SEO server log analysis

See what crawlers actually do.

Nirengi turns sensitive infrastructure data into evidence without sending it to the cloud.

Googlebot and AI crawlers

Compare search-engine crawling with GPTBot, ClaudeBot, PerplexityBot and other known AI agents.

Errors and crawl waste

Find 404, 5xx, redirects, soft-404 candidates, parameter waste, asset crawling and robots.txt violations.

Coverage and freshness

Compare sitemap URLs with observed traffic to discover uncrawled, orphaned or neglected pages.

Verified bot identity

Use reverse and forward DNS checks to distinguish supported verified crawlers from spoofed user agents.

Large-file engine

Process millions of lines in parallel and move aggregation to disk when the working set may exceed safe memory.

Portable reports

Export individual CSV files or a self-contained HTML report without a cloud account.
