Green Checkmark
No extension needed for viewers. Anyone you invite can join and watch in sync instantly on any web browser, phone, tablet, or desktop app without installing anything.

Extension Frequently Asked Questions
Do all watch party members need the extension?
Not at all. Streams marked with play out-of-the-box for everyone with zero setup. Viewers only need the extension if the stream is marked with .
Which web browsers are supported?
The extension is built on Manifest V3 standards and is fully compatible with Google Chrome, Microsoft Edge, Brave Browser, Opera, Vivaldi, and any standard Chromium-based desktop web browser.
Does the extension collect my browsing history or personal data?
Never. PlayParty is engineered with privacy as a core foundation. All media detection runs 100% locally inside your browser window. No personal information, browsing history, login credentials, or account details are ever logged, stored, or transmitted to any external servers.
How does video stream auto-detection work?
When active, the extension injects a lightweight client-side media observer into your browser tab. It scans the page DOM for HTML5 video tags, iframe embeds, HLS (.m3u8) manifests, and DASH (.mpd) stream URLs. Once detected, a quick PlayParty button appears allowing you to launch a synchronized room instantly.
