Core Feature

Pub/Sub Channels

Channel Patterns

Use wildcard patterns and namespaces like chat:room-* to organize your messaging topology. Subscribe to entire groups of channels with a single call.

Message Filtering

Filter messages server-side by metadata, type, or content fields so clients receive only the data they need — reducing bandwidth and processing.

Guaranteed Delivery

At-least-once delivery ensures every published message reaches every active subscriber. Combined with history replay, zero messages are ever lost.

How Pub/Sub Works

  • Publishers send messages to named channels via WebSocket or REST API.

  • wSocket routes messages to all subscribers in real-time via the distributed broker.

  • Subscribers receive messages instantly with automatic reconnection and catch-up.
