Description by Erwan Carriou Written by the developer, not by AppBrain. Click to read.
System Designer is a low-code development platform for creating systems.

No matter the frameworks you use and the code you write, the most important is the model that you define to create your system.
System Designer helps you to design this model and to generate the classes and components to build your system.

DESIGN YOUR SYSTEM WITH EASE

If you look at the different JavaScript frameworks on the market, you will notice that they all have their own way to define a model, generally only with code.

System Designer uses UML, a standard, to define your model. So you probably already know how to design in System Designer even if you have never run it.

The definition of the model is stored on a JSON format called MSON. With MSON you can define types, classes, one to one / one to many relationships and multi inheritance between classes.

CODE THE BEHAVIOR OF YOUR SYSTEM

Once you have created your model, System Designer generates the skeletons of all your methods. You only have then to add your code to implement them.

System Designer provides you helpers to manage your components. You can easily navigate threw your components to create your application.

CREATE COMPONENTS GRAPHICALLY

There is no need to code to instantiate a component. Create a component in System Designer is like creating a document in a NoSQL Database.

In fact, System Designer acts as an ODM (Object-Document Mapper) to manage your components as NoSQL Documents.

RUN YOUR SYSTEM

You can run your system directly from System Designer.

Because you have defined a model for your application, a Dynamic Type Check is done on every action of your system. All warnings are send and shown in System Designer.

DESIGN ON THE GO

System Designer can be used on macOS, iPad or any browsers.

System Designer has a Github module to synchronize your work between all these apps. You can begin your design on your Mac and then continue it on your iPad.
