What is Defold?

Defold is a free game engine that gives developers a single editor for visual scene building, code editing, particle effects, and asset management. Games are scripted in Lua, with an integrated debugger and support for native extensions when lower-level code is needed. Defold emphasizes a small engine footprint and fast iteration, with hot reload and a built-in profiler for tuning performance. Games built with Defold can be exported to Windows, macOS, Linux, iOS, Android, HTML5, Steam, PlayStation 4/5, Nintendo Switch, and platforms like Facebook and Poki, with Xbox support listed as coming soon. The engine is free to use with no licensing fees or runtime royalties.
