Watch2Gether is a website where you paste a YouTube or Vimeo URL and everyone in the room watches it together. PartyStream is a website where one person shares a video file from their computer or their screen, and everyone watches the stream. The distinction sounds small, but it changes what you can watch and how it gets to you.
The short version
Use Watch2Gether if you want to watch YouTube, Vimeo, or other web video links together. It is built for that and does it well.
Use PartyStream if you want to watch your own video files, share your screen, or watch something that is not available as a simple web video URL. Also use it if you want peer-to-peer streaming with no server in the middle, or if you want guests to join without seeing ads on the watch room itself.
How each one works
Watch2Gether creates a shared room with a video player. You paste a URL (YouTube, Vimeo, Dailymotion, SoundCloud, and others), and the room embeds that video. Everyone in the room sees the same embedded player, and play/pause/seek is synced. The video comes from the original platform, not from Watch2Gether's servers.
PartyStream creates a room where one person (the host) picks a video file from their computer or shares their screen. The host's browser encodes and streams the video directly to each guest over WebRTC. The video never touches PartyStream's servers. Guests see the host's stream, not an embedded player.
Video sources
This is the biggest difference. Watch2Gether works with web video URLs from supported platforms. If the video is on YouTube, Vimeo, or another supported site, you paste the link and it works. If the video is a file on your computer, Watch2Gether cannot play it.
PartyStream works with files on the host's computer (MP4, WebM) or a screen share (any browser tab or desktop). If you have the file, PartyStream can stream it. If the video is on YouTube, you can screen-share the tab, but it is less elegant than Watch2Gether's native embedding.
Sync and playback
Both sync playback. Watch2Gether syncs play, pause, and seek on the embedded player. Anyone in the room can control playback. PartyStream syncs play, pause, and seek, but only the host controls playback. This prevents accidental skips but means guests cannot pause on their own.
PartyStream also has a queue for multiple files with auto-advance, which Watch2Gether does not have in the same way. Watch2Gether has a playlist of URLs, which serves a similar purpose for web videos.
Chat and reactions
Both have text chat. Watch2Gether has a chat sidebar with text messages and emoji. PartyStream has a chat sidebar with text messages, floating emoji bursts that animate across the screen, a full emoji picker, GIF search, and optional voice chat. PartyStream's chat is more feature-rich for reactions.
Privacy
Watch2Gether rooms are publicly discoverable by default (there is a room search). You can set a password, but the default is open. The video comes from the original platform (YouTube, Vimeo), so that platform's tracking and ads apply. Watch2Gether also shows ads in the room itself on the free tier.
PartyStream rooms are private by design. There is no public directory, no search, no discovery. Only people with the 8-character code or invite link can join. Video streams peer-to-peer, so no server sees it. No accounts, no ads, no tracking beyond standard analytics on the site itself. See our privacy deep dive for more.

When to use which
Use Watch2Gether when:
- You want to watch YouTube videos together.
- You want to watch Vimeo, Dailymotion, or other web video content.
- You want anyone in the room to be able to add videos to the playlist.
Use PartyStream when:
- You want to watch your own video files, not web video URLs.
- You want to screen-share a browser tab or desktop.
- You want a private room with no public discovery.
- You want peer-to-peer streaming with no server in the middle.
- You want no ads on the watch room itself.
- You want voice chat alongside the video.
They complement each other. If you are watching YouTube, Watch2Gether is more convenient. If you are watching your own files or want privacy, PartyStream is the right tool.
