Unlike other frameworks that require you to spend an hour or so to read the users' manual, waste your time on a truck load of configuration options just to display your first "Hello, World" in your browser, mislead you into believing "fast is everything", and force you to follow a strict set of difficult-to-navigate directory structures and obtrusive programming steps, Fat-Free gives you a lot of freedom - and style - to get the work done with ease and in less time.
Having Fat-Free as part of your toolkit does not mean your code will be governed by it. Although your programming habits may change a bit because of the elegant design patterns and compact command set available, you control which features you need. You can accomplish a lot even if you use just a subset of what's available.

Has a pretty neat way of doing routing and the core library is just 60kb!
