What it is

Greenflare is a free, open-source SEO web crawler for Linux, macOS and Windows. It reports page elements such as titles, meta robots directives and canonical tags, and analyzes HTTP headers and response codes including 301, 404 and 503. It parses robots.txt and can identify broken internal links returning 3xx, 4xx or 5xx responses. Users can extract information with XPath or CSS selectors and exclude URLs with patterns. Crawl results can be filtered and sorted, and any view can be exported to CSV. The project says Greenflare has been tested on sites with more than four million URLs. Its databases use SQLite tables and the .gflaredb extension. Installation options described by the project include pre-built installers and a Python package installable with pip. Bug reports go through GitHub issues, and developers can contribute pull requests. However, the official homepage says it has no published content, the listed download URL returns a 404 error, and the features and integrations pages are inaccessible. The official about page displays unrelated content.
