Teleparty, previously known as Netflix Watch Party, is a browser extension that lets users synchronize their streaming experience and remotely watch movies, TV shows, and videos with friends. Teleparty supports streaming platforms like Netflix, YouTube, Hulu, Disney+, HBO Max, and Amazon Prime. The extension ensures synchronized playback, allowing actions like pausing and skipping ahead to apply to all participants. Users can communicate through a chat sidebar, choose user icons and names, and the host can control playback and chat settings. Teleparty is easy to install on Chrome, Edge, or Opera browsers and can support watch parties with over 100 participants, offering a fun way to watch content together and interact in real-time.
