Pay-as-you-go keyword research, rank tracking and site audits on your Cloudflare account, with an MCP server for agents
- What a Screaming Frog SEO Spider user would miss
- It has no sitemap and robots.txt tools, custom extraction or scheduled crawls; it covers near-duplicate detection and integrated crawl data only in part; the crawler runs on Cloudflare Workers, and JavaScript-rendered audits need a Workers Paid plan according to the project docs.
- What it adds
- It runs as a web app in your Cloudflare account, so audits need no desktop software, and it also covers keyword research, rank tracking, backlinks and AI visibility.
- Yes Broken links, errors, redirects. Broken links, 4xx and 5xx pages, redirect chains.
- Yes Titles, meta descriptions, headings. Missing, duplicate, long and short titles and meta, H1 checks.
- Partly Duplicate content detection. Duplicate titles, meta and identical text; no near-duplicates.
- Yes JavaScript rendering. Optional JavaScript rendering, up to 1,000 pages.
- No XML sitemaps and robots.txt testing. Reads sitemaps for discovery; no generator or robots tester.
- No Custom extraction (XPath, CSS, regex). No custom extraction found.
- Partly GA, Search Console, PageSpeed integrations. Search Console, GA4 and Lighthouse separate from crawl data.
- No Scheduled crawls, crawl comparison. No scheduled audits or crawl comparison found.
