How is Relay different?

Relay differs from other popular Obsidian collaboration tools like Obsidian Sync in that it uses a purpose-built, open-source collaboration system called a CRDT to support true real-time multiplayer. It’s not just multiparty file sync. With Relay you can:
  • Share specific folders from your vault while keeping the rest private
  • Sync keystrokes instantly and see collaborators’ cursors as they type
  • Work offline and smoothly converge when you come back on
Relay lets you keep what’s great about Obsidian — markdown files in a local-first architecture — and add modern team collaboration.

​
Is Relay free?

Relay has a free tier and paid tiers. We believe, with Obsidian, that quality software deserves your hard-earned cash. By paying for Relay you’re funding our small team to continue developing and maintaining what we endorse as a high-quality service. We do not sell your data and we do not look at it. See our privacy policy. We do not sell advertising. We are self-funded. Our revenue comes entirely from subscriptions from our customers. The paid tiers enable us to maintain a free tier, which makes the service accessible to students, hobbyists, and people just trying it out.
