In their own words
Screaming Frog SEO Spider
Screaming Frog SEO Spider crawls websites to audit more than 300 SEO issues and support improvements to search performance and user experience. It finds broken links and server errors, checks redirects, and flags page titles and meta descriptions that are missing, duplicated, or too long. For JavaScript-heavy sites, it can render pages with its integrated Chromium WRS, including sites using Angular, React, and Vue.js. Data extraction supports CSS Path, XPath, regular expressions, and custom JavaScript. The crawler connects to Google Analytics, Search Console, and PageSpeed Insights APIs, with link-metrics integrations for Majestic, Ahrefs, and Moz. Crawls can be scheduled, automated from the command line, exported to destinations such as Google Sheets, and compared across runs or between staging and production. The free version costs nothing and allows 500 URLs per crawl; saving crawls, configuration, and advanced features are restricted. The paid version costs $279 a year per licence, with unlimited crawl size subject to allocated memory and storage. It runs on Linux, macOS, and Windows.
Seodar
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.
