# LoomVTT

> LoomVTT is a modular tabletop RPG platform designed for playing, creating and distributing digital tabletop roleplaying experiences.
LoomVTT combines a modern Virtual Tabletop engine with an extensible platform for Game Masters, Players, Developers and Publishers.
Game Masters can build immersive campaigns using tactical maps, journals, actors, items, compendiums, dynamic lighting, multiplayer synchronization and automation.
Players join games instantly through the browser with a responsive tabletop experience and no complex setup.
Developers can build complete Rulesets, Addons, character sheets, automation, integrations and custom tools using the official SDK, Hooks and public APIs.
Publishers can distribute official game systems, adventures, compendiums and premium digital content through Loom Hub using integrated licensing and API Key management.
LoomVTT follows an engine-first architecture where Rulesets remain independent from the core platform, allowing new tabletop RPG systems to be created without modifying the engine, allowing community-created projects and commercial publisher content to coexist.
Its mission is to provide an open platform where tabletop RPG experiences can be played, created, published and distributed.
