Real-Time Tab Sync is a free Chrome extension developed by Petko Ditchev. It falls under the category of Browsers and is a useful tool for keeping your tabs synchronized across all your devices.

With Real-Time Tab Sync, any changes you make to your tabs are applied in real time on all of your computers that have the extension enabled. Whether you open a new tab, close a tab, or switch between tabs, the changes will be instantly reflected on all your devices.

To use the extension, you need to enable synchronization in the Chrome settings. Once enabled, you can easily toggle automatic synchronization on and off from the extension's icon.

It's worth noting that the extension does not work on Chromium, as the Chrome Sync API is no longer supported there. Additionally, the positions of windows and tabs are not preserved, and tab grouping is not yet supported. However, the extension works seamlessly with Chrome's "On startup" settings, merging the synced tabs with your chosen startup option.

Real-Time Tab Sync is a great tool for those who want to seamlessly transition between devices without losing their browsing sessions. It's a convenient and efficient way to keep your tabs organized and accessible across all your machines.
