PHPixie is a newer framework introduced in 2012 with the goal of creating a high-performance framework for read-only websites. PHPixie implements the HMVC design pattern similar to FuelPHP and is built by using independent components that can be used without the framework itself. PHPixie components are 100% unit tested and just require minimum dependencies. It features standard ORM (object-relational mapping), caching, input validation, authentication and authorization capabilities. PHPixie also allows you to use the HAML markup language, enables schema migration, and has a sophisticated routing system.
