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.

Editor and publishing platform for Roblox experiences

An integrated editor for building worlds, scripting in Luau, testing multiplayer behavior, and publishing experiences to Roblox.

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.

Editor-led 2D game engine

A 2D engine with rooms, sprites, object events, GML scripting, and platform export tools.

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.

Browser-based game editor with visual events

A game editor centered on layouts, objects, event sheets, and behaviors, with optional JavaScript scripting.

Map-and-event editor for 2D RPGs

An RPG editor with tile maps, a game database, event commands, built-in combat, and JavaScript plugin extensions.

Cross-platform editor and Lua game engine

An editor and runtime built around game objects, components, collections, Lua scripting, and a cross-platform build pipeline.

Cross-platform game engine

A widely used commercial engine for 2D and 3D games, scripted in C#, with a large asset store and export to desktop, mobile, consoles, and the web.

High-end 3D game engine

Epic's engine for high-fidelity 3D, with C++ and Blueprints visual scripting, and built-in rendering features like Nanite geometry and Lumen lighting. Also used for film and visualization.

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.

Free game asset library

Thousands of CC0 2D sprites, 3D models, UI elements, and sound effects you can use in any project, commercial included, without attribution.

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.
