Screaming Frog is a UK-based SEO software company and search marketing agency, best known for the SEO Spider website crawler tool used by SEO professionals worldwide to perform technical SEO audits, crawl analysis, and integrations with third-party APIs. The SEO Spider integrates with Google Analytics (GA4), Google Search Console, PageSpeed Insights, Ahrefs, Majestic, Moz, OpenAI, Gemini, Ollama, and Anthropic. Screaming Frog also offers a free Log File Analyser for analyzing server log files to understand search bot behavior. Screaming Frog operates no public web API. Its machine-callable surfaces are the SEO Spider command line interface, which runs the product fully headless, and — since version 24.0, released 19 May 2026 — a first-party Model Context Protocol server built into the desktop application, exposing 29 tools for crawl control, reports, bulk exports, URL inspection, screenshots, embeddings, Node scripting and sandboxed file access. The MCP server is a paid licence feature and runs inside the user's own installation over stdio or a loopback HTTP transport; there is no hosted endpoint.
Screaming Frog publishes 2 APIs on the APIs.io network. Tagged areas include SEO, Website Crawler, Technical Audit, Marketing, and Analytics.
The Screaming Frog catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Screaming Frog’s developer surface includes engineering blog, pricing, support, changelog, and 15 more developer resources.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
