3D Dungeon Generator vs WorldEngine

3D Dungeon Generator makes procedural, solvable room-and-corridor dungeons in a browser. It places rooms without overlap and connects them with carved corridors; users can adjust room count, room size, and corridor width. A seed and its settings can reproduce the same layout, including a route from entrance to exit, with optional extra corridor links. The real-time preview supports orbiting, a top view, fit controls, and first-person walking from the entrance. Themes include Stone, Backrooms, Dungeon, Concrete, Sci-Fi, and Hedge, and users can supply wall, floor, and ceiling textures. GLB export includes the dungeon geometry and current materials, with options for a ceiling and solution path. Custom texture support in exported GLB depends on browser image decoding. The tool is free at free, browser-based, and requires no signup or subscription. Dungeon sizes range from 16×16 presets to custom dimensions up to 60×60. LevelRift Labs lists uses such as game level prototyping, game jams, dungeon concepts, and Blender or other GLB-compatible workflows. The product page says original texture files are not uploaded by the app.

WorldEngine is free, MIT-licensed software for procedural world generation. It models processes such as plate simulation, rain shadows, erosion, humidity, and terrain permeability to generate world data and images. Outputs include elevation, precipitation, temperature, biome, and ocean maps, as well as heightmaps and biome maps. Users can set a seed, and the command line can create an ancient-looking map from a world file. Worlds can be saved in protobuf or HDF5 formats; HDF5 support requires the optional h5py dependency. Python applications can load world files using WorldEngine as a library, while Java applications can use WorldEngine-Java. Installation instructions cover Docker, source, and uv, but the package is not currently released on PyPI. WorldEngine requires Python 3.9 or later and supports versions through 3.14. A separate graphical interface is available as an experimental, limited project. The project invites questions, suggestions, and contributions through its Google group or by opening an issue.
