Username Availability Checker

No automated checker can guarantee perfect accuracy. We inspect each platform's public profile page for strong signals like not-found pages and redirects, but private accounts, regional restrictions, and anti-bot protections can sometimes produce inconclusive results. When we're not confident, we label the result "Check manually" and give you a direct link to verify yourself.

Some platforms block automated tools with CAPTCHAs, login walls, or bot-detection pages. Rather than guess, we flag these as uncertain and provide the exact profile URL so you can confirm availability yourself in a few seconds.

Yes. The Username Availability Checker is completely free, requires no signup or registration, and gives you instant results for every check.

You can check X (Twitter), Instagram, LinkedIn, Facebook, YouTube, TikTok, Threads, Pinterest, and Bluesky, either one at a time or all together with the "Check all platforms" option.

Yes. Toggle "Check all platforms" before checking, and we'll scan all nine supported platforms, then show a summary and comparison table of how many are available for that handle.

We take the name you entered and generate common, brandable variations such as adding "official," "hq," "app," or "co," so you can quickly find an available and consistent handle if your first choice is taken.
