SEO Tools

Screaming Frog SEO Spider is a desktop-installed technical SEO crawler used to audit on-site issues at scale - broken links, duplicate content, missing metadata, and JavaScript rendering.

ABOUT SCREAMING FROG SEO SPIDER

Screaming Frog SEO Spider is a desktop-installed crawler - not a cloud SaaS - and remains the technical-SEO reference tool for auditing sites at scale. The free tier is capped at 500 URLs per crawl; a paid licence lifts the cap and unlocks scheduled crawls, JavaScript rendering, and structured-data extraction.

OVERVIEW

Who is it for?
SEO consultants, agencies, and in-house technical SEO teams that need to audit large sites on their own machine.
Problem
Broken links, redirect chains, duplicate content, missing metadata, and JavaScript rendering issues on large sites are hard to surface without a full configurable crawl. Cloud crawlers often cap URLs low on the free tier and hide raw crawl configuration.
Solution
A desktop crawler for Windows, macOS, and Linux that walks a site at configurable depth, flags response codes, redirects, metadata, and structured data, and renders JavaScript for SPA and dynamic sites. Integrates with Google Analytics, Search Console, and PageSpeed Insights.
What makes it unique
Runs locally rather than as SaaS, so crawl scope and configuration are fully under the operator's control. A single annual licence (199 GBP) unlocks unlimited URLs, custom extraction via CSS Path, XPath, or regex, scheduled crawls, and crawl-to-crawl comparison.
