Piranha is a lightweight open source CMS template for building custom web applications. The Piranha framework includes, besides a powerful and flexible content model, user, group and permission management. Everything in the core framework can be extended and overridden and the manager interface is designed so that your custom views can easily be integrated to provide clients with a single user interface.
Piranha CMS is also built with publishing for several platforms in mind. Apart from of course being able to display the content through a client web-interface the core library also includes ReST API:s for other clients to connect to and retrieve content from the system.
Piranha is built using standard Microsoft tools such as MVC3, ASP.NET WebPages, WCF and Entity Framework to ensure a future proof architecture.
Piranha CMS is open source and distributed with the LGPL licence.
