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.

What it does

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.

How it works

Three steps to a finished map.

01

Load your tiles

Upload your tile-set and sort the pieces into corridors, corners, rooms and entrances/exits.

02

Set the dials

Pick a size and tune complexity, density and layout shape — or just trust the defaults.

03

Generate & keep

Roll a dungeon, save the ones you like and export to PNG; the seed makes it shareable.
