How it works

Start a watch party in three steps

No downloads, no sign-ups, no upload bar to wait on. Pick a file, share a code, and watch together.

01
Pick your video
Drop a video file from your computer. PartyStream streams it straight to your friends — no upload, no waiting.
02
Share the room code
Send the 8-character room code or invite link to your friends. They enter a name and join instantly — no account, no app to install.
03
Watch together, in sync
Play, pause, and seek stay in sync for everyone. Chat and react live in the sidebar. It's movie night, wherever you all are.
Features

Everything an online watch party needs

Built for real movie nights, not a demo — every feature is designed around the experience of watching together.

Instant streaming, no upload
Your video streams straight from your browser to your friends — no upload, no waiting. Guests see it the moment you press play.
Perfect real-time sync
Every play, pause, and seek is shared instantly across the room. Everyone watches the same moment, so you stay perfectly in step.
Live chat & reactions
React in the moment with emoji reactions on messages. Chat runs alongside the video in a dedicated panel — never covering the screen.
Private rooms
Rooms are identified by an 8-character code only you share. No public listings, no discovery — only people you invite can join.
Quality each guest controls
Each guest picks Auto, High, Medium, or Low quality — or lets it adjust to their connection. The host sends only what each guest asks for.
Works on any browser, anywhere
Runs entirely in your browser on Chrome, Firefox, and Safari — no installs, no extensions. It works across different networks and locations, so friends anywhere can join.
Use cases

Who watches together

PartyStream is built for real moments when people want to share the experience of watching — not just the file.

Long-distance movie nights
Watch the family film with relatives across the country. Everyone laughs at the same moment — no awkward "wait, where are you?" messages.
Study groups & lecture recordings
Share a recorded lecture with your study group. Pause to discuss, rewind to rewatch, and chat notes in real time without anyone falling behind.
Gaming clans reviewing VODs
Review match footage together. One player hosts, everyone watches the same replay, and the group chats strategy in real time.
Remote teams reviewing video
Review client deliverables, ad cuts, or product demos together as a distributed team — with timestamped chat feedback in the sidebar.
