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.

Need a printable tournament bracket for a ping-pong night, a gaming tournament, a chess club or an office pool? Bracketly turns a list of names into a clean single-elimination bracket PDF in seconds — no spreadsheet, no drawing lines by hand. Type a title, paste or type your players one per line (or as a comma-separated list), choose whether to shuffle the seeds, and create. Print it, share it, or post it on the wall. • 2 TO 32 PLAYERS — any number in between. Bracketly sizes the bracket to 2, 4, 8, 16 or 32 slots and shows how many byes you'll get before you create it. • CLASSIC SEEDING — top seeds are placed apart (1 vs last, 2 vs second-to-last), and byes go to the top seeds and advance automatically to round two. • SHUFFLE OR KEEP YOUR ORDER — randomize the draw, or keep your list order as the seed order. • LABELED ROUNDS — round headers (Round of 16, Quarterfinals, Semifinals, Final) and a Champion slot at the end. • PDF AND IMAGE — a landscape US Letter PDF for printing, plus an image for group chats and screens. Honest scope: single elimination only — no double elimination, round robin or consolation brackets. The bracket is a printable sheet: you fill in the winners by hand as matches finish; scores are not tracked in the app. Everything is made on your iPhone. Nothing is uploaded, and no account is needed. Try it free — 3 brackets. A one-time $4.99 purchase unlocks unlimited brackets. No subscription, no ads. Questions: overlapmarr@gmail.com
