The short version

  • Only Xometry has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Xometry xometry is the counterparty rather than the shop, and the margin between what you pay and what the maker receives is never disclosed, so buyers cannot benchmark the part price.
  • They diverge on capability: Flow Software covers Calculation engine, Xometry covers Instant Quoting Engine.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

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.

Xometry

  • Xometry is the counterparty rather than the shop, and the margin between what you pay and what the maker receives is never disclosed, so buyers cannot benchmark the part price.
  • You usually do not choose or even know which supplier makes the part, so repeat orders can come from different shops with visibly different finish and process consistency.
  • For parts bought repeatedly over years the marketplace margin compounds, and qualifying a shop directly becomes materially cheaper.
  • Instant quotes are geometry-driven and degrade on unusual features, tight tolerances or complex assemblies, where a manual review changes the price after you have planned around the automated figure.
  • Because the software is free and the revenue is in orders, there is no software contract to hold the vendor to; support and continuity are governed by your value as a parts customer, not by a licence.

Answered from the vendors’ own pages

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.

Xometry: Does the Xometry software cost anything?

No. Quoting and Teamspace are free. Xometry earns on the parts you order, with the margin built into the part price.

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.

Xometry: Do I get to choose the shop?

Normally no. Xometry routes the job within its supplier network and remains your contracting party.

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.

Xometry: Is it cheaper than going direct to a machine shop?

For one-off and low-volume work usually yes, once you count sourcing time. For repeat production the marketplace margin makes a direct qualified supplier cheaper.

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.

Xometry: Can it handle ITAR or aerospace work?

It offers ITAR-registered and AS9100 routing on qualifying orders, but you must specify those requirements at quote time.
