Google on Wednesday announcd that it will begin to phase out traditional Chrome apps starting in June, and winding down slowly over two years’ time.

Google will begin phasing out support for Chrome Apps across all operating systems as follows:

• March 2020: Chrome Web Store will stop accepting new Chrome Apps. Developers will be able to update existing Chrome Apps through June 2022.
• June 2020: End support for Chrome Apps on Windows, Mac, and Linux. Customers who have Chrome Enterprise and Chrome Education Upgrade will have access to a policy to extend support through December 2020.
• December 2020: End support for Chrome Apps on Windows, Mac, and Linux.
• June 2021: End support for NaCl, PNaCl, and PPAPI APIs.
• June 2021: End support for Chrome Apps on Chrome OS. Customers who have Chrome Enterprise and Chrome Education Upgrade will have access to a policy to extend support through June 2022.
• June 2022: End support for Chrome Apps on Chrome OS for all customers.

This change does not impact support for Chrome Extensions. Google will continue to support and invest in Chrome Extensions on all existing platforms.

Google had initiallysaid four years ago that it would phase out Chrome apps on Windows, Mac, and Linux in 2018.

According to Google, Chrome apps will be replaced by rich web apps, which will essentially replicate the function of a Chrome app inside of a webpage. Google has a developer-focused transition page where the company encourages developers to build Progressive Web Apps, or a combination of an extension and a web app, so that the extension can load the web app’s UI from an external page.
