Best Self Hosted Alternatives to Foundry Virtual Tabletop

PlanarAlly is a web-based virtual tabletop (VTT) designed for running tabletop RPG sessions with shared battlemaps and real-time player interaction. It focuses on map-based play with features to enhance immersion and enable both online and fully offline game setups.

Key Features

• Infinite canvas for large or sprawling maps and scene layout
• Layered scenes for organizing map elements (tiles, tokens, notes)
• Dynamic lighting and player-limited vision to simulate line-of-sight and darkness
• Token support and simple initiative tracker for encounter management
• Multi-floor support to view stacked levels (balconies, lower floors)
• Offline-capable and self-hostable architecture for LAN or air-gapped play
• Image/map uploads and basic asset management for custom battlemaps

Use Cases

• Running remote or local TTRPG sessions with shared maps and token movement
• Preparing and presenting encounters using layered scenes and initiative tracking
• Playing in low- or no-internet environments (conventions, home LAN, offline sessions)

Limitations and Considerations

• No built-in voice or video chat; external communication tools are required for audio/video
• Compared to larger commercial VTTs, the ecosystem of paid modules and ready-made asset marketplaces is smaller

PlanarAlly is a practical, privacy-respecting choice for groups who prefer self-hosting and want advanced map features like dynamic lighting and player vision without relying on external services. It is suitable for both casual groups and hobbyist GMs who value offline capability and extensibility.
