Our verdict on CrawlZilla
CrawlZilla is a browser-based technical SEO crawler for SEO professionals, agencies, developers, and businesses auditing websites at scale. It crawls HTML, images, JavaScript, CSS, and PDFs, reporting on more than 40 SEO data points per URL. Its scope covers titles, canonicals, hreflang, structured data, Open Graph data, internal links, orphan pages, Lighthouse performance, and Core Web Vitals. It is best suited to teams working across large websites that need high crawl capacity and scheduled monitoring.
The plan structure is built around crawl volume and request speed. Free supports 10,000 URLs per crawl and 10 requests per second. Premium costs £39.99 per month and raises capacity to 1,000,000 URLs per crawl with 20 requests per second. Ultimate costs £79.99 per month and supports 10,000,000 URLs per crawl with 50 requests per second. Enterprise supports 100M+ URLs per crawl and includes dedicated infrastructure. The free plan gives smaller audits an accessible starting point, while paid tiers target larger websites and higher-volume crawling.
CrawlZilla’s standout strength is the breadth of its technical audit within a high-capacity crawler. Headless Chrome enables JavaScript rendering, while Lighthouse and Core Web Vitals audits add performance analysis. Scheduled page monitoring, SEO change alerts, CSV and spreadsheet exports, hreflang checks, structured-data analysis, internal-link graphs, and orphan-page analysis extend its use beyond one-off crawls. Integrations are absent, and the product is web-only, so teams needing connected workflows or a broader platform ecosystem should consider an alternative. Choose CrawlZilla for large-scale technical SEO analysis; choose another tool when integrations are central to the workflow.
