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.; Flow Software the 11,390 dollar Starter licence caps at 250 measures and events, which a multi-line plant exhausts quickly once each line contributes a dozen calculations, forcing a jump to the 62,230 dollar tier.
  • They diverge on capability: Aras Innovator covers Model-based configuration, Flow Software covers Calculation engine.
  • Prices and features above were last checked on 1 September 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 Flow Software
  • An engineering organisation that needs requirements, quality and change management under one data model without buying three modulesnot Flow Software
  • A medical device or aerospace firm needing full traceability from requirement to as-built serial numbernot Flow Software
  • A company piloting PLM on a real programme using the free 50-user Community Edition before committing budgetnot Flow Software

Flow Software

  • A brewery replacing a fragile network of OEE spreadsheets with governed calculations from the same historian datanot Aras Innovator
  • Reporting specific energy consumption per tonne against an ISO 50001 audit where the calculation method must be documentednot Aras Innovator
  • Feeding Power BI plant dashboards from a historian without giving analysts direct tag-level accessnot Aras Innovator
  • A site that needs lab results typed in and combined with automated tag data in the same yield calculationnot 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.

Flow Software

  • The 11,390 dollar Starter licence caps at 250 measures and events, which a multi-line plant exhausts quickly once each line contributes a dozen calculations, forcing a jump to the 62,230 dollar tier.
  • The Unlimited licence requires every engine on a single server or VM, so any multi-server or multi-site topology goes straight to Distributed at roughly double the price with no intermediate option.
  • Maintenance renews at about fifteen percent of the installed base annually, so a large perpetual estate carries a five-figure recurring cost that the headline perpetual price hides.
  • It is a Windows product with a Microsoft data stack, so Linux or container-native deployment strategies do not apply and the server has to be managed on the plant Windows estate.
  • It calculates and reports but does not collect from equipment itself, so an existing historian or OPC layer is a prerequisite and Flow adds cost on top of that rather than replacing it.

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.

Flow Software: Does Flow publish real prices?

Yes. Starter is 11,390 USD perpetual for 250 measures, Unlimited is 62,230 USD perpetual or 16,595 USD a year, and Distributed is 128,450 USD perpetual or 34,250 USD a year.

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.

Flow Software: Is perpetual licensing still offered?

Yes, at every tier, with the first year of maintenance included and renewal at roughly fifteen percent per year. Subscription is available on Unlimited and Distributed only.

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.

Flow Software: Do I need a historian as well?

Effectively yes. Flow reads from historians, databases and OPC sources; it is a calculation layer, not a data collector.

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.

Flow Software: What counts as a measure?

Each configured KPI or event definition. A single line typically consumes ten to thirty, which is what makes the 250 Starter cap tighter than it looks.
