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.; Bazel steep learning curve for developers unfamiliar with build systems
  • They diverge on capability: Apache OFBiz covers Entity engine, Bazel covers Fast incremental builds.
  • 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 Bazel
  • An organisation with strong Java capability that needs an order and inventory data model it can extend rather than configurenot Bazel
  • A business that requires a permissive Apache 2.0 licence because GPL copyleft is unacceptable to its legal teamnot Bazel
  • A team replacing a bespoke in-house order management system that wants an entity model rather than a finished applicationnot Bazel

Bazel

  • Building large monorepos with hundreds of interdependent projectsnot 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.

Bazel

  • Steep learning curve for developers unfamiliar with build systems
  • Initial setup complexity; requires BUILD files and Bazel configuration
  • Verbose error messages can be difficult to debug for new users
  • Smaller community and fewer third-party integrations vs enterprise tools

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.

Bazel: Does Bazel support distributed builds across CI infrastructure?

Yes, Bazel supports distributed execution and remote caching, allowing build work to be distributed across multiple machines and CI agents.

Source
Apache OFBiz: What does it cost?

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

Bazel: What languages can be built with Bazel?

Bazel has built-in support for Java, C++, Go, Python, and Android/iOS development, with additional language support available through custom rules and community extensions.

Source
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.

Bazel: Can I use Bazel for small projects or is it only for large monorepos?

While Bazel excels at handling large projects, it can be used for smaller codebases. However, the setup overhead may not be justified for very small or simple projects.

Source
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.
