FrameSyncX

About

Queue up videos without leaving the page.

FrameSyncX puts a one-click "Add to FrameSync" button right inside the video players and thumbnails you're already browsing. Spot something worth watching together? Drop it into your room's playlist and keep scrolling.

Works where you watch
YouTube, Twitch, and Vimeo — FrameSyncX detects videos automatically and lets you queue them from any of these platforms.

Multiple ways to add

Overlay button on the video player while you're watching (YT)
Circular + button on every thumbnail as you browse (YT)

Built for speed
Click the button, pick your room, done. The room picker shows both your own rooms and rooms you've joined, with playlist counts so you know what's queued. No extra tabs, no copy-pasting links.

Seamless login
Already signed in to FrameSync? The extension picks up your session automatically — no separate login required.

Privacy first
FrameSyncX doesn't track your browsing, collect analytics, or send data anywhere except frameshift.fun. It only reads the URL and title of video pages when you interact with it. No background activity, no telemetry, no surprises. Full details at https://frameshift.fun/privacy

Open and lightweight
Pure JavaScript, no bundlers, no dependencies, no bloat. Runs only on supported video sites and stays out of your way everywhere else.
