A first look at Obsidian Shared Vaults (v0.14.10 insiders beta)

Obsidian’s new multiplayer synchronization in insiders beta turns personal sync into a shared vault: an owner creates a password-protected vault, invites collaborators by email, and each participant must hold an Obsidian Sync subscription. The vault counts only against the owner’s quota, while each subscriber has a separate quota allowance (described as 5 vaults to synchronize). Beyond that billing model, the core mechanics mirror personal sync—selectable synchronization of folders, plugin settings, plugin code, and a synchronization history—so teams get a familiar workflow with the added ability to collaborate inside one shared workspace.

Setup is straightforward. The owner enables sync for a new vault, sets a password, and sends an invite link to a collaborator’s email. The collaborator accepts the invitation in their Obsidian account, then enables the shared vault under synchronization settings. In practice, both sides also need to enable the same categories of synchronization (plugins, plugin settings, and data) and turn on community plugins so the shared environment matches. In the tested scenario, the entire process took only a few minutes.

Where the experience becomes uneven is real-time parallel editing. When both collaborators edited the same Markdown document, Obsidian produced edit conflicts that were not always clear—especially around whether changes were overwritten. The tester reported seeing tag entries overwritten by the other person’s text, suggesting that simultaneous edits to the same document regions can still collide in ways that are hard to diagnose.

The synchronization history also proved difficult to use for team troubleshooting. For personal use, it’s described as helpful, but for collaborative work it lacked the granularity needed to reconstruct what happened during conflicts. Warnings were inconsistent, and even when warnings appeared, the history did not make it easy to untangle the sequence of conflicting updates.

Permissions management introduced another surprise. Removing a collaborator’s permissions was easy, but the collaborator’s vault continued synchronizing changes until the collaborator restarted Obsidian. In other words, access revocation did not immediately stop incoming updates, creating a window where “kicked out” users could still affect the shared vault.

The practical recommendation is to treat Obsidian multiplayer sync as early-stage collaboration rather than a full real-time system. The tester found it laggy compared with a true shared whiteboard experience, and conflict handling makes larger teams risky. For groups larger than a couple of people, the probability of collisions rises and the current history and conflict tooling are not robust enough to handle frequent edge cases. For bigger teams, the tester suggests using a more transparent version-control workflow such as GitHub sync, with check-in/check-out behavior and clearer attribution of changes.

Still, the workflow can work well when collaboration is structured to avoid collisions. Editing “atomic” documents—small, separate files—reduced conflicts dramatically, with a main document using transclusion to assemble the final view. With Obsidian’s rapid development pace, the tester expects improvements in synchronization and conflict resolution in the near term, but for now positions multiplayer sync as best for small groups and carefully partitioned writing rather than large, simultaneous collaboration on shared documents.
