HMVC is a collection of traditional MVC triads operating as one application. Each triad is completely independent and can execute without the presence of any other. All requests made to triads must use the controller interface, never loading models or libraries outside of their own domain. FuelPHP is released as a free and open source framework under the MIT License and can be used for commercial and personal projects alike.
