Monkey Wrench is a powerful utility available on the Chrome platform that allows users to run custom JavaScript and apply custom CSS styles on any website. With this tool, you can easily alter layouts or add additional capabilities to websites you visit regularly or someone else's site.

To use Monkey Wrench, simply right-click on the Monkey Wrench icon and click on "Options." From there, you can specify the site (URL, regular expressions supported) where you want to run your custom JavaScript and CSS. You can even add external JavaScript libraries and CSS files, allowing you to utilize CDNs and other hosted sources.

Whether you want your code to run automatically or on the click of a button, Monkey Wrench gives you the flexibility to choose. It's a user-friendly tool that empowers you to personalize your browsing experience.

Please note that Monkey Wrench is a free extension developed by Mayur Kataria. They are also planning to build a community of scripts and host them soon. If you have any scripts you'd like to share or want to contribute, you can reach out to the developer via email at
