The problem
Site audits are table stakes for every SEO tool and agency — and a crawler is the least differentiated, most painful thing you can build.
Queues, politeness rules, JS rendering, retries, storage — months of engineering that your users will never see or thank you for.
→ One task_post call starts the crawl. We run the machines.
Screaming Frog on a laptop doesn’t scale to 50 clients or plug into your product. Exports and re-imports eat entire days.
→ Everything arrives as JSON, straight into your pipeline.
What Google renders and what your basic crawler sees can be very different pages.
→ JS rendering and full browser mode, priced per page.

}What's inside
One API covers the whole technical SEO surface — pick the mode that fits the job.
Crawl entire domains with 60+ checks per page: meta, status codes, internal links, duplicates, non-indexable pages, and an overall OnPage score.
See pages the way Google does — JavaScript rendering from $0.0015 per page, full browser rendering with Core Web Vitals from $0.0051.
Google Lighthouse audits and page-timing metrics through the same API — performance data next to your SEO data.
Audit any single URL in seconds, or parse a page’s content structure — both at $0.00015 per page.
