Nirengi Log Analyzer
What Nirengi Log Analyzer is
Nirengi Log Analyzer is a free native macOS app for examining server logs and crawler activity. It reports on crawl budget, technical errors, coverage, content freshness, and bandwidth, and compares Googlebot with AI agents such as GPTBot, ClaudeBot, and PerplexityBot. Reports can identify 404 and 5xx responses, redirects, soft-404 candidates, parameter waste, and robots.txt issues. Sitemap URLs can be compared with observed traffic to spot uncrawled, orphaned, or neglected URLs. It supports Apache and Nginx logs, IIS W3C, AWS CloudFront, Cloudflare Logpush NDJSON, JSON Lines access logs, and AWS ALB logs. Filtered results can be exported as CSV, while a complete report can be shared as a single-file HTML document. The maker says selected files are processed locally in the macOS App Sandbox and that logs and results are not uploaded through the app. Version 1.0 requires macOS 14.4 or later and has no subscription or in-app purchase; the maker lists 41 reports across several analysis categories.
