Technical SEO

Desktop crawler that audits technical SEO issues across unlimited pages

Compare →Visit screamingfrog.co.uk/seo-spider ↗

Overview

Screaming Frog SEO Spider has been the default technical SEO auditing tool since 2010. Built by a small UK team, it remains the most widely used desktop crawler among SEO professionals for one simple reason: it works consistently and finds the issues that matter. Unlike cloud-based alternatives, it runs locally on your machine and can crawl unlimited URLs with a paid license.

The tool excels at fundamental technical audits — broken links, redirect chains, missing meta tags, duplicate content, and server response codes. Its strength lies in comprehensive data extraction and flexible configuration options that let experienced users dig deep into specific technical issues. While newer tools like Sitebulb offer prettier reporting and Botify provides enterprise-scale log analysis, Screaming Frog remains the reliable workhorse for day-to-day technical auditing.

The freemium model makes it accessible to solo practitioners and small agencies, while the £149 annual license removes URL limits and adds advanced features like custom extraction and API connectivity. For most technical SEO work, especially on sites under 100,000 pages, Screaming Frog provides everything needed without the ongoing subscription costs of cloud alternatives.

FAQ

How many URLs can Screaming Frog crawl for free?

The free version crawls up to 500 URLs per project. The paid license removes this limit and adds advanced features like custom extraction and API connectivity.

Does Screaming Frog work with JavaScript websites?

Yes, it includes JavaScript rendering capabilities to crawl React, Angular, and other single-page applications. You can toggle JS rendering on/off per crawl.

Can I crawl password-protected websites?

Yes, it supports HTTP authentication, form-based login, and can maintain session cookies to crawl protected areas of websites.

How does it compare to cloud-based crawlers like Sitebulb?

Screaming Frog is desktop-based with unlimited crawls but requires local processing power. Cloud crawlers like Sitebulb offer automated scheduling and team collaboration but have usage limits.

What's the difference between SEO Spider and Log Analyzer?

SEO Spider crawls your website from the outside-in like Googlebot. Log Analyzer examines server logs to see what search engines actually crawled, helping identify crawl budget issues.
