The short version

  • Each has a real cost: Ignition requires real engineering to implement; it is a platform rather than a finished application; Siemens NX siemens NX offers only a 30-day free trial with no published subscription or perpetual license price; buyers must go through a sales process to get pricing, per the vendor's own product page.
  • They diverge on capability: Ignition covers Unlimited-client licensing, Siemens NX covers Advanced CAD.

Where each one falls short

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

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

Siemens NX

  • Siemens NX offers only a 30-day free trial with no published subscription or perpetual license price; buyers must go through a sales process to get pricing, per the vendor's own product page.

Answered from the vendors’ own pages

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.

Siemens NX: Does Siemens NX offer a free trial?

Yes, Siemens offers a 30-day free trial of both Designcenter CAD and NX CAM software that is fully functional. Users can get a hands-on feel for the software without any financial commitment before purchasing.

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.

Siemens NX: Is NX free for students?

Yes, Siemens offers free CAD/CAM Student Edition access to Designcenter and NX for students and educators. Academic offerings are available for those in educational institutions.

Source
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.

Siemens NX: What licensing options does NX provide for different business sizes?

Siemens offers scalable licensing for startups, mid-size companies, and multinational corporations. Designcenter and NX CAM support flexible team-based licensing to match organizational size and manufacturing needs.
