The short version

  • Each has a real cost: 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; pfSense pfSense CE and pfSense Plus are not simply the same software with a support contract layered on top; Plus is a separately developed edition with its own feature set, and moving between them is a migration, not a toggle
  • They diverge on capability: Node-RED covers Visual Editor, pfSense covers Stateful firewall and NAT.
  • Prices and features above were last checked on 1 September 2026.

Node-RED

  • IoT and device integration workflowsnot pfSense
  • Visual programming for server-side integrationsnot pfSense

pfSense

  • A home user or small business wanting a free, fully-featured firewall on commodity hardware with no licence costnot Node-RED
  • A business wanting an integrated firewall appliance with vendor support, typically buying a Netgate appliance bundled with pfSense Plusnot Node-RED
  • A team wanting to evaluate advanced features like real-time threat intelligence before committing to Netgate hardware or a Plus migrationnot Node-RED
  • An organisation replacing an expensive commercial firewall with an open source alternative while retaining the option to add commercial support laternot Node-RED

Where each one falls short

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

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

pfSense

  • pfSense CE and pfSense Plus are not simply the same software with a support contract layered on top; Plus is a separately developed edition with its own feature set, and moving between them is a migration, not a toggle
  • Running Plus on non-Netgate hardware depends on Netgate's current migration terms, which have changed over time, so a buyer planning to use white-box hardware with Plus should verify current eligibility rather than assume it works as it did previously
  • CE has no official vendor support channel; a business relying on it for production firewalling without a support contract is self-supporting on community forums
  • Some newer features and threat intelligence integrations are Plus-only, so CE users do not get feature parity going forward even though both editions remain under active development
  • Netgate's own appliance pricing and the terms of the CE-to-Plus migration path are not always clearly presented in one place, requiring some digging to understand the real total cost of a Plus deployment on non-Netgate hardware
  • As with any self-managed firewall, security depends on the operator applying updates and correctly configuring rules; there is no managed security operations layer included even in Plus

Answered from the vendors’ own pages

Node-RED: Is Node-RED free?

Yes, Node-RED is completely free and open source. It is available under the MIT License through GitHub and npm package manager. The project is maintained by the OpenJS Foundation.

Source
pfSense: What is the difference between pfSense CE and pfSense Plus?

CE is the free, open source edition installable on any compatible hardware; Plus is a commercial edition from Netgate with additional features and support, typically bundled with Netgate appliances.

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
pfSense: Can I run pfSense Plus on my own hardware?

It is possible through a migration from a CE installation via Netgate's official channel, but the terms and availability of that path have changed over time and should be confirmed directly with Netgate.

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.

Source
pfSense: Is pfSense CE really free with no catch?

Yes, CE has no licence fee and no hardware lock-in, though it comes with community rather than vendor support.
