SecureMyName Brand Checker

The fastest way to test whether a brand name has a domain available — across seven TLDs at once. Highlight any word on any webpage, right-click, and pick "Check as a brand name". The extension queries Unstoppable Domains for seven TLD variants in parallel and shows you the answer in under a second: 🟡 LISTED on UNSTOPPABLE DOMAINS → click straight through to buy 🔴 REGISTERED · NOT FOR SALE → already owned; don't waste time 🟢 AVAILABLE TO REGISTER → click to Register it at UNSTOPPABLE DOMAINS Below the availability grid, the popup surfaces the closest matches from SecureMyName.com's curated 1,765+ premium domain portfolio — so even when your exact name's taken, you've got brandable alternatives one click away. WHO IT'S FOR • Founders and product managers picking a brand name • Domain investors testing brandability ideas • Web3 / SaaS / AI / cybersecurity / fintech operators who care about TLDs beyond .com • Anyone who wants a single tool instead of seven tabs WHAT IT CHECKS The 7 TLDs are .com .net .org .io .ai .co .xyz — the most common premium endings supported by Unstoppable Domains' marketplace. Each lookup combines two signals: Unstoppable Domains' public lander API (for marketplace listings + price) and Cloudflare's public DNS-over-HTTPS resolver (for definitive registration status). No API keys, no logins, no remote code. DEFAULT DISPLAY: SIDE PANEL By default the extension opens in Chrome's right side panel — keep it open while you browse and right-click on any name across the web to check it instantly. A small toggle in the footer switches to popup-window mode if you prefer. WHAT IT DOESN'T DO • It doesn't check registrar availability outside Unstoppable Domains' supported TLDs. • It doesn't run any tracking, analytics, or telemetry inside the extension. • It doesn't take ownership of your selection or send it anywhere except UD's public API. PRIVACY Settings stored locally via chrome.storage.local. The only network requests are to api.unstoppabledomains.com (public marketplace API). No user data attached to any request. Full privacy policy: https://securemyname.com/privacy.html PERMISSIONS • contextMenus — to add the right-click "Check as a brand name" item. • storage — to cache the SecureMyName.com portfolio locally so the popup is instant. • sidePanel — to open the brand-checker UI in Chrome's side panel. • host_permissions: https://api.unstoppabledomains.com/* — UD marketplace API. The extension does NOT request access to your browsing history, your tabs, your bookmarks, your cookies, or any third-party site.
