Check username availability across 7 platforms in one click.
Username Checker helps you quickly check whether a handle is available on Instagram, TikTok, YouTube, X, Threads, Bluesky, and GitHub. Paste a username once and get instant results without signing up or waiting. If the handle is taken, the tool also suggests alternative usernames. It’s a simple way to compare availability across major platforms before you claim a name for your brand, project, or personal account.
