System Designer is a low-code development platform that allows users to easily create systems. It provides a model-driven approach, allowing developers to define their system models using UML, a widely-used standard. This means that even if you have never used System Designer before, you will already be familiar with designing in it.

One of the key features of System Designer is its use of MSON, a JSON format, to define the model. With MSON, users can define types, classes, relationships, and even multi-inheritance between classes. This provides a flexible and powerful way to create complex systems.

Once the model is defined, System Designer generates the skeletons of all the methods, making it easy for developers to add their own code to implement the desired behavior. The platform also provides helpful tools for managing components and navigating through them to create applications.

Another advantage of System Designer is its ability to create components graphically. Users can create components without writing any code, similar to creating documents in a NoSQL database. System Designer acts as an Object-Document Mapper (ODM), allowing users to manage components as NoSQL documents.

With System Designer, users can also run their systems directly from the platform. Thanks to the defined model, a dynamic type check is performed on every action of the system, ensuring that any warnings or issues are promptly identified and displayed in the interface.

Furthermore, System Designer offers the convenience of being accessible on multiple platforms, including macOS, iPad, and web browsers. It even includes a Github module that enables synchronization of work across these different apps. This allows users to seamlessly switch between devices and continue their design process wherever they are.
