About Pusher
What Does Pusher Do?
Pusher is a realtime infrastructure platform that offers hosted, bi-directional APIs for building scalable realtime features in web and mobile apps. It handles complex messaging infrastructure so developers can add live updates, push notifications, and event-driven communication without managing servers.
Who Is Pusher For?
Pusher is built for software developers, engineering teams and SaaS product builders who need reliable realtime capabilities—like live chat, collaborative editing, activity feeds, or live dashboards—without building and maintaining their own WebSocket infrastructure. It’s ideal for teams using JavaScript, Node.js, Ruby, PHP, ASP.NET, Java, Python or Go. It is not designed for end-users or non-technical marketers.
Real Use Cases
Common use cases include sending programmatic push notifications to mobile devices, syncing collaborative documents in realtime, powering live chat or notification feeds, and triggering server-to-client events via pub/sub channels. Companies leverage Pusher to deliver instant updates for e-commerce order status, live sports scores, or multiplayer game actions.
