Rocket.Chat, like eXo Platform, is an open source Slack alternative. This means that if your IT team wants to make it their own, go crazy.
Rocket.Chat has lots of features that Slack just doesn’t offer. This includes:
Audio and Video Conference
Built-in Live-chat for Websites
Theming and Branding
Beyond that, Rocket.Chat is incredibly intuitive. My cat could use it if she wanted.
Oh, and for the technically inclined? Rocket.Chat not only offers iOS, Android, and downloaded versions for Mac and Windows, but it’s also available for Linux.
