The record

Purpose: Analyzes server access logs to show crawler activity, crawl-budget waste, AI crawler traffic, and likely crawler impersonators.
Log formats: It auto-detects nginx, Apache, IIS/W3C Extended, and JSON logs including Cloudflare Logpush.
Local processing: Log parsing runs in the browser, and pasted or uploaded logs are not sent to the server.
Optional network check: The optional suspicious-IP spot-check sends a single IP to the verifier API for reverse-DNS and ASN lookup.
Privacy detail: Anonymous run-level outcome counters may be used for aggregate research, with no URLs, domains, IPs, or identifiers included and no statistic released below 100 runs.
Crawler verification: It compares request IPs with crawler operators’ published ranges and marks crawlers without checkable ranges as unverifiable.
Reports: Reports include crawl budget by bot and section, crawler-by-page-type matrix, wasted URLs, and daily trends when logs contain timestamps.
Recommendations and export: It provides ranked recommendations with copy-paste robots.txt lines and CSV exports for bots and wasted URLs.
Expected URL comparison: Users can supply a sitemap or expected URL list to compare against crawler requests.
Limits: It can only analyze requests present in the log and does not report indexing outcomes or explain why a crawler selected a URL.
Verification limit: IP-range matching may miss an impostor using a genuine crawler IP, and crawlers without published ranges cannot be distinguished by range matching alone.
Support: The page offers bug reports through a private triage queue and feature requests that are reviewed before appearing publicly.
Audience and use cases: The maker describes use cases including measuring crawler activity, finding crawl-budget waste, comparing AI and search crawlers, and investigating possible bot spoofing.
