# Pubnub

PubNub allows us to create chat apps from scratch or add them to our applications. Pubnub enables us to focus on creating the best user experience while they take care of scalability, reliability, security, and global legislative compliance.

Using Pubnub we can create 1:1 private chats, chat rooms, group chats, or mega chats for large scale events, for a variety of use cases throughout our metaverse.
