Synclify by Andrea De Masi

Watch ANY video streaming content in sync with friends straight from your browser.
Synclify is a browser extension for watching videos, films or any video content remotely with your friends, e.g., for movie nights with that long-distance special someone. It synchronizes video playback and volume, just share a room code!

This project is completely ad-free and open-source. You can sponsor this project here: https://github.com/sponsors/andreademasi

The extension is still in alpha so expect for something to now work and frequent updates. Send any bug or feedback here: https://github.com/openw2g/openW2G/issues or send an email at andreademasi80@gmail.com
