Capabilities and free crawl limit from the official SEO Spider page. Some capabilities require a paid license. Verify the current edition before purchase.
Migration or large-site investigation
If you need to inspect thousands of URLs, extract specific elements, or compare staging with production, evaluate Screaming Frog. AuditLamp's 150-page cap is an important boundary for that work.
Small-site review or client handoff
If the immediate task is to explain a site's measured issues and hand over a fix plan, try the AuditLamp scan. Judge the clarity of a real finding before paying for the details.
Differences in crawl scope, rendering, and configuration can change which issues a tool sees. Compare the URLs actually inspected, not just the headline scores. Scores from different products do not share a universal scale.
