Dungeon Scrawl
app.dungeonscrawl.com
Browser-based tabletop RPG map maker for drawing dungeons, towns, and battlemaps quickly, with exports for print and virtual tabletops.
Why it is useful
Dungeon Scrawl is tuned for speed, which is exactly what game masters need when a session goes off-script. Instead of forcing design-software habits onto RPG mapmaking, it gives you an interface built for sketching rooms, corridors, and playable layouts fast. That balance of accessibility and control is why it keeps showing up in actual prep workflows.
