Is the name free?

Check business names against the ten most popular domain endings, and see whether a company, app or project already uses them.

Press Enter or type a comma after each name. Up to 10.
Ten domains
.com, .net, .org, .ai, .be, .eu, .dev, .io, .app, .co: DNS first, then the registry itself (RDAP, or WHOIS for .be, .eu, .io and .co).
Who uses the name
Exact matches in a web search and among known companies and brands, App Store apps, GitHub projects, npm packages and Hacker News launches.
One verdict
Free on all ten? One check mark. Otherwise you see what is free and what is taken, and whether anyone notable uses the name.

A quick first check, not legal advice: look up trademarks before you commit to a name. The web search uses Ceramic's index through Cloudflare, not Google, so Google and trademark searches are links you open yourself.
