Eclipse Mosquitto – An open source MQTT broker

I’m confused why this post is on the front page of HN. This isn’t new and they haven’t done a new release or something. Mosquitto is good and used all over the place but not sure why this is being posted.

Since we are into it, just sharing then: I had a lot of success with RabbitMQ + it's MQTT plugin. AFAIK, it actually has the MQTT plugin now baked in by default. Never had any issue at scale, plus you get AMQP in your stack, and you can actually use AMQP to consume the messages originally received over MQTT.

a PITA to scale. or maybe i just don't know how to infra?

i picked mosquitto but had to ditch it for AWS IoT Core and have not looked back.

I've used this for quite a while as a gateway for sparkplugB such that things like ignition can pull our telemetry data (we do agtech monitoring, smart meters, power, water, soil moisture, temp, etc etc)

Is it yet becoming more common to have brokerless protocols like ZeroMQ and Zenoh that do not require having a broker that is deployed separately?

It's written in C. At this point, this is an instant disqualification for a network service.

I looked at MQTT options earlier last year, and the best one was Mochi ( https://github.com/mochi-mqtt/server ), written in Go.

I added TLS support with Let's Encrypt provisioning to it: https://github.com/Cyberax/lenc-mochi

Now the default seems to be EMQX, there's also a possible project to include MQTT5 compatibility in NATS (but they push back because they are selling this in their Entreprise version), what stack do people use here for MQTT?
