The short version

  • Each has a real cost: Ignition requires real engineering to implement; it is a platform rather than a finished application; PTC Windchill no pricing is published at any tier, and per-user rates are heavily negotiable on multi-year commitments, so the first quote a buyer receives is rarely the achievable price and small buyers without volume have little leverage.
  • They diverge on capability: Ignition covers Unlimited-client licensing, PTC Windchill covers Part and BOM management.
  • Prices and features above were last checked on 31 August 2026.

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

PTC Windchill

  • No pricing is published at any tier, and per-user rates are heavily negotiable on multi-year commitments, so the first quote a buyer receives is rarely the achievable price and small buyers without volume have little leverage.
  • Implementation dominates cost: data migration, configuration and training routinely account for the majority of three-year total cost of ownership, and large programmes run into seven figures of services.
  • Annual support and maintenance is charged as a percentage of licence value in the low-to-mid teens, so the bill continues indefinitely even in years when nothing is upgraded.
  • Upgrades between major releases are projects rather than updates, particularly where the deployment has been customised, and heavily customised sites often sit several versions behind.
  • The role-based licence tiers mean occasional participants such as purchasing or quality still consume paid seats unless you deploy Windchill Navigate, which is a further product to buy and configure.

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.

PTC Windchill: Is a perpetual licence still available?

PTC has moved decisively to subscription and now positions Windchill as a subscription product. Existing perpetual estates are supported but new perpetual sales are not the default route and should not be assumed.

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.

PTC Windchill: How much does Windchill cost?

PTC publishes nothing. Expect role-tiered per-user subscription plus modules, plus support at a percentage of licence value, plus implementation services that usually exceed the software.

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.

PTC Windchill: Does it require Creo?

No. Creo integration is deepest, but connectors exist for SolidWorks, NX, CATIA and Inventor. Mixed-CAD sites are common.

PTC Windchill: Is it overkill for a hundred-person hardware company?

Usually yes, unless you are in a regulated sector. Below that scale a cloud-native PLM will reach useful state in weeks rather than quarters.
