Simple web interface for mosquitto Dynamic Security administration.
mosquitto recommends either mosquitto_ctrl
(which is a commandline app) or the Management Center for Mosquitto which is web based but I had a hard time to get it running and was disappointed that it mirrored all MQTT traffic into my browser with ~40MB/s.
Either you know what you are doing, or you just use docker:
docker run -e MQTTSERVER=<your mqtt server> -p 8080:80 zivillian/dynamic-security-admin:latest
