Pusher SDK

Pusher SDK is the leading real-time messaging infrastructure trusted by over 300,000 developers and companies including GitLab, Intercom, and thousands of applications requiring instant data synchronization. As the pioneer of managed WebSocket services, it has become the standard for adding real-time features to web and mobile applications without the complexity of building custom infrastructure.

What makes Pusher SDK exceptional is its managed approach to real-time communication that eliminates the need to build and maintain WebSocket infrastructure while providing enterprise-grade reliability and global scale. This developer-first design enables teams to add live features in minutes rather than months.

Developers and product teams choose Pusher SDK because it provides production-ready real-time capabilities without the operational overhead of managing WebSocket servers, connection handling, or scaling challenges. From chat applications to live dashboards, it offers the reliable real-time foundation that modern user experiences demand.
