In their own words
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.
SEO4Ajax
SEO4Ajax uses dynamic rendering to make AJAX content visible to search engines and social networks. It can be configured on Apache, nginx, PHP, Java EE, Ruby, Python and Node.js servers, and supports frameworks including React, Vue.js, Angular, AngularJS, GWT, Ember and Backbone. The service says it can handle thousands or millions of pages without website code changes. Its REST API supports customization and automation, while a dashboard tracks bot activity, cache freshness, duplicates and broken links. SEO4Ajax caches snapshots, can capture inner links, and supports custom recache periods and email alerts for quota overages, scraping errors or unreachable websites. SEO reports flag indexing issues such as broken links, duplicates and invalid hreflang tags. The Developer plan is free, with 1,000 pages and 2,500 snapshots per month. Paid plans start at $29/mo (annual), and include email support at listed response times. The service is for business use, not personal, family or household use.
