Everybody should check on the health of websites regularly, and a lot can be done with free tools. Here is the list of the tools I use for my website and the websites of my clients. Most of the tools on the list don’t require you to register before you can use them, so that’s always a big plus.

  • Google Chrome Dev Tools

Chrome browser has some excellent development tools. The console will help you track down errors in scripts. But the new lighthouse tool will let you know about improvements for every aspect of your site. The performance section tests various devices and network conditions for real-world scenarios.

To find Lighthouse, open dev tools in chrome (from “View/Develop/Developer Tools”  and select “audits” and then “Perform an audit”.
