EdgeComet Log Analyzer vs Log File Bot Traffic Cost Analyzer

EdgeComet Log Analyzer records search-engine and AI-crawler requests together with the page state each bot received, helping teams examine crawling and indexing. It covers bots such as Googlebot, Bingbot, GPTBot, ClaudeBot, and Perplexity. For each request, it can show the title, meta description, canonical, robots directives, hreflang, and structured data in the HTML served to the bot. Requests are classified as valuable, questionable, or wasted, with causes such as errors, redirects, blocked URLs, non-canonical pages, and render errors. Bot identities are checked against published IP ranges, with 35 real identities supported for verification. Collection requires routing bot requests through EdgeComet via a CDN or proxy; it does not import or parse log files. Supported routing platforms include Cloudflare Workers, Fastly VCL, AWS CloudFront Lambda@Edge, and nginx. The product also offers an HTTP API, an MCP server, and an Apache-2.0 open-source rendering and caching core that can be self-hosted. Professional costs $99 a month. There is no free plan; a 14-day trial is listed.

Log File Bot Traffic Cost Analyzer examines server logs to summarize AI bot traffic, estimate costs, measure crawl budget, and prepare edge rules. It lists 127 bot signatures and 18 browser patterns, with bandwidth, IPs, and time to first byte by category. Verification uses vendor IP data, TLS, cloud ASN heuristics, and behavior; heuristic results are labeled low confidence, and optional reverse DNS through 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 remaining 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 described as exact, and BigQuery is for 50 GB and above. It is free, MIT-licensed, and supports CSV and PDF downloads plus generated policy files.
