Comparison with Alternatives
VaultLink is one of several solutions for synchronising Obsidian vaults. This page compares VaultLink with popular alternatives to help you choose the right tool.
Key Differentiator: Editor Agnostic
VaultLink is not tied to Obsidian. While it includes an Obsidian plugin for convenience, VaultLink synchronises plain text files and works with any editor:
- Edit with Obsidian desktop on your laptop
- Edit with Vim on your server
- Edit with VS Code on your workstation
- Edit with Obsidian mobile on your phone
- Use the CLI client for automated workflows
All changes merge automatically without conflict markers, regardless of which editor you use. This is possible because VaultLink uses reconcile-text for differential synchronisation rather than requiring operation-level tracking.
VaultLink's Core Strengths
Before diving into comparisons:
- Fully self-hosted: Server and all components are open source
- Collaborative editing: Real-time sync with operational transformation
- Automatic conflict resolution: No manual intervention or paid features required
- Cursor tracking: See where other users are editing
- Extensively tested: Comprehensive test suite for server and client
- Editor freedom: Use any text editor, not just Obsidian
- Production-ready: Docker images, health checks, monitoring
Obsidian Sync Alternatives
Self-hosted LiveSync
Downloads: ~300,000 Repository: https://github.com/vrtmrz/obsidian-livesync

Remotely Save
Downloads: ~1.1M Repository: https://github.com/remotely-save/remotely-save
Overview: Sync to cloud storage providers (S3, Dropbox, OneDrive, WebDAV).
| Aspect | Remotely Save | VaultLink |
|---|---|---|
| Self-hosted | Partial (uses cloud storage) | Fully self-hosted |
| Conflict resolution | Paid Pro feature | Free and automatic |
| Collaborative editing | No | Yes |
| Editor support | Obsidian only | Any text editor |
| Storage backend | Cloud providers | Self-hosted SQLite |
| Cost | Free (basic) / Paid (Pro) | Free (open source) |
| Code quality | No tests, complex codebase | Comprehensive test suite |
| Real-time sync | No (periodic polling) | Yes (WebSocket) |
When to use Remotely Save:
- Already use cloud storage (S3, Dropbox)
- Don't need real-time sync
- Single-user scenario
When to use VaultLink:
- Want full control over data
- Need automatic conflict resolution without paying
- Want real-time collaborative editing
- Value code quality and testing
Note: Remotely Save's conflict resolution is a paid feature. VaultLink provides superior automatic merging for free.
Relay
Downloads: ~24,000 Repository: https://github.com/No-Instructions/Relay
Overview: CRDT-based sync with proprietary server component.
| Aspect | Relay | VaultLink |
|---|---|---|
| Self-hosted | No (proprietary server) | Yes (fully open source) |
| Conflict resolution | CRDT (automatic) | OT (automatic) |
| Collaborative editing | Yes | Yes |
| Editor support | Obsidian only | Any text editor |
| Out-of-band edits | No (breaks CRDT consistency) | Yes (differential sync) |
| Server open source | No | Yes |
| Infrastructure control | Limited | Full |
| Per-file overhead | High (CRDT metadata) | Low (version history) |
When to use Relay:
- Want hosted solution (don't self-host)
- Only edit within Obsidian
- Don't need out-of-band editing
When to use VaultLink:
- Need fully open source solution
- Want to self-host completely
- Edit files outside Obsidian (Vim, VS Code)
- Value infrastructure control
Critical limitation: Relay's CRDT approach requires tracking every operation within Obsidian. Editing files outside Obsidian breaks the CRDT state. VaultLink's differential sync works regardless of how files are edited.
Obsidian Git
Downloads: ~1.4M Repository: https://github.com/denolehov/obsidian-git
Overview: Uses Git for version control and synchronisation.
| Aspect | Obsidian Git | VaultLink |
|---|---|---|
| Self-hosted | Yes (Git server) | Yes (sync server) |
| Conflict resolution | Manual (conflict markers) | Automatic (no markers) |
| Collaborative editing | No | Yes (real-time) |
| Editor support | Any (it's Git) | Any (differential sync) |
| Version history | Full Git history | Document versions |
| Real-time sync | No (commit-based) | Yes (instant) |
| Merge conflicts | Manual resolution | Automatic |
| Learning curve | High (Git knowledge required) | Low |
| Workflow interruption | Yes (resolve conflicts) | No |
When to use Obsidian Git:
- Need full version control (branches, tags, etc.)
- Already familiar with Git workflows
- Want integration with existing Git repos
- Don't mind manual conflict resolution
When to use VaultLink:
- Want automatic conflict-free merging
- Need real-time collaborative editing
- Don't want workflow interruptions from merge conflicts
- Prefer simpler mental model (sync, not commits)
Key difference: Git requires manual conflict resolution with <<<<<<< markers. VaultLink automatically merges all changes using operational transformation, never interrupting your workflow.
Syncthing Integration
Downloads: ~22,600 Repository: https://github.com/LBF38/obsidian-syncthing-integration
Overview: Wrapper around Syncthing for file synchronisation.
| Aspect | Syncthing Integration | VaultLink |
|---|---|---|
