Matter.js is a 2D rigid body physics engine written in JavaScript for the web. It simulates bodies, collisions, constraints, and composites, rendering to canvas or integrating with other renderers.
Use cases
- simulate 2d physics in the browser
- add rigid body physics to an html5 game
- collision detection and response for javascript
- build soft bodies and cloth simulations
- physics-based interactive web animations
When to choose
- you need 2D physics in JavaScript with no native dependencies
- you want a well-documented, MIT-licensed engine with many examples
When to avoid
- you need 3D physics
- you need maximum performance for thousands of bodies in a native engine
