MQTT brokers that provide User Interface and REST APIs for User/Topic configuration and management

Mosquitto MQTT

Some known facts whilst working with mosquitto:

• mosquitto is a Command-Line Interface based broker.
• Broker configuration is possible using mosquitto.conf file
• User Management is possible via a password-file and mosquitto_passwd CLI
• Every change either requires the Broker to be restarted (either using systemd or system) or the docker container needs to restarted OR using SIGUP on the Process of Mosquitto

Drawback

• If the Broker is deployed on cloud infrastructure, the administrator has to update the broker everytime and leading to downtimes (although small time intervals)
• If a User Interface is developed for the mosquitto broker, it would required the UI to access shell access which may require root access to perform broker restarts or calling the kill -SIGHUP $pid_mosquitto commands as well as other CLIs (dependent on the way the broker is installed)

Requirements

• Is there a broker out there that lets users manage the broker’s topic + user management plane either via RESTful APIs or via an UI?
• This is critical since it might be easier to handle the broker via such interfaces which mosquitto unfortunately does not provide
