Intelligent bot detection with 143+ signatures, behavioral scoring, and Cloudflare-style management. See exactly who's crawling your site and take control.
Comprehensive signature database covering scrapers, AI training crawlers, vulnerability scanners, SEO tools, headless browsers, and spam bots. Updated regularly.
Each visitor gets a 0-100 suspicion score calculated from request headers, rate patterns, 404 frequency, missing assets, and request sequencing.
Confirms that Googlebot, Bingbot, and other legitimate crawlers are genuine by performing reverse DNS lookups and forward verification against known netblocks.
Inline action controls per bot signature: Block, Challenge, Allow, or Monitor. Manage every signature from a single table view with bulk actions.
Lightweight JavaScript challenge page for suspicious traffic. Legitimate browsers solve it automatically in under a second; headless bots and simple scripts fail.
Separate controls for search engine crawlers, social media bots, uptime monitors, and feed readers. Allow good bots while blocking the rest.
The Bot Detector uses a layered approach: first matching the User-Agent against known signatures, then running behavioral analysis, and finally performing rDNS verification for bots that claim to be from known search engines.
The scoring engine evaluates multiple signals to determine how suspicious a visitor is:
Each signature includes:
You can override the default action for any signature, and your custom actions persist across signature updates.
When a visitor claims to be Googlebot, Bingbot, or another known crawler, the Bot Detector performs a two-step verification process. First, it does a reverse DNS lookup on the visitor's IP address to get the hostname. Then it performs a forward DNS lookup on that hostname to confirm it resolves back to the same IP.
For Google, the hostname must end in .googlebot.com or .google.com. For Bing, it must end in .search.msn.com. Visitors that fail verification are flagged as impersonators and can be automatically blocked or challenged.
