The record

Purpose: Nirengi analyzes server logs to show crawler behavior, errors, crawl budget, coverage, content freshness and bandwidth.
Intended users: The maker describes it as a native macOS app for technical SEO specialists, consultants, publishers, SaaS teams and e-commerce teams.
Crawler analysis: It compares Googlebot with GPTBot, ClaudeBot, PerplexityBot and other AI agents.
Error reports: It can identify 404s, 5xx responses, redirects, soft-404 candidates, parameter waste and robots.txt problems.
Coverage reports: It compares sitemap URLs with observed traffic to find uncrawled, orphaned or neglected URLs.
Bot verification: Reverse and forward DNS checks help distinguish supported search bots from spoofed traffic.
Report count: The product page lists 41 reports across crawler identity, AI crawlers, crawl budget, technical errors, coverage and freshness, visitor traffic and category analysis.
Log formats: Supported formats include Apache and Nginx logs, IIS W3C, AWS CloudFront, Cloudflare Logpush NDJSON, JSON Lines access logs and AWS ALB logs.
Exports: Users can export filtered results as CSV or share a complete report as a single-file HTML document.
Local processing: Selected files are processed locally in the macOS App Sandbox, and the maker says logs and analysis results are not uploaded through the app.
Data collection: The privacy policy says the app requires no account and contains no advertising, analytics, tracking pixels, telemetry or crash-reporting SDK.
Network access: Network requests are limited to user-initiated sitemap or robots.txt retrieval, DNS bot verification and opening product or support links.
Support: The developer offers direct support by email or phone and asks users not to send production logs before removing confidential information.
Performance example: The maker reports processing a 15.4 GB production log in 40 seconds on an Apple M4 Mac with 16 GB of memory, noting results vary by hardware and settings.
