About

Screaming Frog SEO Spider is a website crawler for technical SEO audits and user experience checks. It can identify broken links and server errors, review redirects, and flag missing, duplicated, or overly long page titles and meta descriptions. Its integrated Chromium WRS renders JavaScript pages, including sites using Angular, React, and Vue.js. For custom extraction, it supports CSS Path, XPath, regular expressions, and custom JavaScript. The crawler connects to Google Analytics, Search Console, and PageSpeed Insights APIs, and lists link-metrics integrations for Majestic, Ahrefs, and Moz. Teams can schedule crawls, export data to locations such as Google Sheets, automate through the command line, and compare crawl results or staging with production. The free version requires no signup or email capture but is limited to 500 URLs per crawl and restricts saving crawls, configuration, and advanced features. The paid licence costs 279.00 USD per year per licence and has an unlimited crawl limit subject to allocated memory and storage. The software supports Linux, macOS, and Windows.
