Chrome extension · v5.0.1

Watch reactions and the show in perfect sync

Install the React Sync extension, then use Watch to line up your reaction video with streaming content—side by side, PiP, or stacked. Built for creators and fans who want a real watch-along.

Works in Chrome and Chromium-based browsers that support the Chrome Web Store.

Why React Sync

Instant sync

Master controls, sync points, and sync lock keep both players aligned without guesswork.

Major streamers

Netflix, Disney+, Crunchyroll, Prime Video, Max, and more—using your own subscription and our extension bridge.

Privacy-minded

Sync runs in your browser; we don’t host shows or replace your streaming apps. See our Legal page for details.
