Giotto is a framework based on the model, view and controllers (MVC) concept. Some of the characteristics of Giotto include a free RESTful interface, automatic URL routing, and Jinja2 for HTML templates with an API. This framework promotes functionality while the code for model, view, and controller is separated from an existing association.
Late last year, ProgrammableWeb reported that Zend, the PHP company, launched a new open source project named Apigility. This project makes it possible to quickly and easily create high-quality APIs that reflect industry best practices and standards. Zend has now announced a new version of Apigility which includes new features and improvements allowing users to create APIs with RPC and REST services, authentication, documentation, and much more.
