The short version
- Each has a real cost: Altium 365 the 1,990 US dollar Altium Develop entry price is capped at five authors in total, so a growing team hits a forced migration to Agile Teams with unpublished pricing exactly when headcount is rising.; PTC Windchill no pricing is published at any tier, and per-user rates are heavily negotiable on multi-year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: Altium 365 covers Shared workspace, 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.
Altium 365
- The 1,990 US dollar Altium Develop entry price is capped at five authors in total, so a growing team hits a forced migration to Agile Teams with unpublished pricing exactly when headcount is rising.
- Add-on portals are expensive per seat; BOM Portal has been quoted at around 1,999 US dollars per user per year and MCAD CoDesigner at around 499, so the real cost of a working configuration is well above the headline.
- It is tied to Altium Designer; there is no meaningful use of the platform for teams designing in KiCad, OrCAD or Allegro, which makes it a lock-in decision rather than a tooling one.
- Renesas acquired Altium in 2024, and a semiconductor manufacturer owning the design tool used to select competing semiconductors is a conflict some buyers will want addressed in writing before uploading a library.
- Repeated repackaging, from Altium 365 Standard and Pro tiers to Altium Develop and Agile Teams, has made renewal comparisons difficult and customers have found their previous tier no longer maps to anything on the price list.
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
Altium 365: Is Altium 365 free with Altium Designer?
A workspace is included with a current subscription, but the higher tiers, extra authors and the add-on portals are chargeable. The unlimited non-author users are genuinely included.
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.
Altium 365: What does it cost?
Altium Develop starts at about 1,990 US dollars a year for one author plus a workspace, with extra authors at 995 US dollars each up to four more. Larger teams are quoted.
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.
Altium 365: Who owns Altium now?
Renesas Electronics completed its acquisition of Altium in 2024. Altium 365 is therefore a Renesas-owned platform.
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.
Altium 365: Can I keep design data on my own servers?
Yes, through the Enterprise on-premise workspace server, but that is a quoted product and most of the newer portal features assume the hosted platform.
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.
