Domain checker for Chrome
Check any name without leaving the page you're on.
Download the extension (.zip)What it does
- Toolbar popup: type a name and see .com, .net, .org, .io, .ai, .co, .app and .dev at once.
- Right-click: select any text on a page, then choose "Check domain availability".
- Address bar: type
df, a space, then a name. - One click to ideas: jump to hundreds of brandable alternatives on DomainFinch.
Who it's for
Founders brainstorming a name in a document, marketers checking a campaign idea, developers naming a side project, and domain investors scanning lists. Anywhere you see a word or phrase, you can check it as a domain in two clicks.
Private by design
Lookups go straight from your browser to Cloudflare's public DNS. The extension has no account, no analytics and no data collection, and only asks for the permissions it needs: the right-click menu, and access to the DNS services that answer "does this domain exist?".
