Azure Web PubSub

Real-time messaging for web applications using WebSockets and the publish-subscribe pattern.

Build real-time messaging into your web applications

Develop web applications with real-time messaging using Azure Web PubSub, a fully managed service that supports native and serverless WebSockets. Create loosely coupled, scalable applications—including chats, live broadcasting, and IoT dashboards—with the publish-subscribe messaging pattern. Keep your focus on functionality while Web PubSub manages the flow of data and content to your webpages and mobile applications.

Real-time publish-subscribe messaging for web application development through native and serverless WebSocket support
