Generated and furnished result

A visually furnished battlemap ready to place in a VTT.

Move rooms and corridors
Move rooms and corridors without regenerating the entire map. And without redrawing every little detail by hand.

Edit room content in place
Change descriptions, encounters, traps, treasure, and GM notes without leaving the editor.

Add props to the map
Creating a ruined sanctuary? Place props like altars, pillars, and rubble on the map. Bandit hideout? Drop in cots, tables, and more.
“Dungeon Flow is the best random dungeon generator I’ve ever used, and I’ve used a lot of them in my 25+ years playing D&D.”

Integrations
Yes, especially if you want to keep editing after generation or need encounters, traps, treasure, notes, PDFs, and saved projects. DunGen.app remains stronger for automatic furnishing and generating maps directly inside Foundry.
Not quite. Dungeon Flow lets you generate, make basic edits, and export 100 dpi PNGs without an account. A free account adds saves, PDFs, props, and remixing. Pro is $5/month. DunGen.app generates free maps at 70 px/tile; higher-resolution maps, automatic walls/lighting, and commercial use require paid tiers.
No. DunGen.app has no post-generation dungeon editor, so structural or content changes mean regenerating or editing outside the tool. In Dungeon Flow, flow, content, note, and room-position edits are free; Pro adds direct room reshaping and corridor rerouting.
DunGen.app can generate and create a map directly inside Foundry and supports older Foundry versions. Dungeon Flow lets you edit and save in its workspace, then import walls, doors, grid data, and room journals and re-import after later changes (Pro).
Dungeon Flow includes commercial use with $5/month Pro. DunGen.app’s commercial license is on the $25/month Dungeon Merchant tier.
