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.; Tendenci self-hosting is a real operational commitment, and organisations without technical capacity should not treat the free licence as a free system
  • They diverge on capability: Apache OFBiz covers Entity engine, Tendenci covers Open-source licence.

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.

Tendenci

  • Self-hosting is a real operational commitment, and organisations without technical capacity should not treat the free licence as a free system
  • The community is small compared with mainstream open-source projects, so answers are harder to find and contributors are few
  • The interface is dated against the commercial association platforms and this is the most common user complaint
  • Fewer integrations than commercial competitors, and building them is a development task rather than a configuration one
  • Feature depth in events and continuing education is behind the specialist commercial systems

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.

Tendenci: Is Tendenci really free?

The software is, under an open-source licence with no per-member fee. Running it is not: hosting, updates, backups and security are the organisation responsibility unless managed hosting is purchased.

Apache OFBiz: What does it cost?

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

Tendenci: Who should choose it?

Organisations with a genuine requirement to control their own data, and the technical capacity to act on it. Choosing it purely to avoid subscription cost usually ends badly.

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.

Tendenci: Can I move my data out?

Yes, entirely. That is the point. Data lives in a PostgreSQL database you control, and there is no vendor holding 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.

Tendenci: How does it compare to Wild Apricot?

Wild Apricot is easier, better supported and better looking. Tendenci is the answer when data ownership is a requirement rather than a preference.

Tendenci: Is it actively maintained?

It is developed openly on GitHub with a small team and community. Check recent commit activity before committing, as with any small open-source project.
