Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ADempiere

  • There is no company behind it, so there is no support contract to buy, no SLA, no escalation path and no roadmap commitment; if your implementation partner leaves the market you own the problem entirely.
  • The official website adempiere.net does not resolve, which strands most of the historic documentation and tutorials that search engines still point at and makes onboarding a new developer considerably harder.
  • The last conventional stable release, 3.9.4, is from January 2023, so despite ongoing GitHub activity a buyer evaluating on release cadence sees a project moving slowly.
  • iDempiere, a later fork of the same codebase, absorbed much of the developer community, so ADempiere competes for contributors with its own descendant and is the smaller of the two ecosystems.
  • The interface and the Java Swing heritage feel dated, and staff coming from a modern cloud ERP will need training and will complain; expect resistance from finance and warehouse users during rollout.

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

ADempiere: Should I choose ADempiere or iDempiere?

Look at iDempiere first. It is a later fork of the same codebase with a more active community and a modular OSGi architecture. Choose ADempiere if a specific partner or localisation you need only exists there.

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
ADempiere: Is ADempiere free?

The software is GPL licensed with no licence fee. The cost is implementation, customisation and permanent in-house maintenance, which for a real deployment is substantial.

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
ADempiere: Is the project still alive?

Development continues on GitHub with commits into 2026, but the official website is down and the last stable release is from January 2023. Treat it as maintained rather than actively advancing.

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
ADempiere: What is the application dictionary?

It is the metadata layer inherited from Compiere that stores the definition of every window, field and validation rule as data, so you can change the application without touching source code.
