Kontra.js is a lightweight JavaScript gaming micro-library optimized for size-constrained contexts like the js13kGames competition. It provides core game essentials such as asset loading, input handling, a game loop, sprites, object pools, and quadtrees while staying small, modular, and memory efficient.

Use cases

• build a small html5 game for a game jam
• make a canvas game under 13kb
• prototype a 2d game quickly in javascript
• load assets and handle input in a browser game
• run a fixed game loop with sprites
• use object pools and quadtrees for memory-efficient games

When to choose

• you need a tiny, size-optimized game library for js13kGames or similar size-limited jams
• you want a minimal foundation to extend rather than a full engine
• you are prototyping and want to get running quickly
• you want to combine it with other libraries

When to avoid

• you need a full-featured engine with physics, scenes, and editors like Phaser
• you are building a large commercial game needing extensive tooling
• you need 3D rendering
• you want batteries-included features out of the box
