Cauldron VTT

What Cauldron VTT is

Cauldron VTT is an online tabletop for groups playing role-playing games, available on the web and as an extension. Its generic dice system is intended to support any ruleset that uses dice, and its current supported systems include Cyberpunk Red, Daggerheart, Dungeons & Dragons 5e, Pathfinder 2e, and Star Wars 5e. Dungeon Masters can create maps with fog of war and use either still images or video. The creator describes it as a lightweight tabletop for groups that want to move between online and in-person sessions; it is not intended to replace character sheets or provide spell and magic item lists.

The Cauldron20 browser extension can read D&D Beyond character sheets and implement those characters in Cauldron VTT. The extension's resources page lists Chrome, Opera/GX, Microsoft Edge, and Firefox. Players need an invitation code from their DM or GM to connect to that group's adventures. Cauldron is open source, with source code linked on GitLab, and creator and maintainer Hugo Leisink directs people with questions to the Cauldron Discord server. The free plan includes campaign tools and a rules compendium. Resource storage is capped at 100 MB per account, and uploads larger than 20 MB are blocked.

Who it suits

Cauldron VTT suits role-playing groups looking for a lightweight online tabletop with a generic dice system and map tools. It is also a fit for groups that want to switch between online and in-person sessions, provided players can get an invitation code from their DM or GM.

Limits

The free plan includes 100 MB of account resource storage, and files over 20 MB cannot be uploaded.

Getting started

1. Open the Cauldron VTT website.
2. Use the web version or extension.
3. Ask your DM or GM for an invitation code to connect to the group's adventures.
4. If using Cauldron20, use a browser listed by its resources page: Chrome, Opera/GX, Microsoft Edge, or Firefox.

Verdict

Choose Cauldron VTT if your group wants a free, lightweight tabletop with dice support, map creation, and campaign tools. Look elsewhere if you need the tabletop itself to provide character sheets or spell and magic item lists.
