## What it is
Nidium is a hardware-accelerated rendering engine written in C++ for building apps and games with JavaScript, embedding Mozilla's SpiderMonkey engine, Google's Skia graphics library, and Facebook's Yoga layout engine. It exposes web-like APIs (Canvas 2D, WebGL, WebSocket, HTTP, module loading) in a lightweight standalone runtime for desktop and mobile, plus a server-side variant.

## Use cases
- build 2d games with javascript and canvas
- create cross-platform mobile apps with hardware-accelerated rendering
- run three.js or pixijs outside a browser
- prototype web-like apps without electron or webkit
- write javascript apps with tcp udp and http sockets
- embed a lightweight javascript runtime with canvas rendering

## When to choose
- you want a small (~20MB) standalone JavaScript runtime with Skia-accelerated 2D/WebGL rendering
- you need web-like canvas APIs without a browser engine dependency
- you target Linux, macOS, or Android including low-power devices like Raspberry Pi

## When to avoid
- you need Windows support, which is not implemented
- you need app packaging and distribution, a listed missing feature
- you need an actively maintained project - the last release was in 2019
- you need production-grade documentation
