Donjon or Dungeon Flow?
Stick with Donjon if…
- You want one of Donjon's older-edition generators.
- You want Donjon's Five Room Dungeon Generator, which is purpose-built for that adventure format.
- You want deep pre-generation controls (motif, seed, corridors, layout) and plan to take the roll as-is.
- You prefer a single-page generator with no workspace or editor to learn.
Choose Dungeon Flow when…
- You play D&D 5e, Pathfinder 2e, or Shadowdark and want system-aware encounters, traps, and treasure.
- You want to tweak the flow, encounters, traps, treasure, and room details after the initial roll without regenerating everything.
- You want to move rooms, or resize, reshape, and reroute corridors on the map.
- You want to place props like altars, pillars, rubble, and furniture so rooms and corridors don't all feel the same.
- You want a flowchart view of the dungeon structure so you can see how rooms connect without getting lost in map details.
- You run Foundry VTT and want walls, doors, line of sight, and room journals imported into a linked scene.
- You play on another VTT and want Universal VTT export (.dd2vtt) with walls, doors, and line of sight on platforms which support UVTT.

Generate a free dungeonQuestions about Dungeon Flow and Donjon
Is Dungeon Flow a good Donjon alternative?
Yes, especially for D&D 5e, Pathfinder 2e, or Shadowdark GMs who want to keep refining a dungeon after generation. Dungeon Flow supports in-place content and flow edits, saved projects with shareable remix links, and Pro VTT exports with walls, doors, and line of sight. Donjon remains the stronger fit for a quick roll with deep pre-generation controls or one of its legacy-system generators.
Is Dungeon Flow free like Donjon?
Not quite. Donjon is fully free with no signup. Dungeon Flow lets you generate, make basic edits, and export 100 dpi PNGs without an account. A free account adds saves, PDFs, DM references, props, and remixing. Pro is $5/month and adds larger maps, advanced map editing, 300 dpi exports, Foundry import/export, and Universal VTT (.dd2vtt) export.
Isn't Donjon a whole suite of tools, not just a dungeon generator?
Donjon hosts many separate generators for names, weather, towns, and more. They are handy, but for dungeons, Dungeon Flow is a single integrated workspace for generating, editing, saving, sharing, and exporting the result.
How do generation speeds compare?
Both produce a dungeon in seconds. Each involves a quick setup step with different inputs before you generate.
Can I edit a Donjon dungeon without regenerating?
No. Donjon has deep pre-generation settings but no editor afterward, so any change means rolling a whole new dungeon. In Dungeon Flow, flow, content, note, and room-position edits are free; Pro adds direct room reshaping and corridor rerouting.
Does Dungeon Flow export to Foundry VTT?
Yes. An official Foundry module links to your Dungeon Flow account and exports walls, doors, line of sight, and room journals into a scene, with re-import when you update the dungeon. This is a Pro feature. Donjon relies on unofficial JSON importers.
What is the difference between Donjon's Five Room Dungeon Generator and Dungeon Flow?
Donjon's Five Room Dungeon Generator is purpose-built for the five-room adventure format, with a map and encounters shaped to that structure. Dungeon Flow can produce five-room layouts along with larger dungeons, then lets you edit, save, share, and export the result.
Which game systems does each support?
Donjon has separate generators for AD&D, d20/3.5, Pathfinder 1e, and D&D 4e, 5e, and 5.5, but not Pathfinder 2e or Shadowdark. Dungeon Flow supports D&D 5e, Pathfinder 2e, and Shadowdark with system-aware encounters, traps, and treasure.
How do the map styles compare?
Donjon's dungeon maps are functional, with several utilitarian styles locked in at generation. Dungeon Flow offers multiple map styles, including a hand-drawn aesthetic, Old School Blue, and more. You can change the style on a saved dungeon without changing the layout.
