Abstract: A computing device, including one or more output devices and a processor. The processor may be configured to download a web application. The web application may include an authorization certificate and a metadata file that includes an identifier of at least one local application program interface (API) of the computing device that is not included in an API whitelist of a web host application program. The processor may determine, based on the authorization certificate and the metadata file, that the web application is authorized to access the at least one local API. The processor may execute the web application at the web host application program. Executing the web application may include utilizing the at least one local API. The processor may convey at least one output of the web application for output at the one or more output devices.

Abstract: According to one set of embodiments, a computer system can expose, to a non-native software program running in a web browser of the computer system, one or more native OS APIs implemented by an OS of the computer system, where the exposing enables the non-native software program to invoke the one or more native OS APIs as part of its execution within a runtime environment provided by the web browser.

Abstract: A computer device is provided that includes a processor configured to execute a first application configured for a first user interface framework, instantiate a host window of the first application using the first user interface framework, and execute a second application, that is out of process with the first application. The second application is configured for a second user interface framework that is incompatible with the first user interface framework. The processor is further configured to instantiate a hosted window of the second application using the second user interface framework, establish a cross-process interface between the first application and the second application configured to exchange rendering information between the hosted window and the host window, and cause the host window to display the rendering information from the hosted window within the host window on a display of the computer device.
