Know what's in the toolbox

3D rendering library

The most widely used JavaScript 3D library: scenes, cameras, lights, materials, and loaders over WebGL, with a WebGPU renderer alongside. It renders; physics, input, and game structure are up to you.

React renderer for Three.js

Write Three.js scenes as declarative React components. Pairs with the drei helper library for cameras, controls, loaders, and effects.

3D web engine

A full 3D engine started at Microsoft, with physics, a scene inspector, PBR lighting, WebXR, and WebGPU support built in.

3D game engine and editor

A WebGL/WebGPU game engine with a collaborative, browser-based visual editor. Games are built for the web first, with small builds that load fast on mobile.

2D game framework

A full 2D framework for browser games: scenes, sprites, tilemaps, input, audio, cameras, and built-in physics. The default choice for 2D HTML5 games.

2D rendering engine

A fast 2D renderer for WebGL and WebGPU. It draws sprites, text, and graphics very quickly but isn't a game framework — no built-in physics or scene flow.

Beginner-friendly 2D library

A small, fun-first JavaScript game library with a component-based API that gets a playable game on screen in a few lines. The community-maintained continuation of Kaboom.js.

Full game engine

A complete, MIT-licensed 2D and 3D engine with its own editor and scripting language (GDScript), plus C#. Exports to desktop, mobile, and the web.

Gradually typed scripting language derived from Lua

A language derived from Lua 5.1 with optional type checking, used for gameplay scripting in Roblox. Its language implementation is open source independently of the Roblox platform.

Visual novel engine

A story-focused engine with dialogue scripting, branching, screen language, saves, and Python for custom logic.

Lua framework for 2D games

A Lua framework supplying graphics, audio, input, and physics while leaving game structure and tools to the developer.

Physics engine

A 2D and 3D physics engine written in Rust and shipped to JavaScript as WebAssembly. Deterministic simulation, rigid bodies, joints, and character controllers.

Tilemap level editor

A free desktop editor for tile-based levels. Exports JSON and TMX maps that Phaser, Godot, and most 2D engines can load directly.

C# game framework

A code-first .NET game framework with graphics, input, audio, and a content pipeline. The team supplies game structure and authoring tools.

C game programming library

A compact C library providing windowing, drawing, input, audio, and 2D/3D APIs. You own the game loop and application structure.

Java game framework

A Java game framework with platform backends, rendering, input, audio, and asset handling. Shared game code still needs target-specific testing.
