Why self-host Mosquitto

What it does
Mosquitto falls into the Internet of Things category of self-hosted software. It is designed to be deployed on your own infrastructure, whether that is a home server, a VPS, or a local machine running Docker.
Community traction

Docker is the most common deployment path. If you are already running containers at home, adding Mosquitto to a compose file is a low-friction way to try it.
Maturity
The current release is 2.0.18. The project has moved past early development and tends to ship stable, documented releases.
