Make gridded floor-plan maps for tabletop RPGs. From haunted mansions to dungeon crawls.
This link holds the map as it is now. If you change the map later, press “Share this map” again to make a new link.
Anyone who opens the link sees the same map. If they change it, your map stays the same. The data lives inside the link and is not stored anywhere.
Pick one to generate a map of that type. It replaces the current map (you can bring it back with “Undo”).
