There is another extension called redirector that does the same thing. Anyone knows of the differences?
The subject of this thread seems to come preloaded with some a bunch of URLs and strings and doesn't let you create separate manipulation rules. It's literally just a "cleaner".

To Redirector's power and reflexibility: https://i.imgur.com/lYb9DtQ.png
As you can see, what Clean Links does can be done with a single Redirector rule, while having the power to create as many others as you want.
