See how CRFT Lookup compares to Octopus.do in features and capabilities. Both tools visualize sitemaps, but we go beyond with performance analysis, technology detection and meta tag previews.

Scan a website
While both tools help visualize website structure, they serve different purposes. Octopus.do crawls websites to discover pages and allows collaborative sitemap planning. CRFT Lookup, on the other hand, visualizes existing sitemap.xml files and provides additional insights like technology detection, performance metrics, and SEO analysis. Since most modern frameworks and website builders auto-generate sitemap.xml files today, the Lookup offers a quick way to visualize and analyze existing sites without the limitations of web crawling.
Use Octopus.do when you're planning a new website's structure or need collaborative sitemap editing features. Use CRFT Lookup when you want to analyze an existing website that already has a sitemap.xml file (most do!) and want insights into its technology stack, performance metrics, and SEO optimization.
Very accurate, since we read directly from your sitemap.xml file rather than crawling your site. While Octopus.do's crawler can discover pages not in your sitemap, it often has rate limits and depth restrictions to manage costs. Most modern websites auto-generate comprehensive sitemap.xml files, making direct sitemap parsing both faster and more reliable for existing sites.
No, CRFT Lookup is an analysis tool, not a sitemap editor. If you need to create, plan, or collaboratively edit a sitemap, Octopus.do is better suited for that purpose. CRFT Lookup focuses on visualizing existing sitemaps and providing technical insights about live websites.
Yes, CRFT Lookup is completely free to use with unlimited scans. You can access all features including sitemap visualization, technology detection, performance analysis, and SEO insights without any cost. While Octopus.do offers different pricing tiers for their collaborative sitemap planning features, we keep our analysis tool free and monetize through our web development services instead.
