Progressive Web Apps (PWAs) are applications that you build by using web technologies, and that can be installed and can run on all devices, from one codebase.
PWAs provide native-like experiences to your users on supporting devices. They adapt to the capabilities supported by each device and they can also run in web browsers, like websites.
