Pusher is a hosted realtime communication platform that makes it easy for developers to add live features — like realtime updates, chat, notifications and activity feeds — to their web and mobile applications through simple APIs. As one of the earlier and most established players in realtime infrastructure, Pusher abstracts away the complexity of websockets and persistent connections, letting developers implement realtime functionality quickly without having to build and scale the underlying messaging systems themselves.

The platform's core product (Channels) provides pub/sub messaging over websockets, so you can broadcast events from your server to many connected clients in real time — powering features like live dashboards, collaborative apps, realtime chat, live scores and instant notifications. It also offers push notification capabilities for sending native notifications to mobile and web devices. With clean APIs and SDKs across many languages and platforms, Pusher lets developers add these live experiences with relatively little code, handling the connection management, scaling and delivery behind the scenes so the features just work.

Pusher is used by developers and companies that want to add realtime features to their applications quickly and reliably without operating their own realtime infrastructure. By providing well-documented, easy-to-use hosted APIs for realtime messaging and notifications, it lowers the barrier to building live, engaging experiences and lets teams focus on their application rather than the plumbing. Its longevity and broad adoption have made it a familiar, trusted choice in the realtime space. As users increasingly expect instant, live updates and interactive features, and as developers look to add them without heavy infrastructure work, hosted realtime APIs remain valuable. For developers who want a simple, reliable way to add realtime updates, chat and push notifications to their apps, Pusher offers a capable, well-established and developer-friendly solution.
