Technical SEO crawler with optional AI integrations
Screaming Frog SEO Spider
Screaming Frog SEO Spider is a desktop website crawler for technical SEO audits. It collects crawl data that specialists can use to investigate site structure, links, response codes, metadata, indexability, and XML sitemaps. Optional AI integrations can analyze crawl data, but the product is primarily a crawler—not an AI content-writing platform.
Crawl and diagnose technical issues
SEO Spider crawls a site and reports issues such as broken links and server errors, redirects, page titles and metadata, indexability signals, and XML sitemap URLs. The configurable crawler helps technical SEOs and developers inspect a site, validate changes, and export findings for investigation. Crawl settings and interpretation matter: a reported issue needs context before it becomes a change to the site.
It is a practical choice for hands-on technical audits, migrations, and crawl QA. It is not a turnkey content planner or keyword research suite; compare Semrush for search research and tracking, or Surfer SEO for content optimization workflows.
AI is optional analysis, with separate setup
SEO Spider can connect to external AI model APIs, including OpenAI, Gemini, and Anthropic, or local model software such as Ollama. Users can configure preset or custom prompts against crawl data and page content for tasks such as classification, extraction, or semantic analysis. AI does not replace the crawl or a technical SEO review, and generated output should be checked before use.
The official feature comparison lists crawling with OpenAI and Gemini among paid-version capabilities. Using external providers requires setting up an account and API credentials, and provider charges or rate limits may apply separately from the SEO Spider licence. Local model setups differ and may not require an API key. Consider what page data is sent to a provider and configure prompts and data handling accordingly.
Licence and operational considerations
The free version allows up to 500 URLs per crawl. The annual paid licence removes that URL cap subject to available system resources and unlocks advanced features; check the official pricing and feature comparison for current licence terms. Larger or JavaScript-heavy sites may need crawl configuration and enough memory, while teams new to technical audits should expect to learn how filters and crawl settings map to their site.
