Greenflare review
A focused free crawler for core on-page checks, with limited platform depth.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Greenflare is a lightweight, free, open-source SEO web crawler for Linux, macOS, and Windows. It is designed for people who need focused on-page checks rather than a broader SEO visibility platform. The crawler reports on-page SEO elements, HTTP headers, HTTP status codes, robots.txt rules, broken internal links, and crawl data. Its open-source model also makes it a practical option for users who prefer a freely available tool with a narrow technical focus.
The feature set covers useful crawl customization and review workflows. Custom XPath and CSS extraction can extend reporting beyond the built-in fields, while custom URL exclusion rules help control which pages are crawled. Crawl data can be filtered and sorted, then exported to CSV for further handling. Greenflare also supports SQLite-based crawl databases, and the project repository describes installers and a Python package. These capabilities make it suitable for focused audits where on-page details, crawl findings, and exportable results matter most.
Greenflare is less suitable for teams seeking an ongoing, connected SEO workflow. It lacks verified JavaScript rendering, scheduling, integrations, and broader visibility features, so it should not be the first choice for projects that depend on those capabilities. Choose it for free, open-source crawling across Windows, macOS, and Linux, especially when core technical checks are the priority. Choose an alternative when scheduled monitoring, integrated workflows, JavaScript-heavy analysis, or wider search visibility reporting is central to the requirement.
