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
