Welcome to the Cauldron VTT community. Cauldron VTT is a free and open source virtual tabletop, which can be used to play roleplaying games online. It’s a bit like Roll20, but with a faster and more user friendly interface. It has special features for Dungeons & Dragons 5e and pathfinder, but with its generic dice rolling options, you can use it for any RPG rule system you like. It has three types of fog of war, dynamic lighting, in-game 3D dice, an easy-to-use combat-tracker, scripting to make things easier for the dungeon master, support for image and video battle maps but also quick and dirty line drawing on an empty grid and much more. All for free, no dirty catch, programming is a hobby and it’s my gift back to the RPG community.
Cauldron VTT also has a map market, containing several free maps that have everything needed for fog of war and ready to be imported in your adventure with a single click. The adventure market contains several free one-shot adventures, but also the Lost Mine of Phandelver and the Curse of Strahd!
