Screaming Frog SEO Log File Analyser vs Seodar

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.

Seodar is a web and API website auditing service for technical SEO. It crawls sites, runs 195 checks, and orders fixes by expected impact. Audits cover indexability and crawling, metadata, content, links and media, and performance. Each audit receives a score out of 100 with its arithmetic shown, while findings are expressed as rates per page. The crawler decides per page whether JavaScript rendering is needed based on script weight and reports what rendering found. Accessibility checks use axe-core against WCAG 2.0, 2.1, and 2.2 at levels A and AA on a rendered sample; Seodar says this is not compliance certification. Connections include Cloudflare, Google Search Console, Google Analytics, and Bing Webmaster Tools with read-only access. A read-only API and MCP server query audit data. SeodarBot identifies itself, follows robots.txt and Crawl-delay, and pauses between requests. The free plan covers one site and 200 pages per crawl; paid plans start at €29/mo.
