Google Hangouts. Google Hangouts is a communication platform developed by Google which includes instant messaging, video chat, SMS and VOIP features. It replaces three messaging products that Google had implemented concurrently within its services, including Google Talk, Google+ Messenger (formerly: Huddle), and Hangouts, a video chat system present within Google+.
Also, its integration with several other Google services (such as Gmail, Google Chrome, and Google Voice) can make it somewhat cumbersome to use, unless you use a lot of products from Google anyway. However, if you're looking for alternatives to Google Hangouts that are more user-friendly and not so heavily tied into a network of other services, try one of these six apps like Google Hangouts. 1. Skype. A very popular Google Hangouts alternative, Skype is currently run by Googleâs rival Microsoft. You can use it as a stand-alone service, or connect it with your Microsoft account. Like with Google Hangouts, you can use Skype to exchange text messages, pictures, and computer files with anyone else whom you have added as a Skype contact (or who has added you as one). You can also chat with them over a live video feed!
