Overview

Keep the same open tabs in Brave and Safari. End-to-end encrypted, through a hosted or your own server.

Cross-Tab-Sync keeps one shared set of open tabs between your browsers: Brave, and Safari on macOS (Safari uses the separate Cross-Tab-Sync app). Click Start syncing, copy the invite link, and paste it into the extension in your other browser. Tabs you open, navigate or close on the browser you are using appear on the other one. Closing a window or quitting never deletes shared tabs; only closing an individual tab does. Tab addresses are encrypted in this browser before they are sent. The server only stores ciphertext. The key travels only inside your invite link. No account, no analytics, no ads. Uses the free hosted server by default; you can run your own with Docker (open source, MIT): https://github.com/KaanEmec/cross-tab-sync
