Free Domain Age Checker

Free Domain Age Checker shows you how old any website is — in one click. Open the popup on any site and instantly see its domain age in years, months and days, plus the registration date, expiry date, registrar, IP address and name servers. Whether you're researching a website before you trust it, vetting a domain you want to buy, doing SEO research, or just curious, this is the fastest way to check a domain's age and WHOIS details without leaving the page. 100% FREE: no sign-up, no account, no ads, no premium tier, no tracking. ⏹️ WHAT YOU GET • Exact domain age - years, months and days since registration • Expiry countdown - "Expiring in X days" so you can spot domains about to lapse (or already expired) • Registration (created), last-updated and expiry dates • Registrar name • Server IP address with one-click copy • "Hosted on" - the hosting company or CDN that owns the server's IP (e.g. Cloudflare, Amazon, Hetzner) • Name servers with one-click copy • Works on any http(s) website, including subdomains (blog.example.co.uk is checked as example.co.uk) • Clean, simple popup that opens at the same size every time, no scrolling ⏹️ WHY CHECK DOMAIN AGE? • Spot scams and phishing: brand-new domains are a common red flag for fake shops and impersonation sites • SEO and link building: older, established domains are often a useful trust signal when evaluating sites and backlinks • Buying or selling domains: verify the real registration date and when it expires • Competitor and market research: see how long a competitor's website has existed • Due diligence: confirm a business website's history before you share personal or payment details ⏹️ HOW IT WORKS Click the toolbar icon on any website. The extension reads only the domain name of the current tab and looks it up using RDAP - the official, modern replacement for WHOIS - directly from the domain's registry. For domain endings that don't support RDAP it falls back to a free public WHOIS service. Results appear in a second. ⏹️ PRIVACY FIRST • No data collection, no analytics, no accounts, no ads • Only the domain name and the website's public server IP (never the full URL, page content, cookies or history) are looked up, and only when you open the popup • Uses just the "activeTab" permission - it can't read your tabs in the background ⏹️ WORKS IN YOUR BROWSER Available for Google Chrome, Microsoft Edge, Mozilla Firefox, Opera and Brave. ⏹️SUPPORT THE PROJECT This extension is free and always will be.

Some registries hide or omit certain fields (for example expiry dates or registrar details), and transferred or re-registered domains may show a newer creation date.
