Cauldron VTT

Welcome to Cauldron

Any rule system

Cauldron is a virtual tabletop (VTT) to play role playing games online. With its generic dice system, you can play any rule system you want, but it has some extra support for rule systems that use the d20 dice and armor class for combat, like Dungeons & Dragons and Pathfinder.

Easy to use

Cauldron's lightweight interface allows you to quickly and easily create adventures and battle maps and is easy for users to learn. Cauldron has an intuïtive interface, but also has an online manual which holds everything you need to know about Cauldron to get you started.


Cauldron is and will always be free to use. For me as the creator, it's just a hobby project and a gift back to all those who also create and freely share D&D content. I even made it open source, so you can change and extend it in any way you want.

Cauldron VTT has the Lost Mine of Phandelver and the Curse of Strahd available in its adventure market!
