What it is

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.
