Messenger for Desktop is an unofficial client that allows you to use Facebook’s messaging service on your PC without having to be connected to the social network.
It has exactly the same options as the Facebook Messenger mobile apps: chat, stickers, and voice and video calling.
If you regularly use the chat option on the Facebook website, you’ll have no trouble using Messenger for Desktop.
Messenger for Desktop is a perfect software for anyone who wants to have persistent access to Facebook chat without having the need to keep Facebook loaded in their browser.
In terms of design, Messenger for Desktop has a very similar interface to Facebook.
