Is It Taken?
Check if your startup name is taken across .com, .io, .co, .app domains (via official RDAP protocol) and X, GitHub, Instagram, and TikTok — all in one search.
Sample data shown. Run a real check above for your own name.
How It Works
Unified registry queries and profile probes executed simultaneously.
Domain check
We query RDAP — the official domain registration protocol used by registries — across .com, .io, .co, and .app instantly.
Handle check
We check whether X, Instagram, TikTok, and GitHub profile URLs for that name currently resolve.
One combined view
See everything in one place instead of checking four domain registrars and four platforms by hand.
Methodology Note: Domain results come from RDAP, the official registry protocol — reliable and accurate. Social handle results are estimated by checking whether a profile page exists at that URL, which is not an official API from any platform — treat these as a strong signal, not a guarantee, especially right before you commit to a name everywhere.
