Our review
Pros	Layered maps combine tiles, images, objects, and groups. Terrain rules, autotiling, and weighted terrain fill support map building. Exports support Godot, Unity, Tiled, GameMaker, and other tools.	Free, open-source editor for Windows, macOS, and Linux Combines brushes, curve patches, terrain, entities, and shaders Includes the Q3Map2 map compiler and gamepack support
Cons	Web-only access may not suit desktop-first workflows. The editor focuses on 2D maps rather than 3D level design. AI-generated assets may require additional editing for production use.	Its focus is limited to games powered by id Tech engines Some games require separately installed gamepacks Community volunteer maintenance may mean a less centralized workflow
