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.; MUI escaping the Material Design look takes more theming effort than teams expect
  • They diverge on capability: Apache OFBiz covers Entity engine, MUI covers Large component set.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Apache OFBiz

  • A systems integrator building a vertical industry product on a permissively licensed ERP core it can redistribute commerciallynot MUI
  • An organisation with strong Java capability that needs an order and inventory data model it can extend rather than configurenot MUI
  • A business that requires a permissive Apache 2.0 licence because GPL copyleft is unacceptable to its legal teamnot MUI
  • A team replacing a bespoke in-house order management system that wants an entity model rather than a finished applicationnot MUI

MUI

  • Building an admin or internal application quickly with components that already worknot Apache OFBiz
  • Teams needing accessible complex widgets without building themnot Apache OFBiz
  • Products where Material Design is an acceptable or desired starting pointnot Apache OFBiz

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.

MUI

  • Escaping the Material Design look takes more theming effort than teams expect
  • Bundle size is significant, and careless imports pull in far more than needed
  • Advanced components such as the full data grid require a paid licence
  • Major version upgrades have historically required real migration work

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.

MUI: Is MUI free?

The core library is open source and free. Advanced components, including the full-featured data grid, require a paid licence.

Apache OFBiz: What does it cost?

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

MUI: Can MUI look non-Material?

Yes, through the theming system, but a substantial departure takes real work. Teams wanting full design control often prefer unstyled primitives instead.

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.

MUI: Does MUI handle accessibility?

Components follow WAI-ARIA patterns by default, which is a large part of why teams adopt it.

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.
