Dungeon map generator

Roll a dungeon and get a real floor plan at 5 feet to a square: rooms of every shape cut from the rock, passages that turn at 45° as well as square, doors and secret doors, and stairs down to the next level. Each room has a purpose and is furnished to match, and the key to every one is written from what's really there.

What it makes

Rooms with a purpose

Pillared halls, shrines with an altar, crypts lined with urns, libraries, barracks, armouries, kitchens, a throne room on its dais and a treasure room or two, each furnished to match.

Not all right angles

Round, octagonal, cross-shaped and tilted rooms, alcoved halls and rough natural chambers, joined by passages that run at 45° as often as square. Every map is connected end to end.

A key you can read out

Each numbered room gets an entry written from what's really in it: its purpose, size in feet, contents, doors and the walls its secret doors hide in. Copy the whole key as text.

Deeper levels

Generate two or three levels stacked up, each one's stairs down landing on the next one's stairs up, or add and rearrange levels yourself.

What you can set

Size
32 × 24 up to 96 × 72 squares, or a custom size
Setting
Stone dungeon, frozen, infernal or sewer
Levels
One to three generated; add more by hand
Encounters
Goblins, skeletons and worse as tokens, or none
Exports
PNG, and Universal VTT with walls, doors and lights

Questions

Is it free?

Yes, while we're in early access. You can make, edit and export maps with no account. Sign in when you want to keep them and link them together.

Which games does it work with?

It isn't tied to any rules. Game maps are 5 feet to a square, so they suit any tabletop RPG played on squares. There's no hex grid on game maps yet.

Can I change the dungeon after it's generated?

All of it. It opens in a full editor: move walls and doors, draw new rooms, repaint floors, place furniture and lights, and add tokens. It's a map made of real parts, not a flat picture.

Can I hide it from my players and reveal it as they explore?

Yes. Every map has fog you paint away room by room. Run it at the table from a campaign, and players see only what you've revealed, with secret doors drawn as wall.

How are the maps made?

By rules, not by drawing a picture: the generator lays out the map from a seed, so the same seed gives the same map. Some of the art it draws with is made with image models.
