Official screenshots
A community- and foundation-led engine with a scene system, editor, scripting, rendering, physics, and export tools.
Why use it
No royalties, reviewable source, and version-control-friendly projects give indie teams durable control of the stack.
Where it fits
Find engines, frameworks, code libraries, version control, and production automation.
What to check
Console releases generally need approved third-party ports or services, and ambitious 3D projects should validate performance early.
