Focuser — Website Blocker od Aadesh Yadav

Focuser is a free, open-source website blocker that helps you stay focused and productive by blocking distracting websites.

How It Works
Focuser works together with the Focuser desktop application to enforce your blocking rules. Create custom block lists, add websites you want to block, and Focuser will replace those sites with a motivational focus page — keeping you on track.

Key Features
- Block any website by domain, URL path, keyword, or wildcard pattern
- Custom block page displayed instead of distracting content
- Real-time blocking across all open tabs
- Multiple block lists for different focus sessions (work, study, etc.)
- Block the entire internet with specific exceptions for allowed sites
- See how many sites are blocked and how many distractions were prevented today
- Quick-add any site to a block list directly from the popup

Privacy First
Focuser processes everything locally on your device. No data is ever sent to external servers. No tracking, no analytics, no accounts required.
