D&D Dungeon Map Generator

Generate a dungeon floor plan in a second: rooms linked by corridors, always fully traversable, with an entrance and a boss lair. Dial in the number of rooms, density, theme (cave, masonry, tomb, dungeon) and branching from a linear crawl to a full maze. Every dungeon has a seed: the same seed always rebuilds the same map, so you can return to a layout you like or share it. You get a live preview and a readable room list, exactly what you read at the table. Free, no login.

Key features

FAQ

Are the rooms always connected?
Yes, the generator guarantees every room is reachable from every other (via corridors, and via secret doors for hidden rooms).
What does the seed do?
The seed drives the randomness. The same seed with the same settings always produces the exact same map, shareable and reproducible.
Does it add monsters and treasure?
Yes. Rooms get enemies balanced by the encounter calculator, treasure rolled on the loot tables, traps with DCs, plus doors and locks. Every layer can be toggled on or off without changing the map, and a room's fight goes to the initiative tracker in one click.
