Screaming Frog is a desktop SEO crawler. crawlcrawl is a REST API for the same data.
Screaming Frog is the long-running standard for desktop SEO audits, with a visual interface SEO teams have built years of muscle memory around. It excels at one-off site audits where an analyst sits at the keyboard and reviews findings interactively.
crawlcrawl is the API alternative built for teams who run SEO audits in CI, on a schedule, or as part of a larger content pipeline. The same engine that produces a one-off audit also powers scheduled refreshes, diff-aware change detection, and webhook-driven alerting, with every feature included from $15 a month.

You automate SEO audits, run them on a schedule, or integrate them into other systems (CMS publishing, CI/CD, marketing dashboards). You audit many sites or want diff-aware change detection between runs.
You prefer a visual interface for one-off audits and your team already has the desktop workflow built around it.
