Beam Us Up vs Website Grader

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.
