MySync

Sync tabs across Chrome and Firefox browsers with self-hosted server

MySync is a lightweight, privacy-first browser extension that syncs your open tabs, bookmarks, and browsing history across all your devices and browsers in real-time. Built to be completely self-hosted, it ensures that your browsing data never touches third-party servers. You are in full control of your data from end to end. **Key Features:** * 🔄 **Real-Time Cross-Browser Sync:** Whether you use Chrome on your desktop, Firefox on your laptop, or a mix of both, MySync keeps your active tabs, bookmarks, and browsing history perfectly mirrored in real-time. * 🛡️ **100% Self-Hosted & Private:** No proprietary clouds, no tracking, and no subscriptions. Run the open-source lightweight Go backend on your own hardware or VPS, ensuring nobody has access to your browsing history except you. * ⚡ **Lightning Fast Conflict Resolution Powered by WebSockets/SSE:** With polling fallbacks, MySync uses optimistic locking and last-write-wins conflict resolution. It handles sudden network drops or rapid tab changes without breaking a sweat. * 🔑 **Simple, Passwordless Pairing:** No need to manage complex accounts or passwords. Connect a new browser instantly using a 6-character device pairing code, a CLI-generated invite token, or a secure magic link. * 💻 **Built-in Device Management:** Easily manage all your connected browsers directly from the extension's options page. Rename devices to easily identify them or instantly revoke access to an old laptop or phone. **How it works:** 1. Host the lightweight MySync Go server (recommended) or you can use backend hosted on our server (https://mysync.absons.net). 2. Install the MySync extension on your browsers. 3. Generate a one-time invite token from your server to pair your first device or use pair by email to get a magic link. 4. Add your other devices seamlessly using simple 6-digit pairing codes! *(Note: MySync requires the companion self-hosted server to function. You can find the full setup instructions and open-source server code at the project's repository: https://github.com/absonsnet/mysync)*
