Running Android apps in browser without installation?

Question

Google

Today I read an article on the topic: what to hope for and what to fear for a web developer.
As a result, I understood:
1) Now everyone goes to the web
2) Most of the traffic goes through mobile
3) Therefore, you need to pay more attention to the mobile version of the site
4) Big competition among studios
5) Everyone goes to ready-made platforms
and so on
But there was one point that Google allows you to virtually run applications without installation?
How can this be tested?
It seems like the latest version of chrome, there is no such button.
