When each tool wins

Pick Screaming Frog when…

You need to crawl an entire site (10k+ pages) and explore link graphs, redirect chains, and broken pages interactively.
You like working in a desktop UI with filters and exports.
You audit sites manually a few times a quarter, not continuously.

Pick SEO Score API when…

You want audits to run automatically — in CI, on a schedule, or from an AI agent.
You audit many sites or many specific URLs without doing a full crawl.
You want a JSON response your code can act on, not a desktop spreadsheet to interpret.

Frequently asked

Can SEO Score API crawl an entire site like Screaming Frog?

Not in one call. SEO Score API audits a single URL per call (or many in a batch). For full-site crawls of 10k+ pages, Screaming Frog is the better tool. Many teams use both: Frog for periodic deep crawls, SEO Score API for automated per-URL checks in CI.

Does SEO Score API run in CI/CD?

Yes — we publish a GitHub Action and Python/Node SDKs. Screaming Frog has a CLI mode but it requires installing the desktop app on your runner.

Why is SEO Score API cheaper?

We run a focused product (on-demand audits via API) and don't pay for desktop UI, support staff for non-developers, or bundled features. Different scope, different price.

Can I get JSON output from Screaming Frog?

Frog exports CSV/Excel and has scheduled exports, but it isn't an API. You can't `curl` it. SEO Score API is JSON-first.
