Techniques for modes for applications are described. In one or more implementations, multiple operational modes are provided for an application. The operational modes can be associated with different resource access permissions, trust statuses, graphical user interfaces, and so on. An application can be launched in a particular one of the operational modes based on a context in which a request to launch the application is received. In one or more implementations, correlations between launch request contexts for an application and operational modes can be configured to enable different launch requests to cause an application to launch into different operational modes.
