A userscript manager is a type of browser extension and augmented browsing technology that provides a user interface to manage scripts. The main purpose of a userscript manager is to execute scripts on webpages as they are loaded. The most common operations performed by a userscript manager include downloading, creating, installing, organizing, deleting and editing scripts, as well as modifying script permissions (e.g. website exceptions).
One aspect of userscripts is that they can be shared. They can be uploaded to a userscript repository where they become available to other users for downloading. Some examples of userscript repositories include Greasy Fork, OpenUserJS, and Userscripts.org.
