What Greenflare is

Greenflare is a free, open-source SEO web crawler for Linux, macOS, and Windows. It reports on page elements such as titles, meta robots, and canonical tags, and analyzes HTTP headers and status codes including 301, 404, and 503. It parses robots.txt and can flag broken internal links returning 3xx, 4xx, or 5xx responses. For more targeted reviews, users can extract information with XPath or CSS selectors and exclude URLs using patterns. Crawl results can be filtered and sorted, and any view can be exported to CSV. Greenflare stores its databases as SQLite tables using the .gflaredb extension. The project says the crawler has been tested against sites with 4M+ URLs and describes pre-built installers as well as a Python package installable with pip. Bug reports go through GitHub issues, and developers can contribute pull requests. However, the official homepage says no content has been published yet, the listed download URL returns a 404 error, and the features and integrations pages were inaccessible. The official about page currently shows unrelated gambling content.
