Oily Monkey is a Chrome extension developed by 阿尔贝鲁. It falls under the category of Browsers and is specifically listed as an Add-ons & Tools subcategory. This free extension simplifies the process of injecting user scripts into target web pages.

With Oily Monkey, users can easily match the URL of the target page using regular expressions and set the script to be injected. Once the extension is activated, the script will be injected every time the target page is opened.

One of the standout features of Oily Monkey is its ability to manage multiple rule configurations. Users can set up different rules for different web pages, but only one configuration will be active at a time.
