Log File Bot Traffic Cost Analyzer

Summary

Log File Bot Traffic Cost Analyzer examines server logs to show AI bot traffic, estimated costs, crawl budget, and possible edge rules. It categorizes traffic with bandwidth, IP, and time-to-first-byte details, using 127 bot signatures and 18 browser patterns. Bot verification draws on vendor IP data, TLS, cloud ASN heuristics, and behavior; heuristic results are labeled low confidence, and optional reverse DNS via DoH is listed. Cost estimates use measured bytes and CDN pricing presets, with copyable rules for Cloudflare, Fastly, and AWS. Other modules cover crawl traps, rendering gaps, bot-versus-human performance, traffic bursts, 404 clusters, a GSC overlay, and security anomalies. Inputs include JSON, JSONL/NDJSON, Apache Combined, Nginx, W3C Extended, AWS ALB, Cloudflare Logpush, and gzip files. The project describes processing as client-side, with logs staying on the user's machine. Its only stated network request is for a demo file the user chooses to load. Browser analysis under 500 MB is sampled triage; CLI analysis from 500 MB to 50 GB is exact, and BigQuery is listed for 50 GB and above. The free, MIT-licensed project offers CSV and PDF downloads and generated crawler policies.

Who it is for

It suits people who need to inspect server logs privately, including quick triage where logs cannot leave the machine. The documented analysis options vary with log size.
