With Portofino you can create working WEB applications in minutes, just the time to describe tables, columns, relationships, all in a simple and fast web interface.
This is what we mean a real WEB Rapid Application Development Framework.
It provides a lot of functionalities out of the box like: user management and authentication, dynamic SCRUD web interface for data entry, update and search, web modeling tools, portlets, reports, workflow management.
Portofino is Open source ! And Commercial too. Dual licencing permit to choose the best business model depending on the customer needs. Open source licence is GPL with FLOSS exception, so if you need to develop for internal use or if you distribute open source software, this is the right choice. If you develop a proprietary application using Portofino and you do not want to distribute it under the terms of an open source license, you can purchase a commercial subscription.
Developers can concentrate their effort on customer needs, not on the infrastructure and avoiding repetitive-time-consuming developing activities.
The "customer pereceived value" is based on his specifications and espectations, things like user authentication, e-mail queues, data-integrity are not so evident but are necessary. With Portofino the developer can deploy a prototype application in few ours and the customer can test the prototype easily. Both are on the same "wave" and the final product will cover all the customer espectations with the right effort.
