Check if a username is available on Mastodon
Type a name to see whether it is free on Mastodon, a social network. Free, no sign-up: Nomok also checks 70 other platforms and domain names at once.
How Nomok checks Mastodon
Nomok queries Mastodon live and tells an existing account from a free name using the platform's response (page or public API). The result is reliable, but a free name can still be reserved or banned by Mastodon's rules.
Naming rules
Up to 30 characters: letters, numbers and underscores. Names are per instance; Nomok checks the main instance, mastodon.social.
