About this extension
Keep your bookmarks and tabs synchronized across different browsers and devices without depending on a vendor-specific cloud service. SyncMarks synchronizes bookmarks and open tabs across browsers using your own self-hosted server.

Unlike browser vendor cloud synchronization, SyncMarks gives you full control over where your data is stored. No vendor specific account or other third-party cloud service is required.

Use SyncMarks to keep your bookmarks synchronized between Firefox, Microsoft Edge, Chrome and other supported browsers. Each browser profile can have its own independent configuration and connect to a different SyncMarks server.

Features
• Synchronize bookmarks across browsers
• Synchronize open tabs between devices
• Self-hosted server architecture
• No vendor lock-in
• No third-party cloud required
• Independent configuration for each browser profile
• Cross-browser synchronization
• Open Source
• Privacy-focused

How it works
SyncMarks consists of a browser extension and the SyncMarks WebApp.

The extension connects to your SyncMarks server and synchronizes your bookmarks and tabs. You decide where your data is stored and how your server is operated.

The SyncMarks WebApp can be deployed on your own infrastructure. Installation instructions and source code are available in the project documentation.
