The short version

  • Each has a real cost: MQTT mQTT is an open-source protocol standard with no commercial pricing; not a commercial product; Node-RED the Node-RED editor ships unsecured: anyone who can reach its IP address can open the editor and deploy changes until adminAuth is configured
  • They diverge on capability: MQTT covers Publish-Subscribe, Node-RED covers Visual Editor.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

MQTT

  • MQTT is an open-source protocol standard with no commercial pricing; not a commercial product

Node-RED

  • The Node-RED editor ships unsecured: anyone who can reach its IP address can open the editor and deploy changes until adminAuth is configured
  • HTTPS is off by default and must be enabled through the https setting
  • HTTP endpoints and dashboards exposed by flows are unauthenticated unless httpNodeAuth is configured separately
  • All three security layers are optional additions the administrator must implement by editing the settings file

Node-RED: Does Node-RED offer commercial support?

Node-RED itself is free and community-supported. FlowFuse, Inc. was founded in 2021 as a separate commercial entity offering enterprise support and a professional platform for Node-RED deployment, but FlowFuse is not Node-RED.

Source
Node-RED: What is Node-RED pricing model?

Node-RED has no pricing model. It is completely free open source software. Commercial support and hosting options may be available separately through third-party providers like FlowFuse, but the core software is not sold.
