From Blank Page to Battle-Ready
Imagine that your players just wrapped up their Thursday-session tavern brawl 45 minutes early, thanks to uncharacteristically lucky rolls. Erki, the rogue, casually announces to the rest of the party that she’s going to go “explore the tunnels under the monastery next door”… and YOU PANIC.
This was not part of the plan, and you’ve got zero resources ready for an off-script delve.
Luckily, you’re covered, since you can create a fully formed dungeon in seconds, customize the elements that matter in the moment, and get back to the parts of GMing you actually enjoy… all without signing in or creating an account anywhere.
Whether you’re prepping a game the night before, playing it cool during a mid-game detour, or simply needing to get your creative juices flowing as you stare into the abyss of a blank grid… this Random Dungeon tool is the answer to your problems.
It lives in Dungeon Scrawl, right in your browser, with no install required… and every map you make can be exported, used on any VTT, broadcast to a TV or monitor for in-person play, or even printed for your kitchen table. You were born for this moment.
How It Works
Open the Random Dungeon panel from Dungeon Scrawl’s Sidebar Menu. Click Generate Dungeon to get an instant result using default randomized settings, or fine-tune them, experimenting and figuring out what looks best based on your needs. Don’t love the result? Re-generate! You can make as many random dungeons as you want, absolutely free… You don’t even need an account.
Settings
- Size sets the overall footprint of your map. Small dungeons fit perfectly inside Roll20’s 50×50 Connection window, which is handy if you’re sending it straight to a Roll20 game.
- Room Count, Room Size, Corridor Length, and Width let you scale the dungeon up or down based on how ambitious your party feels or how long you want them to spend exploring.
- Layout ranges from Straight (linear progressions) to Winding (twisty, exploratory paths), with Forking and Balanced in between.
- Door Density and Room Shapes (Square, Irregular, and Rounded) add personality and variety.
- Roughness adds an irregular texture to the walls, perfect for creating cavernous/organic edges.
Whenever you click Generate Dungeon, your new map replaces the one currently on your canvas. (A warning will confirm before this happens, since undo won’t recover a replaced map.) Make sure to save anything you want to keep first.
Pro subscribers get a safety net: once you make your first edit to a generated map, it autosaves to your library, and subsequent changes save automatically too.
Built for Every GM
GMing is a labor of love, and we know first-hand that even if you adore making maps, you don’t always have hours to spend on it. The Random Dungeon Generator was built because we were tired of:
- Unexpected detours: Your players zigged when you swore they’d zag
- Prep cram: Game night starts in three hours. You’ve got an idea, but can’t find the right map.
- The imagination kickstart: You have no ideas… or way too many. All you need is a jumpstart, then the creative juices can flow.
- That “I don’t want to draw thirty rooms” reality: Not everyone loves this part of GMing. Sometimes you’d rather skip the drudgery of setup so you can focus on intertwining storylines, coming up with puzzles, or painting your minis.
The generator’s output isn’t meant to be a finished product for everyone. If it works for you as is, that’s great, but for most GMs, it’s a launchpad. Every room, hallway, and door is fully editable in Dungeon Scrawl, so you can put your personal touches on your map to make it match your vision.
Wherever You Play
The browser-based Random Dungeon Generator is available whenever you play:
On Roll20
Use the built-in Connection to sync your dungeon directly into a campaign. No exports, no uploads, no managing files.
On Any Other VTT
Export your finished map as an image, or as a high-res or PDF if you’re a Pro subscriber. Upload it wherever your party plays.
In Person
Broadcast your map to a TV or monitor at your table with Send to Tabletop, and pair it with Lighting Mode or Fog of War to keep your players guessing at what comes next.
Wherever your party plays, your tools should be easy to find and use without friction.
“Wait… is this AI?”
Nope. The Random Dungeon Generator features procedural generation. It uses algorithms and rule-based logic to lay out dungeon layouts; there’s no training data, no model, and no scraping. It’s the same approach that popular tools like Watabou and Donjon have used for years.
Try the Beta / Share Your Feedback
This feature is in beta, which means we’re going to keep working on it based on how you use it and how you’d like to see it improve. There’s a feedback form linked in the generator’s in-app description, or you can click below… tell us what works, what doesn’t, and what you wish it did differently. Your input will influence where this goes next.
In the meantime: go make some dungeons! Stress-test it, and share what you make. We can’t wait to see what you come up with! As always, you can find our team and share your maps on Discord or Reddit. Happy scrawling!
