DR Lens — Domain Rating in your toolbar

About

DR Lens puts the Ahrefs Domain Rating (DR) of every site you visit right into your toolbar icon. Free, no account, no API key, zero setup.

Stop tab-switching to check domain authority. The number is just there in the toolbar, all the time.

👀 ALWAYS VISIBLE
The score is drawn into the toolbar icon itself. Browse normally, glance up, done.

🎨 COLOR-CODED TIERS
🟣 80+ Elite   🟢 60+ Strong   🔵 40+ Decent   🟠 20+ Building   ⚪ under 20 Low
One glance tells you what league a site plays in.

🔍 DETAILS IN ONE CLICK
Exact score, tier description, and a refresh button in a clean dark popup.

⚡ FAST AND POLITE
Ratings cache on your device for 24 hours and only the tab you are looking at triggers lookups. No wasted requests, no slowdown.

🔒 PRIVACY FIRST
Only the hostname (like example.com) ever leaves your browser. No full URLs, no page content, no tracking, no analytics. localhost and intranet hosts are never sent anywhere.
