Check if a username is available on Roblox
Type a name to see whether it is free on Roblox, a gaming platform. Free, no sign-up: Nomok also checks 70 other platforms and domain names at once.
How Nomok checks Roblox
Nomok queries Roblox 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 Roblox's rules.
Naming rules
Between 3 and 20 characters: letters, numbers and at most one underscore, not at the start or end. Nomok uses the official Roblox sign-up validation.
