Clean, well-documented code with many examples, an arcade of sample games, an npm package and a yearly game jam (the third runs Oct 2 to Nov 2). Good for size-constrained jams and small web games where Phaser feels heavy. ★~4.3k.","theCatch":"Mostly a one-person project, so long-term support depends on its author. No editor or big plugin ecosystem. For larger 2D games, Phaser or Godot give you more structure.","verdict":"A lovely engine for jam-sized browser games.","addedAt":"2026-10-18","featured":false,"domain":"Libraries","subSpecialty":"Libraries","subcategory":"Game Engines","tags":["self-host","permissive","graphics-3d","active"],"capabilities":[],"surfaces":["Self-host"],"ecosystem":["Node.js"],"licenseModel":"OSS/MIT","githubStars":4303,"starsPerWeek":16,"access":"free","archived":false,"repo":{"createdAt":"2021-09-23","pushedAt":"2026-10-15","license":"MIT","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"hono","name":"Hono","tagline":"Tiny TypeScript web framework that runs on every runtime"},{"slug":"phaser","name":"Phaser","tagline":"MIT HTML5 2D game framework with scenes, physics, and tilemaps"},{"slug":"pixijs","name":"PixiJS","tagline":"MIT 2D WebGPU/WebGL renderer, not a game engine"},{"slug":"babylonjs","name":"Babylon.js","tagline":"Apache-2.0 3D engine for the web, now on v9"},{"slug":"playcanvas","name":"PlayCanvas","tagline":"MIT WebGL2/WebGPU engine plus an optional hosted Editor"}],"links":{"self":"/api/gems/littlejs","html":"/gems/littlejs","markdown":"/gems/littlejs.md","category":"/api/gems?category=libraries","categoryPage":"/stacks/libraries"}}
