Systems and methods for application development via a graphical user interface (GUI) using an Entity-Component-System (ECS) architecture are provided herein. In some embodiments, a method for application development may include receiving a selection of at least one actor to be part of a game scene; displaying a representation of the at least one actor in the game scene; receiving a selection of one or more behaviors to associate with each of the at least one actors in the game scene; storing the selected one or more behaviors as associations with each of the at least one actors, wherein the associations are stored in a hash table; updating, each of that at least one actors and their associated behaviors; and automatically creating an executable video game based on the at least one actor and associated behaviors in an ECS architecture without the need for user written software code.
