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. ## System Designer Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource126/v4/ce/fb/17/cefb17e3-cab8-c62d-7436-6d93d35b87be/45063cdf-83db-4412-a658-0f37b8d43605_Simulator_Screenshot_-_iPhone_15_-_2024-01-28_at_18.34.02.png/2688x1242.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource126/v4/79/26/07/792607bd-90b1-d798-b692-8592ea4c1585/39c93a2a-2ecc-4206-9ce7-293a66e05836_Simulator_Screenshot_-_iPhone_15_-_2024-01-28_at_18.34.13.png/2688x1242.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource126/v4/f7/65/c0/f765c0f9-5021-1d9d-e21a-03ab185af2bd/eeb2b90a-7abc-4ef2-9ffb-7d40e994cbe6_Simulator_Screenshot_-_iPhone_15_-_2024-01-28_at_18.34.20.png/2688x1242.png) ## System Designer Rating Breakdown in United States - 5 stars: 13 (76%) - 4 stars: 2 (12%) - 3 stars: 0 (0%) - 2 stars: 0 (0%) - 1 stars: 2 (12%) ## System Designer Reviews in United States ### ***** "Awesome App" Love the app. Using it to help me plan my models for a Django app and api! Please keep innovating and working on this! -- Mrs. MasonJar, 2022-05-14 ### *---- "Glorified web app" The whole app runs only in landscape and uses quirky web-based UI. -- greensgod, 2019-04-06 ### ***** "Great work!" I honestly thought this was one of those "too good to be true" apps but boy was I wrong. Such a great app, I also highly recommend the MacOSX version. Developer you are awesome! -- Jimmy-Jamz, 2019-01-18 ### ***** "." Thank you for this great app and for sharing it for free. -- ktzkalex, 2018-12-01 ### ****- "Useful for API Design" Using this with JSON Designer to design an api. 2 stars for usefulness. 2 stars for stability (haven’t had any crashes yet). .5 stars for design, could use some polish for the ui. Feels a bit bulky as well. -- Ray96m, 2018-11-16 ### ***** "Great job" Why you make the big greating for free, I don’t know, but any way thank you.
