Check My Links Chrome browser extension is a link checker that crawls through your webpage and looks for broken links.

It is developed primarily for web designers, developers and content editors. When you’re editing a web page that has lots of links, wouldn’t it be handy to be able to quickly check that all the links on the page are working ok? That’s where ‘Check My Links’ comes in. ‘Check My Links’ quickly finds all the links on a web page, and checks each one for you. It highlights which ones are valid and which ones are broken, simple as that.

You can copy all bad links to your clipboard with one click! HTTP response codes and full URLs of broken links are published in the Console log (Found in: ‘Chrome > Tools > Javascript Console’ or Ctrl+Shift+J).
