What is ClaudeBot Checker?
ClaudeBot is Anthropic's web crawler used to ground Claude's answers and to collect training data. If ClaudeBot is blocked, Claude will not cite your content. The ClaudeBot Checker inspects your robots.txt, isolates ClaudeBot-specific rules, and gives you a one-click fix to allow ClaudeBot safely.
How it works
Enter your URL
We fetch your robots.txt and look for User-agent: ClaudeBot and anthropic-ai rules. Either can block Claude independently.
Verify crawlability
We check for path-level Disallow rules and known edge-level blocks. Anthropic rotates IPs so we also check for IP-based rate limits.

ClaudeBot Checker FAQ
Anthropic uses both User-agent strings. ClaudeBot is the older identifier; anthropic-ai is the newer one. Our checker tests both so you are never surprised by a partial block.
