Beam Us Up vs Greenflare

Beam Us Up is a downloadable SEO spider crawler that runs on a computer. The maker describes it as completely free with no limits. It checks links, redirects, duplicate content, headings, metadata, sitemaps, crawl depth, blocked URLs and Google PageSpeed. Version 2.0 reports whether robots.txt permits or blocks 27 search engines and AI bots, and can render JavaScript pages through Chrome or Edge installed on the computer. Two crawls can be compared to identify fixed, new and remaining problems and page changes, with comparison data exported as CSV files in a ZIP. The maker says version 2.0 can crawl sites with 100,000 or more pages. Command-line mode writes a JSON report and returns an error code when selected problems appear. Optional checks cover security headers and SSL certificates. MCP connections to listed AI assistants are supported. Browser passwords remain in memory only while the app is open.

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.
