Username Checker
Verify a handle across 14 developer and creator platforms
What it does
Check whether a username exists across 14 developer and creator platforms, including GitHub, YouTube, Behance, Flickr, SoundCloud, HackerOne, Bitbucket, Dev.to, Goodreads, Blogspot, Itch.io, Gumroad, and Buy Me a Coffee. Every platform was verified live by comparing a real handle against a nonsense one, so a JavaScript-only or always-200 site can't fake a match. No login, no API key.

Common questions
Which platforms does this check? +
14 developer and creator platforms including GitHub, YouTube, Behance, Flickr, SoundCloud, HackerOne, Bitbucket, Dev.to, Goodreads, Blogspot, Itch.io, Gumroad, and Buy Me a Coffee.
How does it avoid false positives on platforms that always return 200? +
Each platform was verified live by comparing a real, known handle against a nonsense one; only platforms that return genuinely distinct responses for real-versus-fake handles are included, so a JavaScript-only or always-200 storefront can't fake an existence match.
Do I need an API key or browser? +
No. It's direct HTTP fetches per platform: no authentication, no headless browser, no proxy.
What are the main use cases? +
Checking handle availability across platforms before committing to a brand or project name, verifying a claimed username for a candidate or contact actually exists, and OSINT workflows that need a fast multi-site existence check instead of visiting each site by hand.
How does pricing work? +
Pay-per-event at $0.02 per username checked, counted once per username across every platform requested, not per platform. A run with no usernames is never charged.
