Getting started

Which setup fits your table, and the fastest path to a first session on each of them.

  1. Which setup fits your tableOpen Dungeon Master runs three ways: a world hosted on your own phone or computer, a friend's world you join, or a server somebody runs for the group. What each one gives you and what it costs.

  2. System requirementsWhat each setup needs, in one place: the app on a computer or a phone, who tells the story (a person, an API key, an agent program or a local model, with the 16 GB minimum, gpt-oss-20b for a 16 GB gaming card and the machines it was measured on), local pictures, and hosting a group.
