Worker or JS tag
Cloudflare Worker (recommended) or a simple JS tag. Same four fields into the same Feed.
Track crawlers that hit your site — not visitors, not analytics. Free to signup, no credit card. See bots, then upgrade when you need more.
URL, IP, user-agent, timestamp. Enough to verify a bot and know when it hit. Nothing else.
Cloudflare Worker (recommended) or a simple JS tag. Same four fields into the same Feed.
Googlebot and other crawlers, checked against published IP ranges when we can. Spoofs get called out.
1 domain, 7-day visible data. Upgrade a domain when you need full Bots and URLs.
Useful bot data meant waiting on IT and sitting on PII. CrawlerLogs is the thin version: four fields at the edge, verified when we can, no dump.
It started as a problem John ran into doing SEO consulting for enterprise — crawl visibility without the log dump. Built as a CommaScale product.
