The short version
- Each has a real cost: Icinga the free core has no vendor SLA, so production incidents are supported through community channels unless a paid support subscription is purchased; 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: Icinga covers Forever Free core, Node-RED covers Visual Editor.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Icinga
- The free core has no vendor SLA, so production incidents are supported through community channels unless a paid support subscription is purchased
- Repository access for enterprise Linux distributions like RHEL and SLES is not free, so organisations standardised on those distributions face a real recurring cost most open source monitoring buyers do not expect
- Enterprise modules are gated behind a separate module subscription, so some functionality demonstrated in marketing material is not part of the free core
- Self-hosting and operating Icinga requires real Linux and monitoring expertise that a commercial SaaS tool would otherwise absorb, so total cost of ownership includes staff time not captured in the licence price
- Pricing for the paid subscriptions varies by geographic region and is not published as a single global rate card, complicating budgeting for multinational organisations
- The web interface and configuration language, while capable, are less immediately polished than a fully commercial tool like PRTG, and initial setup takes longer to reach a usable state
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
