Check Username Availability Across 80+ Platforms

Our tool checks username availability across 80+ platforms by sending requests to public profile URLs. We analyze the response codes and page content to determine if a username is available, taken, or unknown. Since CORS blocks direct browser requests, we use a server-side PHP endpoint to perform these checks.

CORS (Cross-Origin Resource Sharing) blocks most cross-site requests. We use a small PHP endpoint to fetch profile pages server-side, which allows us to check availability across multiple platforms that would otherwise block browser-based requests.

Without official APIs, no tool can be 100% accurate. We use status codes and page signatures to determine availability, but some services always respond with 200 or show bot protection, which may result in "Unknown" or "Unverifiable" results. For critical platforms, we recommend manual verification.

We support 80+ platforms including Instagram, TikTok, Twitter/X, YouTube, Facebook, LinkedIn, GitHub, Steam, Twitch, Discord, and many more. Our platform list includes social media, gaming, developer, creative, video, and music platforms. Check our platform updates page for the latest additions.

Most checks complete within 5-15 seconds. The time depends on the number of platforms being checked and their response times. We check all 80+ platforms simultaneously to provide fast results.

"Unknown" means we couldn't reliably determine if the username is available or taken. This often happens when platforms use bot protection, login walls, or dynamic rendering. "Unverifiable" indicates platforms we cannot check due to technical limitations. In both cases, we recommend manually checking the platform.
