How to check if a business or app name is already taken
Trademarks, domains, the web, social media and GitHub in one check, with a traffic-light verdict your AI assistant can use.
Where to look
Trademark offices (EUIPO/TMview in Europe, WIPO Global Brand Database worldwide, SIC in Colombia), domains including industry variants (name+app, name+vet), the web, social handles, and for software, GitHub and npm. What matters is the same name in the same industry: an identical name in an unrelated class usually coexists.
Do it in seconds
Namli checks all of these at once and returns 🟢 free, 🟡 similar or 🔴 taken, with evidence links and dates. It is also an MCP server, so Claude, ChatGPT, Cursor and other assistants can verify every name before suggesting it.
Not legal advice
This is an automated first filter of public sources. Before registering a trademark, consult an IP lawyer.
