Google just announced Hangouts as a standalone Chrome app. “Today, we’re introducing the Hangouts Chrome App for Chrome OS and Windows — a simpler, faster way to use Hangouts on your computer alongside whatever else you’re doing,” writes David Levin, Software Engineer at Google.
Though Google didn’t bother to mention Linux, if you are running Chrome browser you can easily install the app from the Chrome Store. The app will be added to the Chrome Apps and you can easily access it from your Linux desktop.
