Kind: Cross-platform editor and Lua game engine · License: Source-available · Last verified: 2026-09-30

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

Reach for it when:
- 2D games using Lua with an editor
- Teams targeting web, mobile, and desktop

Worth knowing: Free to use with source available under the Defold License. Its restrictions on selling the engine mean it is not an OSI-approved open-source license. Console publishing needs platform access and additional setup.
