## Description

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.

<strong>Key Features:</strong>
<ul><li>🔄 <strong>Real-Time Cross-Browser Sync:</strong> 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.</li><li>🛡 <strong>100% Self-Hosted &amp; Private:</strong> 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.</li><li>⚡ <strong>Lightning Fast Conflict Resolution Powered by WebSockets/SSE:</strong> 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.</li><li>🔑 <strong>Simple, Passwordless Pairing:</strong> 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.</li><li>💻 <strong>Built-in Device Management:</strong> 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.</li></ul>
<strong>How it works:</strong>
<ol><li>Host the lightweight MySync Go server (recommended) or you can use backend hosted on our server (<a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/17e2b20b4f4003b327cd526c5711fbf6c648799c911f98843d9706c806bb4260/https%3A//mysync.absons.net" rel="nofollow">https://mysync.absons.net</a>).</li><li>Install the MySync extension on your browsers.</li><li>Generate a one-time invite token from your server to pair your first device or use pair by email to get a magic link.</li><li>Add your other devices seamlessly using simple 6-digit pairing codes!</li></ol>
