'''User scripts''', or '''userscripts''', are scripts that make on-the-fly changes to specific web pages on the client side (in the browser or a proxy server), typically to change their appearance or to add or modify functionality.

User scripts for [[Greasemonkey]] and Greasemonkey-compatible alternatives are written in [http://developer.mozilla.org/en/docs/JavaScript JavaScript], but there is at least one example of using another scripting language, namely Ruby in [http://github.com/why/mousehole/tree/master/ MouseHole].

For tools other than Greasemonkey that apply user scripts to web sites, see [[Cross-browser_userscripting|Cross-browser Userscripting]] and [http://en.wikipedia.org/wiki/Greasemonkey#Compatibility Wikipedia].
