Beam Us Up vs Checkbot

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.

Checkbot is a Chrome extension for auditing websites for SEO, speed, and security issues. Its checks can flag broken links, duplicate content, invalid HTML, and insecure forms. The crawler can examine hundreds of pages in minutes, while site structure information shows linked pages, image, JavaScript and CSS files, non-indexable pages, and redirects. It can also reach staging and local development sites, password-protected pages, and private networks. Crawling and other functions run locally on the user's machine; Checkbot says it does not operate as a web service. The free Basic plan allows 100 URLs per crawl, unlimited crawls and sites, with ads. Professional costs $10 a year, billed $120 per year, or $15 a month; it raises the crawl limit to 10,000 URLs and adds localhost crawling, PDF reports, CSV and bulk export, and HTTP Auth support. The extension runs on Windows, macOS, Chrome OS, and Linux, but does not execute JavaScript during crawls. Usage analytics and crash reports are opt-in.
