Screaming Frog

Screaming Frog SEO Spider is a desktop-based website crawler developed by Screaming Frog, a UK SEO agency. It’s considered a foundational tool for technical SEO audits, used by SEO professionals, agencies, and webmasters worldwide. The SEO Spider crawls websites — from small blogs to large ecommerce stores — to identify SEO issues like broken links, redirect errors, duplicate content, missing metadata, and crawl inefficiencies.
It supports advanced features like JavaScript rendering, structured data validation, API integrations (e.g., Google Analytics, Search Console), custom extractions, and site visualization.
