FAQ
How does the availability check work?
We generate the profile URL for each platform. Click 'Check Availability' to open it β if you see a 404 or 'user not found' page, the username is available.
Why not check automatically?
Social platforms block automated username lookups. Manual checking via profile URLs is the most reliable method and avoids rate limits.
Should I use the same username everywhere?
Ideally yes β consistent usernames make your brand easier to find across platforms. If your first choice is taken somewhere, try adding underscores or periods.
