Your game happens around a table. Your app should too.
The easy way to run and play tabletop RPGs at the table.
Campaign Hall is a web app for running tabletop roleplaying games in person. The GM runs the session from a phone, tablet, or laptop, and players follow along on their own phones. No downloads, nothing to install.
Closed beta for game masters

- Your dice, first.Roll your real dice and type the number in. "Roll for me" is there if someone forgot their bag.
- Fights that keep moving.Everyone's phone shows whose turn it is, what they can do, and what just happened.
- Several game systems.With a guided character builder for each one.
- Meet the Bard, your guide at the table.He welcomes new players and shows them around.
- AI helpers for GMs (adults 18+).Prep suggestions and session recaps. AI never rolls your dice, never decides the rules, and never runs in kids' seats.
Art shown is AI-generated concept art. It's a placeholder, and human artists will redo it.
Free for players, always. Campaign Hall opens in the US first, with other countries to follow. It's coming to Kickstarter in early 2027, to pay for what a small app needs before it opens to everyone, including human artists and a Family Safety Review of kids' seats.
