What's Good
Defold License v1.0. Forever free, no royalty. Lua scripting, HTML5 and native targets. Source available to read and build games. Small runtime, editor included.
The Catch
LOUD: source-available NOT OSI Open Source — §4a may not commercialize as a Game Engine Product. Forever free for making games; license is not MIT/Apache. Vs Phaser/melonJS/KAPLAY JS engines. Distinct from Phaser, melonJS, and KAPLAY.
Verdict
Forever-free Lua engine. Source-available — not OSI OSS; do not ship it as your own engine product.
