Progressive Web Application (PWA)

A Progressive Web Application (PWA) is a type of application software delivered through the web, built using common web technologies including HTML, CSS, and JavaScript. It is intended to work on any platform that uses a standards-compliant browser, including desktop and mobile devices.

While web applications have been available for mobile devices from the start, they have generally been slower, have had fewer features, and have been less used than native apps. PWA features allow to close the gap to native applications and create similar user experiences.

PWA features include:

  • Work offline
  • Fast performance
  • Access to the phone’s sensors
  • Support for push notifications and an icon on the phone’s home screen

Since a progressive web app is a type of webpage or website known as a web application, they do not require separate bundling or distribution. In particular, there is no requirement for developers or users to install the web apps via digital distribution systems like Apple App Store or Google Play. However, for many PWA providers, the lack of visibility of the PWA in those distribution systems is a disadvantage compared to native apps. To varying degrees, the major app stores started to embrace PWAs, allowing them to be found in app stores.
