Quix, authored by Joost de Valk, is a huge productivity enhancer for webdevelopers, and anyone wishing to have easy access to a plethora of handy tools.
Quix is am extensible bookmarklet that you simply drag into your bookmarks toolbar in Safari, Firefox and several other browsers. Then by invoking Quix, a command line opens up in a small window into which you can enter easy to remember default commands to perform a variety of functions. Since it is extensible, you can create your own custom commands as well.
For instance, say you want to quickly check what your ip address is… you would invoke Quix, type in “myip” in the command line and hit enter and you’ve instantly got your ip displayed in your browser window. Another example is if you want to measure the size of an element on a webpage, you’d invoke Quix, type in “ruler” and a cross-hair appears on your screen with a dimensions palette next to it and you can easily measure a graphic or any area on the current webpage you are on.
I haven’t counted all the functions available in Quix but there are surely over 60 of them and most are easy to remember… “ruler” for the aforementioned ruler tool, “gs” for Google search, “a” for Amazon search, “bitly” for bit.ly URL shortening, you get the idea. The complete list is located on the Quixapp website
It’s a real time-saver and obviates the need to have lots of add-ons since so many functions are taken care of by Quix. Joost admits that the inspiration for Quix came from another similar app called Shortwave which was created by Shaun Inman.
