How Relay works

• Real-time multiplayer vs repurposed file sync How Relay's CRDT-based approach differs from file sync tools repurposed for collaboration.
• How Relay connects your devices How Relay connects local Obsidian vaults through a server, stores shared content, and coordinates access through the Control Plane.
• What Relay can see An explanation of the data that reaches Relay's servers under self-hosted vs Relay-hosted setups.
• Storage for shared files How Relay stores shared files, which files count toward storage on a Relay-hosted server, and how to get storage by self-hosting or with a paid plan.
• How Canvas collaboration works How Relay merges changes to Canvas cards, text, and connections while keeping a .canvas file in your Obsidian vault.
