Show HN: Mqtt Broker for 10 Years

Category: infrastructure

Tags: mqtt-broker, esp32, iot

Score: 7.3/10 (Innovation: 6, Technical: 8, Documentation: 8, Utility: 7)

An MQTT 3.1.1 broker that runs entirely on an ESP32-S3 microcontroller, supporting 100 concurrent clients, QoS 0/1, retained messages, OTA updates, a web portal, scheduled publishes, and an embedded Berry scripting VM. It's interesting because it replaces the typical Raspberry Pi or cloud-based MQTT setup with a $10 chip, making edge IoT deployments simpler and more cost-effective.

Target audience: backend devs, iot engineers, devops
