A dungeon generator for connected, editable maps. Choose rooms and floors, adjust the passages, and add optional artwork when the structure fits your adventure.
Use a spatial plan to decide where the party can go.
Choose four to sixteen rooms and up to three floors. The dungeon map maker connects the passages and keeps your previous project separately.
Move a doorway, rename a chamber, or draw another route. Switch floors in the dungeon generator without replacing the changes on another level.
Choose the grid and distance scale in the dungeon generator. Export the current floor, and download an editable project backup for the complete location.
Start with a route through the location. The dungeon generator connects rooms so you can inspect chokepoints, place a guarded entrance, and adjust the approach to your final chamber before adding encounter details.

Choose branching passages for direct exploration or loops for alternative approaches. Rooms, corridors, walls and doors remain editable, letting you adapt a first arrangement into a crypt, prison or stronghold with your own decisions.

Prepare the entrance level and lower vault separately. Each floor retains its own layers and selected artwork, so moving a door or changing an illustration on one level preserves the work on the others.

Once the dungeon map generator has connected your rooms, switch to Design for optional artwork. Compare the illustration against your editable geometry and keep that structure for precise distances and route planning.
Try this layoutSpend preparation time on the decisions your players will notice. Keep a clear route, preserve useful work, and choose the amount of visual detail your next session needs.
Let the dungeon generator handle initial room connections while you decide where the party enters and which chamber matters most.
Build another layout as a separate project. Keep the earlier arrangement available while comparing routes for a later session.
Use the dungeon generator layout for measurements and annotations, then add artwork when atmosphere helps you present the location.
Download an editable backup before changing devices or clearing website data. Keep an independent copy of your prepared location.
Layouts, layer editing, saving and file exports are free. Optional AI generation or editing uses one credit per action. Verified accounts can try one generation and one edit on the same project, once in total.
Change the seed in Advanced layout settings. The same seed and settings reproduce the same geometry, and building a new arrangement preserves the previous project.
The DnD dungeon map generator supports four to sixteen rooms per floor and up to three floors. Choose room spacing, corridor width and optional doors, then edit the resulting layers.
Branching connects rooms through a tree of passages; looped adds alternative connections. Inspect the dungeon generator preview, then draw or reposition layers where another approach would help the adventure.
Use the dungeon generator to prepare map geometry and labels. Add monster statistics, treasure and encounter decisions through your own game notes; those choices remain separate from the floor plan.
Build a layout in the DnD dungeon map maker, select a layer, and edit its label or position. Use drawing tools to add doors, walls, floors or stairs.
AI artwork can alter room shapes. Keep the dungeon generator layout for exact connections and distances, and compare the illustration with that geometry before choosing the map for play.
Sign in to save dungeon generator projects and up to twelve image versions privately to your account. Guest drafts stay in this browser; download a backup for an independent copy.
Sign in to the same account and open your saved dungeon generator project. For a guest draft, transfer an exported backup and import it through Project & imports.
Export Universal VTT data from the dungeon generator for the current floor. It includes manual walls and doors; check scale and import behavior in your intended host.
Use it as a dungeon crawl map maker: connect rooms, label objectives and keep distinct floors. Structural editing and PNG exports work without an AI call, and backups preserve the editable location.
This is an independent dungeon generator with its own editable workflow. It has no affiliation with donjon or promised donjon-file import; use your preferred rules resources for encounter tables.
Start with connected rooms in the dungeon generator, then shape doors, passages and floors around your adventure.
