Cats and [Scalaz](https://github.com/scalaz/scalaz) have the same goal: to facilitate pure functional programming in Scala applications. However the underlying core strategy is different; Scalaz took the approach of trying to provide a single batteries-included *standard library* for FP that powers the Scala applications. Cats, on the other hand, aims to help build an [ecosystem](/cats/#ecosystem) of pure FP libraries by providing a solid and stable foundation; these libraries can have their own styles and personalities, competing with each other, while at the same time playing nice. It is through this ecosystem of FP libraries (cats included) that Scala applications can be powered with "FP awesome-ness" and beyond by picking whatever best fit their needs.

	Cats and [Scalaz](https://github.com/scalaz/scalaz) have the same goal: to facilitate pure functional programming in Scala applications. However the underlying core strategy is different; Scalaz took the approach of trying to provide a single batteries-included standard library for FP that powers the Scala applications. Cats, on the other hand, aims to help build an [ecosystem](/cats/#ecosystem) of pure FP libraries by providing a solid and stable foundation; these libraries can have their own styles and personalities, competing with each other, while at the same time playing nice. It is through this ecosystem of FP libraries (cats included) that Scala applications can be powered with "FP awesome-ness" and beyond by picking whatever best fit their needs.
