DungeonRevealer

Updated 21 October 2026

Dungeon Revealer does one thing extremely well: it puts a battle map on your players' screens with a fog of war you control, and you wipe the fog away as they explore. The DM sees the whole map. The players see only what you've revealed.

That is the entire pitch, and it's why people keep using it alongside heavier virtual tabletops. There is no game system to install, no character sheets, no module ecosystem to maintain. Upload an image, draw the grid, and start playing. It also does tokens, a shared dice roller, notes, and a chat sidebar, but the map is the point.

Hosting it here means the map is at a fixed HTTPS address your table can bookmark, and your uploaded maps live on backed-up storage.

How do I access DungeonRevealer?

DungeonRevealer is available:

• From your dashboard: https://your-username.elfhosted.com
• Directly: https://your-username-dungeonrevealer.elfhosted.com

How do I use it?

Set your passwords first

Dungeon Revealer has two roles, each behind its own password:

• DM, who sees the whole map, reveals areas, and moves tokens
• Player, who sees only revealed areas

These are set with the DM_PASSWORD and PC_PASSWORD settings, which you can change using ElfBot. Set both before you share the address with anyone.

Your instance is deliberately not behind ElfHosted's SSO, because your players aren't ElfHosted customers and can't sign in to it. Dungeon Revealer's own passwords are the only thing standing between the internet and your maps, so give them the same care you'd give any other password.

Running a session

Sign in as DM, upload a map image, and set the grid so token sizes make sense. The map starts fully fogged; use the brush and area tools to reveal as your party moves. Push a map live to the player view when you're ready, and keep the next one staged and hidden until they get there.

Send your players the same address. They pick Player, enter the player password, and see the live map.

Maps

Any image works. Bring your own, or grab maps from the many free and paid mapmakers around. Large, high-resolution images are fine, though very large files take longer to reach players on slow connections.

What it deliberately doesn't do

No character sheets, no automated rules, no combat tracker. If you want those, Foundry VTT is the heavier tool, and plenty of tables run both: Foundry for the campaign, Dungeon Revealer for a quick one-shot where setup time matters more than features.
