Implementations generally relate to a method of automatically generating applications for multiple platforms based on one source of application code. Implementations include receiving a signal from a client device to initiate an application generation process, for example, through a graphical user interface (GUI). In an implementation, the application generation process analyzes the application code to differentiate between core application code, which is shared between many platforms, and device-specific code, and then separates the core application code from the device-specific code. The core application code may then be deployed for use in a plurality of applications such as a web application, progressive web application, or, as taken together with device-specific code, as a native mobile application. Applications may be deployed with features that are automatically determined based on their deployment method and the feature set of each platform.
