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.; Deltek not one product but a portfolio, including Costpoint, Vantagepoint, Maconomy, Ajera, ComputerEase, GovWin IQ and Replicon, so the right choice depends on the industry before the feature set
  • They diverge on capability: Apache OFBiz covers Entity engine, Deltek covers Project accounting.
  • 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.

Deltek

  • Not one product but a portfolio, including Costpoint, Vantagepoint, Maconomy, Ajera, ComputerEase, GovWin IQ and Replicon, so the right choice depends on the industry before the feature set
  • Pricing is not published anywhere and requires contacting sales
  • Built around project-based industries such as government contracting, architecture and engineering rather than general business

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.

Deltek: How much does Deltek Costpoint cost?

Deltek does not display pricing for Costpoint or other products on its website. Enterprise ERP pricing requires contact with Deltek sales.

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.

Deltek: What is the cost of Deltek Vantagepoint for architecture firms?

Deltek does not publish Vantagepoint pricing on its website. Pricing depends on firm size, employee count, and feature requirements.

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.

Deltek: Do Deltek cloud ERP solutions charge per user?

Deltek offers cloud ERP products but does not disclose per-user, per-month, or subscription rate information on its public website.

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.
