The short version

  • Only FreeCAD has a free tier, so it costs nothing to try first.
  • Each has a real cost: FreeCAD no pricing published; product is completely free and open-source; Ignition requires real engineering to implement; it is a platform rather than a finished application
  • They diverge on capability: FreeCAD covers Parametric modeling, Ignition covers Unlimited-client licensing.

Where each one falls short

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

FreeCAD

  • No pricing published; product is completely free and open-source
  • Donations are optional and voluntary for project support

Ignition

  • Requires real engineering to implement; it is a platform rather than a finished application
  • Steep learning curve, and Inductive Automation runs its own training programme because of it
  • Self-hosted and self-supported by default, so plant IT carries the availability burden
  • Module-based pricing means the entry figure is rarely the final one

Answered from the vendors’ own pages

FreeCAD: How much does FreeCAD cost?

FreeCAD is completely free with no licensing fees, vendor lock-in, sign-up requirements, paywalls, or restrictions. The software is open-source and available for anyone to use and adapt.

Source
Ignition: What does Ignition cost?

It publishes per-server module pricing with unlimited clients, tags and connections, so cost does not scale with how many people use it.

FreeCAD: Does FreeCAD offer optional support or sponsorship?

FreeCAD accepts voluntary donations to support the project. Sponsorship tiers range from $1 per month (Normal Sponsor) to $200 per month (Gold Sponsor), with different visibility levels. One-time donations of any amount are also accepted.

Source
Ignition: Why does unlimited-client licensing matter?

Traditional SCADA is licensed per tag or per screen, which turns adding an operator terminal into a purchase. Ignition removes that ceiling.

Ignition: Is it a finished application?

No, it is a platform. Screens, tags and logic are built for the specific plant, which is real engineering work.
