Kolibri

Kolibri is a lightweight, flexible web application framework written in PHP 5. Kolibri’s focus is on providing you with the tools to customize the framework to your liking — from its custom URI mapper and plug-in-based core architecture, to the view technology of your choice.

Features:
- Fully Object-Oriented
- Minimal configuration
- Very lightweight and easily customizable
- Clean URIs and customizable URI to action mapper
- Flexible validation framework
- Dynamic class loading
- View technology freedom: XSL, Smarty or pure PHP
- Automated form generation (with XSL views)
- Database abstraction layer (now supports PostgreSQL and SQLite)
- No ORM (yes, it’s a feature), instead:
- SQL-to-Object Framework (SOFA)
