uatu

Uatu is a cross-browser extension that automatically synchronizes your open tabs to the cloud.

You start reading something on a mobile Safari and want to continue reading it on Google Chrome on your desktop?

Uatu helps you cases where you want to keep track of all your session across all browsers and platforms.

Uatu uses Google's Firebase to keep data and does not transmit it to any other service. You can encrypt all browser history by entering a passphrase.
