Native WebGPU JS runtime with SDL3

What it solves

Mystral Native.js is a lightweight runtime that allows developers to build native desktop applications using JavaScript or TypeScript and Web APIs, specifically targeting games. It eliminates the need for a full web browser (like Chromium in Electron) while providing native WebGPU rendering for high-performance graphics.

How it works

It acts as a native runtime that maps familiar Web APIs (WebGPU, Canvas 2D, Web Audio, and fetch) to native system libraries. It uses a JavaScript engine (V8, QuickJS, or JSC) and a WebGPU implementation (Dawn or wgpu-native) to execute code and render graphics directly on the hardware across macOS, Windows, and Linux.

Who it’s for

Game developers who want to use web-standard APIs and JavaScript/TypeScript to create high-performance native desktop games without the overhead of a browser.

Highlights

  • Browser-less Execution: Runs JS/TS code natively without Chromium, reducing resource overhead.
  • WebGPU Support: Full support for native WebGPU rendering for advanced 3D graphics.
  • Cross-Platform: Works on macOS, Windows, and Linux, with embedding support for iOS and Android.
  • Standalone Binaries: Ability to compile games into single, dependency-free executables.
  • API Compatibility: Supports Canvas 2D (via Skia), Web Audio, and TypeScript (via SWC).

    WelsonJS is a Windows‑only framework that lets you write console or GUI desktop apps with JavaScript (and TypeScript, CoffeeScript, etc.) using the built‑in Windows Script Host engine. It runs without extra runtimes, supports legacy Windows versions, bundles many libraries (jQuery, Monaco, React, ESENT DB, native Windows service APIs), and includes optional LLM integrations (ChatGPT, Gemini). Apps can be packaged as zip files, Inno Setup installers, or simple copy‑and‑run bundles, and a PowerShell bootstrap script can pull the runtime automatically.
