The short version

  • Only OpenBOM has a free tier, so it costs nothing to try first.
  • Each has a real cost: OpenBOM pricing has three axes, editing seats plus data record count plus per-seat CAD add-ins at $25 to $45 each, so the real annual cost is well above the advertised per-seat figure.; Rockwell FactoryTalk factoryTalk is a brand, not a product, so a quote that says FactoryTalk may cover any of six separately licensed things; buyers repeatedly find that the demo they saw needed View plus Historian plus a Hub subscription.
  • They diverge on capability: OpenBOM covers Multi-level BOMs, Rockwell FactoryTalk covers FactoryTalk View SE and ME.
  • 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.

OpenBOM

  • A hardware startup replacing a shared BOM spreadsheet before its first contract manufacturing runnot Rockwell FactoryTalk
  • A contract manufacturer sharing structured BOMs with customers who should see but not edit themnot Rockwell FactoryTalk
  • An electronics team pulling BOMs straight out of Altium and mechanical CAD instead of retyping themnot Rockwell FactoryTalk
  • A small manufacturer that needs part numbering and revision discipline but cannot fund a PLM projectnot Rockwell FactoryTalk

Rockwell FactoryTalk

  • A plant standardised on ControlLogix that needs supervisory HMI without building and maintaining an OPC layer between controller and screennot OpenBOM
  • A hybrid manufacturer needing ISA-88 batch execution audited against recipes, where FactoryTalk Batch is already validated in the industrynot OpenBOM
  • Consolidating machine-level HMI screens across many Allen-Bradley lines under one tag model and one alarm schemenot OpenBOM
  • Adding a plant historian quickly where the site has Rockwell distribution support but no PI administrator on staffnot OpenBOM

Where each one falls short

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

OpenBOM

  • Pricing has three axes, editing seats plus data record count plus per-seat CAD add-ins at $25 to $45 each, so the real annual cost is well above the advertised per-seat figure.
  • Paying yearly nearly halves the seat price, from $55 to $30 and $165 to $90, so monthly billing carries an unusually heavy penalty for teams that want flexibility.
  • Change management, revision control and CAD file management are absent from the entry Team plan, so the cheapest tier is a catalogue rather than a working PLM.
  • It lacks the approval workflows, effectivity dating and audit depth that regulated medical and aerospace suppliers need, so companies pursuing ISO 13485 or AS9100 typically migrate away.
  • Record count is metered separately and a large imported part library can push a small team into a higher data tier without adding a single user.

Rockwell FactoryTalk

  • FactoryTalk is a brand, not a product, so a quote that says FactoryTalk may cover any of six separately licensed things; buyers repeatedly find that the demo they saw needed View plus Historian plus a Hub subscription.
  • Licensing units differ per product, tags for Historian, display tags and clients for View, another scheme for Optix, which makes forecasting the cost of a plant expansion genuinely hard.
  • The migration of products onto FactoryTalk Hub subscriptions converts what used to be a perpetual licence into an annual payment where lapsing stops the software, changing a capital purchase into an operating one you cannot exit.
  • Value drops sharply outside an Allen-Bradley estate; against a Siemens or Mitsubishi PLC you are back to OPC UA and lose the main reason to buy FactoryTalk at all.
  • There is no public price list and buying is through distribution, so two plants of identical size in the same company can pay materially different amounts depending on when and how they negotiated.

Answered from the vendors’ own pages

OpenBOM: Is OpenBOM free?

There is a genuine free tier limited to 2,000 data records and aimed at non-commercial and educational use. Commercial teams start at $30 per seat per month billed yearly.

Rockwell FactoryTalk: Is FactoryTalk Historian the same as AVEVA PI?

It is built on the PI engine under an OEM arrangement, tuned for Rockwell integration. If you already run PI enterprise-wide, buying Historian too usually duplicates a system you have.

OpenBOM: Do I pay for people who only look at BOMs?

No. Read-only users are unlimited and free on every paid plan, which is the main reason the total cost undercuts seat-for-seat PLM tools.

Rockwell FactoryTalk: Can I still buy FactoryTalk perpetually?

Some products yes, but the direction is toward FactoryTalk Hub subscriptions. Confirm per product before assuming a capital purchase is available.

OpenBOM: Are the CAD add-ins included?

No. They are $25 per seat per month billed yearly, $45 monthly, and require an active Team or Company subscription.

Rockwell FactoryTalk: Does FactoryTalk work with non-Rockwell PLCs?

Yes, through OPC UA and drivers, but the native tag browse advantage disappears and the case for FactoryTalk over a cheaper independent SCADA weakens.

OpenBOM: Can OpenBOM replace a full PLM?

For a startup, usually yes. For regulated manufacturing needing controlled workflows and full audit trails, no.

Rockwell FactoryTalk: Where do I find pricing?

You cannot without a distributor. Rockwell publishes no list pricing for the FactoryTalk portfolio.
