About DungeonGen

DungeonGen is a free, no-sign-up random dungeon generator built for tabletop RPG players and dungeon masters — D&D 5e, solo play, and anything in between. One click gives you a named dungeon, a printable grid map, and a room-by-room list of monsters, traps, and treasure.

What it's for

Session prep that runs long. A solo game with no DM. A blank map and no inspiration. The generator is a first draft you can keep, edit, or throw away — everything it produces is yours to use in home games and published adventures.

How it works

A seeded random number generator builds the layout and contents. The same seed always reproduces the same dungeon, so you can save a layout or share it with another DM. No account, no tracking beyond standard analytics.
