The software is available for Windows and macOS. Free mode permits 500 page URLs and 500 imported URLs per website. Professional is listed at $49 a month, with no fixed crawl limit and command-line support. The maker lists a fully functional 30-day evaluation period and a 30-day satisfaction guarantee.
