Screaming Frog

Screaming Frog SEO Spider is the de facto standard for technical site crawling. Every SEO specialist uses it: it analyzes thousands of URLs in minutes, finding broken links, redirects, meta tag issues, duplicate content and much more that cloud tools can't replicate.

Screaming Frog SEO Spider is SEO crawling software for Windows, macOS and Linux that simulates the behavior of a search engine by scanning a site URL by URL. It installs locally and analyzes the site from your own machine, making it much faster and deeper than cloud crawlers for sites with many pages. The analysis covers a vast range of technical aspects: internal and external links, images, HTTP response codes, redirect chains, title and description meta tags, H1 and H2 tags, canonical tags, hreflang, duplicate content, sitemaps, structured data, JavaScript rendering. Results are shown in filterable, CSV-exportable tables. It integrates with Google Analytics, Google Search Console and PageSpeed Insights to enrich data with performance metrics. The free version limits crawling to 500 URLs, sufficient for small sites and testing the tool; the annual license removes this limit. Screaming Frog is the first tool almost every SEO specialist installs when starting work on a new site.

For SEO specialists, agencies and web developers who need in-depth technical analysis of websites of any size, with maximum control and scan speed.

Screaming Frog SEO Spider has a free version limited to 500 URLs per crawl. The annual license costs £259 (around $330 at the current exchange rate) per user and removes all URL limits, also unlocking advanced features such as JavaScript crawling, custom configurations and integrations with major tools. There are no monthly plans: the license is annual. It's one of the best value-for-money professional SEO tools.
