How It Works

The application checks Steam profile URLs (https://steamcommunity.com/id/<username>) to determine if a username is available. Steam returns different responses for existing vs. non-existing profiles, which the app analyzes to determine availability.

Note: This tool checks Steam profile URLs. Results may not be 100% accurate for account creation, as Steam may have additional restrictions or reserved usernames.

Security Features

• Input sanitization to prevent injection attacks
• HTML escaping to prevent XSS vulnerabilities
• URL validation for profile links
• Security headers (CSP, X-Frame-Options, etc.)
