felt

felt is a virtual tabletop webapp written in Go with a vanilla Javascript frontend and using MongoDB for data storage.

felt is game-system agnostic, being suitable for various types of TTRPGs, like D&D, World of Darkness, GURPS, etc. Gamemasters can register an admin account, upload maps, craft tokens, and use felt to facilitate puzzle scenes, battle scenes, exploration/investigation scenes, and more. In addition to the token system, it features a built-in dice roller and log as well as a shared status display. The websocket connection enables instant updates between clients and the frontend is extremely lightweight (~210KB), themeable, and responsive.
