LittleJS is a tiny, fast, open-source HTML5 game engine written in JavaScript with no dependencies. It bundles WebGL2/Canvas2D rendering, arcade and Box2D physics, particles, spatial audio, and input handling in a very small footprint.

Use cases

• build a 2D browser game
• make a game for js13k size-coding competition
• create a mobile-friendly HTML5 game
• add particle effects and shaders to a web game
• prototype a game with arcade physics
• build a game with Box2D physics in the browser
• make a game jam entry quickly

When to choose

• you need a lightweight, dependency-free 2D game engine for the web
• you're entering size-limited competitions like JS13k
• you want fast WebGL rendering with a simple API
• you need built-in sound generation, input, and physics out of the box

When to avoid

• you need a full-featured AAA-grade engine with editors like Unity or Unreal
• your project is primarily 3D and needs a full 3D engine (Three.js support is only a plugin)
• you need console or native platform targets
