    What This Tool Checks

    • HTTP Status Codes — Whether each user agent receives 200 OK or is blocked
    • Response Headers — See exactly what headers your server returns
    • Response Time — How quickly your server responds to each bot
    • Content Preview — First 40 lines of HTML for successful requests

    Why Test ChatGPT User Agents?

    Many websites accidentally block GPTBot and ChatGPT-User through Cloudflare settings, WAF rules, or robots.txt configurations. If your site blocks these user agents, ChatGPT cannot access your content.

    This tool runs the exact same requests that GPTBot (training) and ChatGPT-User (live search) make to your site, showing you exactly what response they receive.
