* Build applications quickly: Many common components are included: translation tools, database access, code profiling, encryption, validation, and more. * Use specific libraries and tools: Extending existing components and adding new libraries is very easy. * Write commercial applications: Uses the BSD license, so you can use and modify it for commercial purposes. * A very fast framework: Benchmarking a framework is hard and rarely reflects the real world, but Kohana is very efficient and carefully optimized for real world usage. * Good debugging and profiling tools: Simple and effective tools help identify and solve performance issues quickly. * Know what the framework is doing: Very well commented code and a simple routing structure makes it easy to understand what is happening. * Work with objects and classes: This is an OOP framework that is extremely DRY. Everything is built using strict PHP 5 classes and objects. * Write your own code: There are no code generators and endless configuration files, so setting up is fast and easy. * Community support: A very active community forum and IRC channel means that most questions are answered very quickly.

* HTTP Router: Slim provides a fast and powerful router that maps route callbacks to specific HTTP request methods and URIs. It supports parameters and pattern matching. * Middleware: Build your application with concentric middleware to tweak the HTTP request and response objects around your Slim app. * PSR-7 Support: Slim supports any PSR-7 HTTP message implementation so you may inspect and manipulate HTTP message method, status, URI, headers, cookies, and body. * Dependency Injection: Slim supports dependency injection so you have complete control of your external tools. Use any Container-Interop container.
