The short version

  • Only Aras Innovator has a free tier, so it costs nothing to try first.
  • Each has a real cost: Aras Innovator aras publishes no prices at all, so you cannot sanity-check a quote against a list price and every negotiation starts from the vendor knowing more than you do.; 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: Aras Innovator covers Model-based configuration, PTC Windchill covers Part and BOM management.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Aras Innovator

  • A manufacturer whose current PLM cannot be upgraded because past customisations would break, and who wants configuration that survives releasesnot PTC Windchill
  • An engineering organisation that needs requirements, quality and change management under one data model without buying three modulesnot PTC Windchill
  • A medical device or aerospace firm needing full traceability from requirement to as-built serial numbernot PTC Windchill
  • A company piloting PLM on a real programme using the free 50-user Community Edition before committing budgetnot PTC Windchill

PTC Windchill

  • A medical device manufacturer needing a design history file and audit-ready change control for FDA and MDR submissionsnot Aras Innovator
  • An aerospace supplier reconciling engineering and plant-specific manufacturing BOMs across multiple factoriesnot Aras Innovator
  • An industrial equipment firm managing configurable product families where every unit shipped has a different option setnot Aras Innovator
  • A company standardising on Creo that wants CAD data management and PLM from one vendor rather than twonot Aras Innovator

Where each one falls short

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

Aras Innovator

  • Aras publishes no prices at all, so you cannot sanity-check a quote against a list price and every negotiation starts from the vendor knowing more than you do.
  • The platform ships as a toolkit rather than a configured process, so a first implementation is typically a six to twelve month engagement with an integrator, and services frequently cost more than the first two years of subscription.
  • The Community Edition is capped at 50 named users, gets only annual releases and excludes Aras-performed upgrades, so it is a genuine free tier but a deliberately awkward place to stay.
  • Configuration flexibility invites over-customisation; organisations that model every local exception end up with a system only two internal people understand, which is the same trap they left their previous PLM to escape.
  • CAD connectors are not all equal in maturity, and some are excluded from the base subscription, so a shop standardised on a less common CAD tool should confirm connector scope in writing before signing.

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

Aras Innovator: Is Aras Innovator open source?

No. The source is not open. The Community Edition is free of licence fee for up to 50 named users under a revocable licence, which is not the same thing.

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.

Aras Innovator: Can I buy a perpetual licence?

No. Aras sells subscription only. If a perpetual PLM licence is a procurement requirement, Aras is out.

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.

Aras Innovator: Do upgrades cost extra?

No, and that is the central commercial claim. Aras performs upgrades of subscriber environments, including customised ones, as part of the subscription.

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.

Aras Innovator: How many modules do I have to buy?

One subscription covers all applications. Some CAD connectors are the exception, so confirm yours is in scope.

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.
