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.
Comarch
- No pricing is published anywhere on the site for any product line; the only route to cost is a Kontakt z konsultantem (Consultant Contact) request for a quote
- The ERP line is split across three separately scaled products (Optima for SMBs, XL, Enterprise) with no published criteria distinguishing which a given company should quote

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.
Comarch: How much does Comarch cost?
Comarch does not publish pricing online. The company offers enterprise ERP solutions like Comarch ERP Enterprise, Comarch ERP XL, and Comarch ERP Optima. Pricing is determined through custom quotes based on organization size and specific requirements. Contact Comarch sales at (12) 646 1000 or through their consultant contact form to request a quote.
SourceADempiere: 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.
Comarch: What is Comarch's pricing model?
Comarch uses a quote-based pricing model tailored to enterprise customers. The company does not offer self-serve pricing or standardized subscription tiers. Customers must request personalized pricing from the sales team based on their deployment requirements.
SourceADempiere: 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.
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.
