Announcing Pub/Sub: Programmable MQTT-based Messaging

This post introduces Cloudflare Pub/Sub, a programmable message bus built on MQTT, as a new capability for the Cloudflare Developer Platform. It allows developers to publish and subscribe to messages, filter, aggregate, and modify them using Cloudflare Workers before distribution. This enables real-time messaging, event routing, and moving logic to the edge, complementing existing Workers features like KV, Durable Objects, and R2 for building full-stack applications.
