What Cauldron VTT is
Cauldron VTT is a free online virtual tabletop for role-playing groups, available on the web and as an extension. Its generic dice system is intended for any ruleset that uses dice, while currently listed supported systems include Cyberpunk Red, Daggerheart, Dungeons & Dragons 5e, Pathfinder 2e, and Star Wars 5e. Dungeon Masters can create maps with fog of war using still images or video. The creator describes Cauldron as lightweight: it does not replace character sheets or provide spell and magic-item lists. The Cauldron20 browser extension reads D&D Beyond character sheets and implements those characters in Cauldron VTT; listed browsers include Chrome, Opera/GX, Microsoft Edge, and Firefox. Players need an invitation code from their DM or GM to join adventures. The open-source project includes campaign tools and a rules compendium. Storage is limited to 100 MB per account, and uploads over 20 MB are blocked.
