History

“(...) you can write amazing Web 2.0 and Ajax apps that look exactly and behave exactly like apps on the iPhone. And these apps can integrate perfectly with iPhone services. And guess what?
There’s no SDK that you need! You’ve got everything you need if you know how to write apps using the most modern web standards to write amazing apps for the iPhone today.
So developers, we think we’ve got a very sweet story for you. You can begin building your iPhone apps today"

- Steve Jobs, Apple 2007

"It happens on the web from time to time that powerful technologies come to exist without the benefit of marketing departments or slick packaging. They linger and grow at the peripheries, becoming old-hat to a tiny group while remaining nearly invisible to everyone else. Until someone names them."

- Alex Russell, Senior Staff Software Engineer at Google

What's PWA?

A progressive web application is a website turned into an application

These apps aren’t packaged and deployed through stores, they’re just websites that took all the right vitamins… They progressively become ‘apps’.

- Alex Russell, Senior Staff Software Engineer at Google
