In their own words
Defold
Defold is a game engine for building cross-platform 2D and 3D games. Its toolchain combines an editor, runtime, scripting workflow, build pipeline, and deployment flow. Game logic is written in Lua; native extensions can use C, C++, Objective-C, Java, or JavaScript. Visual editors, a debugger, profiler, particle effects, animation, and integrated 2D and 3D physics are included. Target platforms listed are Windows, macOS, Linux, iOS, Android, HTML5, PlayStation 4, PlayStation 5, and Nintendo Switch. Integrations include Firebase Analytics, AdMob, in-app purchases, push notifications, Google Play services, Nakama, and PlayFab. The Asset Portal offers reusable components and extensions. Live Update can provide additional game content after the initial download, with customizable content verification. Source code for the engine, editor, and build tools is available on GitHub under a developer-friendly license derived from Apache 2.0. Defold costs nothing, with no licensing fees, royalties, or runtime fees. Community help is available through a forum, and technical support contracts are available if needed.
