Planck.js is a JavaScript/TypeScript rewrite of the Box2D 2D rigid-body physics engine, designed for cross-platform HTML5 game development. It provides an idiomatic JS/TS API for realistic rigid-body simulation, collision detection, and physics-based procedural animation in web and mobile games.

Use cases

• simulate 2d rigid body physics in a browser game
• port box2d physics to javascript or typescript
• add realistic collision and gravity to an html5 canvas game
• build a pinball or soccer game with physics in javascript
• run a physics engine on mobile web without native code
• make objects fall and bounce realistically in a web game

When to choose

• you want Box2D-quality 2D physics with a modern idiomatic JavaScript/TypeScript API
• you are building an HTML5 game for web and mobile browsers
• you need readable, editable physics engine source code in TypeScript
• you want a well-documented engine with many examples and an active community

When to avoid

• you need 3D physics simulation
• you are working in C++ and can use original Box2D directly
• you need a full game engine with rendering, audio, and asset management included
• you need maximum native performance outside the browser
