# Foundry VTT — Virtual Tabletop for TTRPGs **Foundry Virtual Tabletop (VTT)** is a subscription-free virtual tabletop for playing tabletop role-playing games like Dungeons & Dragons, Pathfinder, and more. It provides maps, tokens, dice rolling, and real-time collaboration. ## Access - **Web UI:** - **Internal (home network):** ## Features - Interactive maps with fog of war and dynamic lighting - Token movement and combat tracking - Dice rolling with chat integration - Module and system support for multiple TTRPG rulesets - Real-time collaboration — multiple players join the same session ## Getting Started 1. Open in your browser. 2. Click **Sign In** and choose **Sign in with The Nest**. 3. If this is your first time, you'll be prompted to create a world or join an existing one. 4. Share the session link with your players. ## How It Works Foundry VTT runs as a single-instance server in The Nest. All players connect via WebSocket to the same game world. No separate client software is required — everything runs in the browser. ## Tips - **Worlds:** Each "world" is a separate campaign. Create one per group or setting. - **Modules:** Install modules for additional rulesets, maps, and tools. Admin-managed module library may be available. - **Performance:** Foundry VTT is CPU-intensive. If you experience lag, try reducing map detail or closing other browser tabs. - **Mobile players:** Players can join from phones or tablets via the web UI — no app required. ## Related Services - [Keycloak](../technical/security-and-identity.md) — Handles authentication for Foundry VTT --- *TODO: Add screenshot of a Foundry VTT combat map with tokens.*
