What Greenflare is
Greenflare is a free, open-source SEO crawler for Linux, macOS, and Windows. It reports on page elements such as titles, meta robots, and canonical tags, analyzes HTTP headers and status codes, and parses robots.txt. It can also identify broken internal links with 3xx, 4xx, and 5xx responses. For more targeted checks, users can extract information with XPath or CSS selectors and exclude URLs using patterns.
Crawl data can be filtered and sorted, and any view can be exported to CSV. Greenflare stores database data in SQLite tables using the .gflaredb extension. The project says it has been tested on sites with more than four million URLs. Installation options described by the project include pre-built installers and a Python package installed with pip. Bug reports go to GitHub issues, and developers are invited to submit pull requests. Access to product information is limited: the homepage says it has no published content, the download URL returns a 404 error, and the features and integrations pages are inaccessible.
