonts (with @font-face and Google Fonts links), CSS keyframes, and animation props from GSAP and Framer Motion. The output is structured so it pastes cleanly into Claude Code, Cursor, or Codex when you want to rebuild a component in your own stack. Manifest v3, no host permissions, no backend. Free. https://usepablo.dev Happy to answer questions about how the extraction works, and would love to hear about sites where the output breaks.
