Focus site blocker for Chrome

Blinders is a free Chrome extension that blocks distracting websites during focus sessions. Add the sites that derail you (social media, news, video), start a timer, and they won't load until you're done. It uses Chrome's built-in blocking, so it's fast and private — your list never leaves your browser.

How does it work?

Click the Blinders icon, add sites like twitter.com, pick a focus length, and hit Start. Those sites are blocked until the timer ends or you stop the session.

Is it free?

Yes — block up to 3 sites with 15/25/50-minute sessions, free. A one-time Pro upgrade adds unlimited sites and 90-minute sessions.
