Defold
A complete engine governed by the Defold Foundation, including editor, Lua runtime, build service, and extension system.
Why use it
A small runtime and centralized build pipeline suit 2D teams prioritizing iteration speed and multiplatform delivery.
Where it fits
Find engines, frameworks, code libraries, version control, and production automation.
What to check
The Defold License permits free commercial games but is not OSI-approved, and 3D tooling is shallower than larger engines.
