Emitter is a distributed, high-performance publish-subscribe messaging platform built on the MQTT protocol, written in Go. It supports message storage with history and expiry, secure channel keys, TLS encryption, monitoring integrations, and clustered deployment via Docker and Kubernetes.
Use cases
- self-host an MQTT broker for real-time messaging
- build a real-time chat system with pub/sub channels
- stream IoT sensor data from devices at scale
- add low-latency messaging to an online game
- push live updates to web dashboards
- store and replay messages for offline subscribers
- run a fault-tolerant pub/sub cluster in Kubernetes
When to choose
- you need millions of messages per second with low latency
- you want MQTT with message history, expiry, and secure channel keys
- you need a horizontally scalable, self-hosted pub/sub cluster
- your use case is gaming, IoT, or real-time web with binary messaging
When to avoid
- you need a simple message queue with consumer groups like Kafka or RabbitMQ semantics
- you require request/reply or job queue patterns rather than pub/sub
- you cannot accept the AGPL-3.0 license in your product
- you need a managed service without operating your own brokers
