Random Dungeon Room and Encounter Generator

A free random dungeon generator for tabletop games. Set party level, party size and room count and get keyed rooms with a feature, one to four exits, an optional hazard with a suggested difficulty, occupants scaled to party size and a monster tier by level, and a treasure hint as a rough gold range. Seeds make results repeatable, single rooms can be rerolled, and the whole dungeon copies as text. Original, system-neutral tables.

Everything runs offline in your browser from one HTML file. No account, no tracking, no ads, nothing is uploaded. It includes a plain-language explanation and an FAQ below the tool.
