About LeakRadar - Data Breach Checker
LeakRadar - Data Breach Checker instantly shows you how many leaked credentials exist for any website you visit.
How it works:
As you browse the web, LeakRadar automatically checks each domain against our database of 290 billion+ breached records collected from stealer logs, combolists and dark web dumps. A colored badge on the extension icon tells you at a glance whether the site has known credential leaks.
Click the extension icon to see a breakdown:
- Employees compromised — corporate accounts from the organization
- Third-parties compromised — vendors, agencies and partners
- Customers compromised — client accounts on the platform
Want to see the actual leaked data? Click "View Full Report" to open the full breach report on LeakRadar, where you can explore exposed credentials, password strength analysis and more.
You can also right-click any domain name on a web page and select "Check on LeakRadar" to instantly look it up.
Key features:
- Automatic breach check on every website you visit
- Color-coded badge: green (clean), orange (moderate exposure), red (high exposure)
- Detailed popup with employee, third-party and customer credential counts
- Right-click context menu to check any domain
- 24-hour local cache for fast performance
- No account required to see stats
- Zero data collection — we only call the LeakRadar public API for the domain you visit
