In their own words
EdgeComet Log 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.
Screaming Frog SEO Log File Analyser
Screaming Frog SEO Log File Analyser is a desktop application for examining access logs and understanding search engine and AI bot activity. It installs locally and keeps log event data in a local database. It accepts Apache, W3C Extended, and Amazon Elastic Load Balancing logs, and can verify supported bots to identify spoofed requests. Reports cover crawled URLs, crawl frequency, response errors, redirects, bytes downloaded, and response times. Users can match imported data containing a URLs column against log activity, including crawls, directives, or external link data. Log files can be added by drag and drop, with analysis exported to CSV or Excel. The software can process millions of events, though capacity depends on hard drive space. It runs on Linux, macOS, and Windows. The free plan allows 1,000 log event lines and one project. The paid licence costs $139 per year and includes unlimited events and projects, subject to storage capacity. Free technical support is listed for both versions.
