Simblog aims to be one of the most easy-to-use and lightweight blogging platforms. It emphasizes user experience, workflow, and ease of use without neglecting usability and extensibility. It will take full advantage of what HTML5 and CSS3 have to offer without delving too deeply into experimental features. It is built on its own lightweight framework, which allows a high degree of extensibility and modularity for your blog. It uses Smarty as a templating engine (which also provides a caching mechanism), jQuery and Kendo UI for frontend design, and MySQL as a database.
PWF (PHP Web Framework) is an extremely lightweight but powerful PHP Web framework that uses the MVC pattern and object oriented programming. It makes it easier to write applications with clean code and clear architecture, and has a small learning curve. It doesn’t need installation and works in most environments. The controller used for each request is selected through simple but effective rules, and the method by the type of the request. It provides database abstraction with data-object mapping.
