namechan — WHOIS Lookup & Domain Availability Checker

Look up any domain without leaving the page you're on. namechan puts WHOIS details, domain availability and prices in Chrome's side panel. DOMAIN DETAILS (WHOIS / RDAP) Registration status, registrar, registration and expiry dates, domain age, nameservers, status codes and the raw WHOIS record, where the registry publishes them. Open the panel on a site to look up its domain, or type a different one. OTHER TLDS Check the same name across .com, .ai, .io and the other TLDs (domain extensions) you choose. See which are available, compare first-year and renewal prices, show available names only and sort by price. Edit your TLD list in settings. BULK DOMAIN CHECK Paste a list of domains, filter the results by available or taken, and export them as CSV or JSON. Signing in lets you check longer lists. MADE FOR BROWSING Opens beside the page from the toolbar icon. Light and dark themes follow your system. Available in English, Simplified Chinese, Traditional Chinese, Japanese, Portuguese and Russian. No account needed. Signing in with a namechan account raises your lookup limits. Availability, WHOIS fields and prices come from registries and pricing providers; confirm the final price and availability with the registrar before you buy. PRIVACY The extension sends the domains you look up to namechan.com to get results. It reads only the address of the tab you open it on, never the page content. Settings and cached results stay in your browser; if you sign in, a sign-in token is stored there too. Website: https://namechan.com Privacy policy: https://namechan.com/privacy
