Launch Faster With Events, Not Endpoints
Your users expect live, adaptive experiences, and event-driven architecture makes it possible.
Why Teams Switch From REST to Events
Always-On Experiences
Push real-time updates in under 100ms worldwide, whether scores are updated, carts are syncing, or sensors are alerting. No polling or manual refreshes are required.
Loose Coupling
Publish once, and any number of services can subscribe. Scale features easily without stitching together WebSockets or refactoring brittle API chains.
AI-Ready Event Streams
Your event log becomes instant training data. Use PubNub Functions or Illuminate to translate, summarize, or predict in real time.
Rapid Iteration
Launch new flows fast by emitting a new event and spinning up a listener. There is no need to rewrite contracts every sprint, no flag days, and no weekend cutovers.
