About MarkSync

Marksync syncs your bookmarks across browsers, with end-to-end encryption: your data stays readable only to you, never to the server. Key features: - Automatic bookmark sync across Chrome, Firefox, and other Chromium-based browsers - End-to-end encryption: your key never leaves your device - No account required, no tracking - Open source, GPL-3.0 licensed Marksync is an independent fork of xBrowserSync, rewritten from scratch in TypeScript and built natively for Manifest V3, for long-term compatibility with modern browsers. The project continues development after the original stalled, keeping the same core principle: your bookmark library is yours, encrypted, and no one else can read it.
