Problem
Obsidian Sync provides excellent end-to-end encrypted (E2EE) synchronization across devices, but lacks native sharing of individual files or folders with collaborators—whether Obsidian users or not. Users must resort to insecure third-party services like Google Drive or Dropbox, exposing E2EE data to non-zero-knowledge providers. This defeats Obsidian’s privacy promise, especially since Sync is paid ($8/month for Plus), making selective sharing a core expected feature [web:19][conversation_history:25].
Use Case
I use Obsidian Sync as my primary E2EE Drive replacement: Markdown files, attachments, and folders for projects, knowledge bases, and documents. Sharing is essential for:
- Obsidian users: Add shared folders to their vault for seamless collaboration (view/edit/merge).
- Non-users: Browser-based view or lightweight edit mode (simple Markdown tweaks without full Obsidian).
Examples: Share project briefs with clients (read-only), co-edit specs with team members, or let family view trip plans—all without compromising E2EE [web:3][conversation_history:25].
Proposed Solution
Add Sync Sharing UI in Settings > Sync:
- Select file/folder → Generate share link/ID with permissions (View, Edit, Comment).
- Obsidian users: Paste link/ID into vault → auto-syncs as remote folder (selective merge/conflict resolution).
- Non-users: Link opens private web viewer (like Publish, but E2EE) with basic Markdown editor.
- E2EE preserved: Client-side decrypt via recipient’s vault password or temp key.
- Controls: Expire links, revoke access, version history per share.
| Feature | Obsidian User | Non-User |
|---|---|---|
| Access | Vault integration | Browser viewer |
| Permissions | View/Edit/Comment | View/Edit (light) |
| E2EE | Native | Client-side decrypt |
| Limits | Sync quota | Read-only bandwidth |
Existing Workarounds (Insufficient)
- Cloud alternatives: Breaks E2EE (no sharing via OneDrive without exposing keys) [conversation_history:31].
- Plugins like “File Share”: Shares single files via links (good start!), but no folders, no collab, no E2EE integration [web:17].
- Remotely Save/Syncthing: Peer-only, rate-limited, no browser access [conversation_history:31].
These force vault duplication or insecure exports, unsuitable for paid Sync users [web:1].
Benefits
- Privacy-first collab: Retains Obsidian’s E2EE edge over Notion/OneNote.
- Monetization: Upsell via share quotas (e.g., 5 GB free, more on Plus).
- Adoption: Enables team/business use without vault proliferation.
Existing requests echo this (view-only mode, selective shares) [web:1][web:6].
Please prioritize—Sync sharing is table stakes for a modern E2EE Drive! ![]()
