There are several options that can be used to access Google Hangouts: from Gmail, G +, or Chrome extension. But it seems that Google feels
the need to provide an independent web page for Google Hangouts so that users
can access the service directly from the browser.
This consideration finally encourages Google to create
hangouts.google.com. Through this independent site, users who don't want to
install extension, or want to get a different experience can be connected to
friends and relatives through the browser.
Google Hangouts site is created in a simple display. You
won't see a lot of images or other accessories which will give complicated
impression. When you visit the site, you will be greeted by three communication
buttons: message, phone call and video call.
Google also provides similar features for mobile users,
either for Android or iOS. In addition, users can also create conversation
group which consists up to 100 people. Inside this group users can share
pictures and text messages that are decorated with emoji, stickers and gif.
The group call feature can also be accessed via browser.
This tool can be enjoyed by 10 people in a single chat.
Google Hangouts display will change after you login to your
account. On the left side you will see a panel that contains your contact list.
The content of this panel will adjust according to the three main functions
provided. If you're still curious, you can visit hangouts.google.com.
