SiteOne Crawler

This free, multi-platform desktop application (with a command-line interface available) offers in-depth website analysis (security, performance, SEO, accessibility). The goal is to provide a comprehensive analysis of all relevant areas using a single tool and help uncover issues that aren't immediately visible at first glance. The primary output is a well-structured HTML report, which can be easily shared with colleagues. You can effortlessly upload the output report to our cloud, with the report's lifespan adjustable from as short as one hour to indefinitely. Text and JSON outputs are also available for further processing. Designed for ease of use, the tool features a simple installation process and a user-friendly interface. A particularly valuable feature is the ability to export an entire website for offline use, allowing it to run from a local disk without needing a web server—complete with styles, fonts, images, and documents. The tool's creator aims to develop a free solution that assists developers, testers, and website owners in improving the quality of websites worldwide. Therefore, we welcome your feedback, suggestions, and ideas for potential enhancements. Thank you!
