In their own words
SEO Crawler
SEO Crawler monitors website link health and technical SEO conditions. Its crawler checks broken links, SSL certificates, sitemap coverage, redirects, SEO signals, and orphan pages, and it can render JavaScript sites built with React, Vue, Next.js, or single-page applications. AI analysis can suggest redirect mappings and links for orphan pages, then score and prioritize issues. Paid plans support scheduled crawls, with email alerts for detected problems. Exports include CSV link data, PDF reports, and Markdown page-content files on Pro and Agency. Agency adds an API for programmatic crawls, result retrieval, domain-status monitoring, webhooks, and report exports. Crawling currently covers publicly accessible pages; login-protected areas are described as roadmap work. A crawl stops once its plan URL limit is reached and analyzes the pages collected so far. Plans are Free at free, Solo at $19 a month, Pro at $49 a month, and Agency at $149 a month. The product offers web and API access, with one domain and 100 URLs per manual crawl on Free.
