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.; Katana MRP the free plan caps SKUs at 30 after a 15 day unlimited period
  • They diverge on capability: Apache OFBiz covers Entity engine, Katana MRP covers Visual production scheduling.
  • 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.

Katana MRP

  • The free plan caps SKUs at 30 after a 15 day unlimited period
  • The Core plan starts at $299 a month and includes one location, with more sold as a usage based add on
  • Core is billed per sales order delivered on top of the base price, so cost tracks throughput
  • Manufacturing management, traceability and warehouse management are separate add ons at $199, $249 and $149 a month
  • A full manufacturing setup therefore stacks to well above the headline $299

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.

Katana MRP: How much does Katana MRP cost?

Katana offers a free plan with 30 SKUs and all core features. Core plan starts at $299/month for unlimited SKUs and users. Usage-based pricing applies to sales orders delivered and additional locations beyond the 1 included. Add-ons like Manufacturing Management cost $199/month.

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.

Katana MRP: How does Katana charge for multiple locations?

Core plan includes 1 location. Additional locations beyond the included location are charged separately with per-unit costs decreasing at higher volumes. Exact pricing for additional locations is calculated based on scale.

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.

Katana MRP: What are the manufacturing add-on costs for Katana?

Katana charges $199/month for Manufacturing Management, $249/month for Traceability, and $149/month for Warehouse Management add-ons. Onboarding package costs $2,000 but is included with Core plan.

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.
