The short version

  • Only Apache OFBiz has a free tier, so it costs nothing to try first.
  • 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.; Plex Manufacturing Cloud there is no on premise option, so a plant whose line-side terminals must keep working through a network outage needs a mitigation plan, and connectivity becomes a production dependency rather than an IT concern.
  • They diverge on capability: Apache OFBiz covers Entity engine, Plex Manufacturing Cloud covers Built-in MES.
  • 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.

Plex Manufacturing Cloud

  • There is no on premise option, so a plant whose line-side terminals must keep working through a network outage needs a mitigation plan, and connectivity becomes a production dependency rather than an IT concern.
  • Every customer runs the same version on the vendor's schedule, so you cannot defer a release to fit around a plant shutdown or a customer audit and must absorb regression testing on the vendor's cadence.
  • Customisation is limited to the platform's own configuration and extension tools, which is what makes the single version model possible but means a process you cannot express within those tools has to change rather than be accommodated.
  • The financial modules are less developed than the operational ones, so groups with complex multi-entity consolidation, statutory reporting in several countries or sophisticated planning requirements often keep a separate finance system alongside it.
  • Country localisations and language coverage are narrower than the tier one vendors offer, which limits the product for a manufacturer expanding into markets with demanding local tax and reporting rules.

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.

Plex Manufacturing Cloud: Can I run Plex on my own servers?

No. It is delivered as multi-tenant cloud software only. If you need an on premise deployment, this product cannot meet that requirement at any price.

Apache OFBiz: What does it cost?

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

Plex Manufacturing Cloud: What happens to my customisations at upgrade time?

There are no customisations in the traditional sense. Extensions are built with the platform's own tooling and are carried forward by the vendor. That is the trade you are making: less freedom to modify, no upgrade project.

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.

Plex Manufacturing Cloud: Has Rockwell's ownership changed the product?

It has placed Plex inside a portfolio with Rockwell's automation, maintenance and analytics products, which pulls the roadmap towards integration with that estate. Whether that helps depends on whether your plant runs Rockwell equipment. Ask about the specific roadmap items you care about.

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.

Plex Manufacturing Cloud: Is the finance module enough on its own?

For a single country manufacturer, usually yes. For a group consolidating several entities across countries with statutory reporting obligations, ask specifically about your requirements, because this is the part of the product most likely to fall short.
