3D Dungeon Generator vs Frigga for Unity

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.
