3D Dungeon Generator vs Heightmap Level Generator

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.

Heightmap Level Generator creates procedural terrain and heightmaps in a browser for Unreal Engine, Unity and Godot. Its GPU-based generation uses WebGPU compute shaders and WGSL. Outputs include 16-bit heightmaps with features such as cliffs, hills, mountains, erosion, rivers, lakes and a raised border ring. It can also generate connected roads, towns, map exits, road grades and embankments around water, with temperate, steppe, desert and snow world biomes. Users can adjust settings live, compare 12 seeds, preview a 2D map and 3D mesh, and walk through terrain in first person. Exports include engine-specific terrain formats, Web or three.js formats, heightmaps, splatmaps, masks, water levels, color maps, layout JSON, glTF meshes and metadata JSON. Road, town and water masks and layout data can support PCG, Houdini and custom placement scripts. The free project supports share links, presets, JSON save and load, and undo and redo. Online use requires a WebGPU-capable browser; local use requires Node.js and such a browser.
