Progressive web apps

Progressive web applications (PWA) are applications that are built using web platform technologies, but that provide a user experience like that of a platform-specific app.

These kinds of apps enjoy enjoy all the best parts of the Web — such as discoverability via search engines, being linkable via URLs, and working across multiple form factors, but are progressively enhanced with modern APIs (such as Service Workers and Push).

These features include being installable, working offline, and being easy to sync with and re-engage the user from the server.
