Site Blocker
Block the sites that steal your day
Pick the site that gets you most. Each guide shows how to block it in Chrome in about a minute, and smarter options when you still need part of it: hide just the feed, block it during work hours, or give yourself a daily allowance.

How blocking works in ZenTab
- Blocked sites show a calm page with your streak and a button to start focusing, not a guilt trip.
- A site covers all its subdomains, so blocking reddit.com also blocks old.reddit.com.
- Blocking is always on, not just during focus sessions. With Pro, schedules decide when.
- Five ready-made packs (social media, video, news, shopping and gaming) or your own list.
Frequently asked questions
How many sites can I block for free?
Ten at a time, with no time limit. ZenTab Pro removes the limit and adds page-level rules, allowlist mode, schedules and daily time limits for $10 once.
Can I block just part of a site?
Yes, with Pro. Add a page rule like youtube.com/shorts or reddit.com/r/all, and the rest of the site keeps working. Or use Feed Eraser to hide a site's feed without blocking anything.
Does blocking work in Incognito?
Yes, once you allow it: open chrome://extensions, click Details under ZenTab and switch on Allow in Incognito.
Will blocked sites know I'm blocking them?
No. ZenTab works entirely inside your browser and never sends your blocklist or browsing to anyone.
