Defold is a free, source-available, cross-platform game engine for building 2D and lightweight 3D games for desktop, mobile, web, and console targets. It bundles a visual editor, Lua scripting runtime, build pipeline, debugger, and profiler into a single turn-key toolchain with no royalties or licensing fees.

Use cases

  • build a 2d mobile game for ios and android
  • make an html5 browser game
  • create a cross-platform game with one codebase
  • learn game development with lua
  • ship a lightweight 3d game
  • prototype a game quickly with hot reload
  • publish a game to steam or consoles

When to choose

  • you want a free, production-ready engine with no royalties
  • you target mobile or web games, especially 2D
  • you prefer Lua scripting with an integrated editor and debugger
  • you need a small engine footprint and fast builds

When to avoid

  • you need heavyweight AAA 3D tooling and pipelines
  • you prefer C# or visual scripting over Lua
  • you need a huge third-party asset/plugin ecosystem like Unity's
