ESP32 as an MQTT Broker?

[maimariarti]

I want to off-load my RPi3 and make an ESP32 a broker to handle a dozen subs locally, without resorting to online services.
Is there a broker written for ESP32? I see a few people started working on it a couple of years ago but gave up and went back to ESP8266!
ArduinoIDE code would be ideal.
Thanks,
~Mai

I would recommend to use RPI Zero or other <10 US$ "zero" type board (like orangepi zero, nanopi neo, ...) for MQTT broker.

With ESP32 you may try to adapt uMQTTBroker.
