Your tiles,
endless dungeons.
Drop in your own tiles, pick a size and let Dungeon Forge weave a fresh, connected dungeon every time — yours to save, export and share.
The macOS build is unsigned — on first launch, right-click the app and choose Open.
Pick a size. Generate a dungeon.
Dungeon Forge stitches your tiles into a connected map — corridors, corners and rooms laid out fresh on every roll, with a seed you can keep.
A dungeon generator built around your own art.
Your own tile-sets
Upload and manage your tiles — Dungeon Forge builds every map from your art, not a fixed library.
Sorted by type
Group tiles into corridors, corners, junctions, rooms and entrances/exits so they snap together cleanly.
Shape every map
Dial in size, complexity, dead-end and room density, and the overall layout shape until it feels right.
Seed-based generation
Every dungeon comes from a seed like #A7F3 — reproducible and shareable to the tile.
Save & export
Keep maps in the app and export any of them to PNG for your VTT or the printer.
Bilingual & offline
A bilingual interface that runs fully offline — no account, no connection, no tracking.
Three steps to a finished map.
Load your tiles
Upload your tile-set and sort the pieces into corridors, corners, rooms and entrances/exits.
Set the dials
Pick a size and tune complexity, density and layout shape — or just trust the defaults.
Generate & keep
Roll a dungeon, save the ones you like and export to PNG; the seed makes it shareable.
