Teleparty, Watch2Gether, Kosmi or Futari: which one to watch together?
Four tools, three ways to watch together. Here is how they compare on what matters for a series or anime evening, from their own websites.
Three ways to watch together
- Sync each person's own stream: Futari and Teleparty. Everyone plays the video on their own account, in full quality, and the extension keeps them in step.
- A shared room with a built-in player: Watch2Gether, for YouTube, Vimeo, Dailymotion and SoundCloud, with an extension for streaming sites.
- Screen sharing or a shared virtual browser: Kosmi. One person shows the video to the others; free screen sharing goes up to 720p.
