Website blocker for Chrome — enforcement when tracking is not enough
Three ways to reduce distractions
1. Hard blocklist
Add domains you never want during work. Visiting them redirects to a blocked page so the habit loop breaks at the door.
2. Daily time limits
Allow a budget (for example 30 minutes of YouTube). When the allowance is used, TimeFlow blocks further visits for the day — useful when total abstinence fails.
3. Focus mode
Start a timed session (25 / 50 / 90 minutes or custom). Distracting categories stay blocked until the timer ends — a browser-native deep work ritual.
How blocking works technically
- Add domains in Settings → Pro tools
- Rules are enforced with Chrome's declarativeNetRequest API
- Blocked navigations show a clear TimeFlow page with the reason
- Lists and limits stay on your device
Best workflow: measure, then block
- Install free TimeFlow and track for a few days (website time tracker).
- Check distraction insights and top sites — note the repeat offenders.
- Upgrade to Pro and block or limit only those domains.
- Protect mornings with focus mode before opening social tabs.

FAQ
Is the website blocker available on the free plan?
No. Blocking, daily limits, and focus mode are Pro features. Free TimeFlow still includes full local analytics and focus score.
Does blocking require broad host permissions?
TimeFlow Pro uses Chrome declarativeNetRequest with rules for domains you add. It does not need blanket access to rewrite every page.
Can I unblock a site later?
Yes. Remove it from the blocklist or end focus mode in Settings. You control the list on your device.
