DR Lens · Domain Rating in your toolbar

DR Lens puts the Ahrefs Domain Rating (DR) of every site you visit right into your toolbar icon. Free - one-minute setup with your own free Ahrefs API key. 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 For Domain Rating lookups, DR Lens sends the current site’s hostname and your Ahrefs API key to api.ahrefs.com. Your key and rating cache are stored on your device. If you click “Check on Ahrefs,” your browser opens Ahrefs’ checker with the hostname and campaign parameters in the link. Page paths, query parameters, and page content are not sent outside your browser. DR Lens has no in-extension analytics or telemetry. Localhost, IP addresses, and reserved local domains are filtered out. 📖 OPEN SOURCE Audit every line: https://github.com/kkomelin/dr-lens PERFECT FOR ✅ Sizing up competitors while you browse ✅ Qualifying link building prospects in seconds ✅ Vetting guest post offers and outreach emails ✅ Checking unfamiliar sites before you trust them CHANGELOG 1.2.0: Added a “Check on Ahrefs” link in the popup that opens the current domain in Ahrefs' Website Authority Checker. 1.1.0: ⚠️ Action needed: Ahrefs now requires a free API key, so ratings stopped working. Create a free account at ahrefs.com, generate a key under Account settings -> API keys, and paste it into the new extension settings - the popup will guide you. The key stays on your device and is sent only to Ahrefs. Domain Rating data by Ahrefs.
