Aedes review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

Aedes is an open-source MQTT broker implemented as a Node.js module. It is intended for developers building embedded, self-hosted MQTT messaging systems and IoT backends. The broker can run on stream servers, inside a Node.js application, or through server and Docker configurations. Its protocol coverage includes MQTT 3.1, MQTT 3.1.1, TCP, TLS, WebSocket, and Bridge Protocol support, giving teams several ways to connect clients and route messages.

The main strength is its combination of broker features and Node.js extensibility. Aedes provides message persistence, offline message buffering, authentication and authorization hooks, clustering, high availability, MQTT bridging, and a programmatic API. Its persistence, emitter, and middleware components are pluggable, while MongoDB, Redis, LevelDB, and NeDB are listed as storage integrations. This makes it suitable for teams that want to shape broker behavior within an application rather than adopt a fixed, separately operated service.

Aedes follows an open-source, self-hosted model, so teams choose and manage their deployment configuration. Delivery guarantees are configurable, and clustering and high availability are available when the surrounding architecture is designed to support them. That flexibility will appeal to Node.js developers who need embedded MQTT capabilities, custom hooks, and selectable persistence options. Teams looking for a managed broker experience or a broader messaging platform should consider alternatives with those operating models or wider protocol coverage.

Aedes pros and cons

• Where it wins
  • Supports MQTT 3.1 and 3.1.1 over TCP, TLS, and WebSockets
  • Includes persistence, offline buffering, clustering, and high availability
  • Pluggable components with MongoDB, Redis, LevelDB, and NeDB integrations
• Where it doesn't
  • Requires self-hosted deployment and operational responsibility
  • Focused on MQTT messaging rather than a broad protocol portfolio
  • Configuration is needed for delivery guarantees and high availability
