Various embodiments enable a web browser to promote the availability of an installable application that is associated with a website to which the web browser has been navigated. The web browser is configured to discover the availability of these applications and, responsively, provide a user experience through which the user can acquire and install such applications, as well as switch to applications that have previously been installed. Thus, through the various embodiments, a user is relieved of the burden of having to navigate to a particular application store and periodically search for applications associated with sites to which they browse.
