Website Bot Test Tool
Check how your website responds to common bots and headless clients.
Run a full bot behavior check
This test sends many controlled requests with common bot, crawler, scanner and exploit-like signatures to show how your website reacts.
Large bot matrix
Checks browsers, headless clients, CLI tools, crawlers, social bots, LLM bots and scanners.
Exploit probes included
Adds harmless exploit-like GET probes for SQLi, traversal, XSS and similar patterns.
BYB diagnosis support
Reads optional BYB diagnosis headers when your protection sends them.
Page Description
This tool sends test requests to your domain with various user-agents (e.g., Googlebot, GPTBot, curl) to see if they are blocked or allowed.
Results include HTTP status, redirects, response time and an indicator whether the request seems blocked or allowed.
Use 'no referrer' and 'no cookies' to simulate stricter bot-like behavior.
Tip: Real search engine bots should be validated by reverse DNS, not by user-agent alone.
