The short version

  • Each has a real cost: Apache OFBiz oFBiz has disclosed repeated critical vulnerabilities including pre-authentication remote code execution and authentication bypass chains, several exploited in the wild, so an internet-facing instance that is not patched promptly is a genuine breach risk rather than a theoretical one.; 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.
  • They diverge on capability: Apache OFBiz covers Entity engine, OpenBOM covers Multi-level BOMs.
  • 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.

Apache OFBiz

  • OFBiz has disclosed repeated critical vulnerabilities including pre-authentication remote code execution and authentication bypass chains, several exploited in the wild, so an internet-facing instance that is not patched promptly is a genuine breach risk rather than a theoretical one.
  • There is no vendor, no support contract and no hosted edition, so every deployment depends on either in-house Java skill or an integrator you find and vet yourself.
  • The screens and default workflows look and behave like enterprise software from the 2000s, and user acceptance in a finance or warehouse team is frequently the reason projects stall.
  • It is a framework rather than a configurable product, so meaningful deployments require Java, XML widget and entity engine development, which puts the real cost in developer months rather than licence fees.
  • Localisation for tax, statutory reporting and payroll is largely absent, so any country-specific compliance requirement has to be built, and that build has to be maintained against upstream releases.

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.

Answered from the vendors’ own pages

Apache OFBiz: Is Apache OFBiz safe to run on the public internet?

Only with disciplined patching. It has shipped fixes for pre-authentication remote code execution and authentication bypass flaws, with CVEs continuing into 2026, and some have been exploited in the wild.

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.

Apache OFBiz: What does it cost?

Nothing to licence. It is Apache 2.0. The cost is Java development, hosting and ongoing security maintenance.

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.

Apache OFBiz: Can I use it as a finished ERP?

Not realistically. It is a framework with reference applications, and most production deployments are custom builds on top of it.

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.

Apache OFBiz: Why choose it over a GPL ERP?

The Apache 2.0 licence is permissive, so an integrator can build and sell a derived commercial product without copyleft obligations.

OpenBOM: Can OpenBOM replace a full PLM?

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