Why PubNub?

Our standard messaging features allow you to build direct, group, and large scale chat without needing to maintain the infrastructure and backend yourself.


Why use PubNub for chat?

Go to market quickly with Chat Components

Pre-built chat components let you create engaging apps in minimal time, without sacrificing customization.

Flexible client SDKs

PubNub Chat SDKs are built on top of a globally distributed Data Stream Network with 15+ points of presence across the globe with response times of <100ms and 99.999% uptime guarantees.

Programmability with Functions

Extend your chat by building additional functionality with PubNub Functions, such as translation, chatbots, profanity filtering, sentiment analysis, and more.

Enterprise grade security and compliance

Operate securely through TLS and AES256 encryption, and access flexible authorization schema through OAuth and LDAP models. We require no inbound open ports, which helps prevent attacks on your infrastructure. Plus, we support compliance for regulatory environments that include HIPAA, GDPR, SOC2 Type 2, and CCPA.


A platform solution for all your real-time needs

As a real time communication platform, we allow you to build additional in-app experiences out-of-box chat APIs can’t provide, like push notifications, geolocation tracking, data streaming, collaboration and more.
