  3. Open-Source and Free: ActiveVFP is distributed under the MIT License, making it completely free to use, modify, and distribute. This open-source nature ensures that the community has full access to the source code, which fosters transparency, collaboration, and innovation.

  4. Model-View-Controller (MVC) Architecture: ActiveVFP supports the MVC design pattern, separating the application’s logic, data, and user interface into distinct components. This separation allows for better organization of code, scalability, and easier maintenance of large web applications.

  5. RESTful API Support: In addition to web page generation, ActiveVFP can also be used to build RESTful APIs. This capability allows developers to create backend services that can communicate with other applications over HTTP, providing further versatility in building modern web solutions.

  6. Database Flexibility: While ActiveVFP is primarily designed to integrate with Visual FoxPro, it also supports other database management systems such as Microsoft SQL Server and MySQL. This flexibility makes it possible for developers to choose the best database system for their application, or even migrate from one database to another without changing the underlying framework.

  7. Free from Licensing Costs: Unlike other frameworks that may require the purchase of licenses for additional software (such as Microsoft’s Visual FoxPro), ActiveVFP is entirely free. Developers can use it to build and deploy websites without any additional financial investment, making it an attractive choice for smaller businesses or individual developers.

  8. Community-Driven Development: ActiveVFP’s development is heavily influenced by the VFP community, which ensures that the framework remains aligned with the needs of its users.
