Tenure - Zero-Click Website Age Checker

Tenure shows you how long any website has been registered, helping you avoid scams and phishing sites before you ever click a link. Fast, distraction-free, and privacy-first.

See website ages right in your search results

Tenure overlays domain registration age directly in your Google and DuckDuckGo search results with no clicking required. Spot newly registered domains at a glance and skip the sketchy ones entirely. Works great alongside tools like uBlacklist for keeping your search results clean.
