The Chrome app was first released in 2013. Since then, the Chrome app has made significant progress and provided a wealth of new features to the platform. The Chrome app is an app provided for Chrome, but there are multiple browsers that use Chromium, the browser engine used by Chrome, in addition to Chrome, such as Microsoft's Edge . So, the Chrome development team says that all modern web browsers will move to apps utilizing open web standard technology such as PWA .

As a result, support for the Chrome app will be phased out.

The Chrome development team has announced a schedule for the end of support for the Chrome app, and is as follows:

March 2020: Chrome Web Store stops accepting new Chrome apps. Developers can update existing Chrome apps until June 2022.
June 2020: End of Chrome app support on Windows, Mac and Linux. Users with Chrome Enterprise or Chrome Education Upgrade have access to a policy that extends support until December 2020.
December 2020: End of Chrome app support on Windows, Mac and Linux for all users.
June 2021: End of support for three APIs : NaCl , PNaCl, and PPAPI.
June 2021: End of Chrome app support on Chrome OS. Users with Chrome Enterprise or Chrome Education Upgrade have access to a policy that extends support until June 2022.
June 2022: End of Chrome app support on Chrome OS for all users.

'Fostering a robust ecosystem of extensions is critical to the Chrome development team's mission. Browse all users We will continue to provide a convenient extension platform for customizing the experience. '
