PlayMaker is a very popular visual scripting tool (based on finite-state machine, FSM for short), also a hierarchical logic framework for Unity, developed by Hutong Games from China. Game designers and programmers can use PlayMaker to conduct interactive development with Unity, and quickly complete prototyping of games. Therefore, it is suitable for both independent developers and team collaboration, greatly improving the game development efficiency.

If you want to create your own desktop or mobile applications (such as HTML5 apps, WebApps, Progressive WebApps, WebExtensions and Hybrid apps), whereas you do not even have any or at least enough programming skills, then you must ask help for some foolproof visual designers to do this. DecSoft App Builder (formerly called App Builder) is such kind of a complete and straightforward visual development environment for Windows.
