* 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.

• Concise: Silex exposes an intuitive and concise API that is fun to use. • Extensible: Silex has an extension system based around the Pimple micro service-container that makes it even easier to tie in third party libraries. • Testable: Silex uses Symfony2's HttpKernel which abstracts request and response. This makes it very easy to test apps and the framework itself. It also respects the HTTP specification and encourages its proper use.
