Domains

Checked via RDAP — the domain registries' own public lookup.

Results come from probing public profile pages — no logins, no APIs. Some platforms (Instagram, Facebook, X, TikTok) block anonymous checks; when that happens the card shows Check manually ↗ — it means the platform wouldn't say (not that the name is free or taken), and the link opens the profile URL so one click in your browser settles it. Always confirm on the platform before committing to a name.
