Netflix Party is a browser extension exclusive to Chrome. It allows users to synchronize Netflix video playback on multiple computers. Since it only needs to be installed on one computer, it’s probably one of the easiest to set up. Once you install the extension, navigate to Netflix and choose a film or TV show to watch.
Once it loads, pause your video and click on the red “NP” button in the top right of your browser window. This will generate a unique link that you can send to other people. Those folks will be directed to your “room” where they can watch your video in sync with you. Furthermore, Netflix Party allows users to engage with each other with a simple text chat interface.

Multi-platform and compatible with all the biggest video player apps out there (including VLC, KM Player and Media Player Classic), Syncplay is free and allows you to sync video streams with friends. You need to have the movies you want to watch stored locally on your hard drive, but once you set up, it’s just a case of you and your friend saying you’re ‘Ready to Watch’ and hitting the Play button.
