BrowSync от Tao Chen

BrowSync is a macOS native app that makes Safari, Chrome, FireFox work together. It unifies your browsing experience through a local WebSocket daemon, browser extensions, intelligent URL routing rules, and cross-browser data synchronization.

The BrowSync extension connects your browser with the BrowSync desktop app to locally sync bookmarks, cookies, tabs, and site storage across browsers, and supports rule-based browser routing. All data is processed locally on your device with no cloud upload.
