Mystral Native – Run JavaScript games natively with WebGPU (no browser)
Hi HN, I've been building Mystral Native — a lightweight native runtime that lets you write games in JavaScript/TypeScript using standard Web APIs (WebGPU, Canvas 2D, Web Audio, fetch) and run them as standalone desktop apps. Think "Electron for games" but without Chromium. Or a JS runtime like Node, Deno, or Bun but optimized for WebGPU (and bundling a window / event system using SDL3). Why: I originally started by starting a new game engine in WebGPU, and I loved the iteration loop of writing Typescript & instantly seeing the changes in the browser with hot reloading. After…

In plain words
Mystral Native is a lightweight runtime that allows developers to write games in JavaScript and TypeScript using standard Web APIs like WebGPU and Canvas 2D, then run them as standalone desktop applications. It combines the ease of web development with native performance, using SDL3 for windowing and events instead of requiring a full browser like Electron. The runtime supports hot reloading during development and aims to provide a consistent experience across desktop and mobile platforms.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
