The short version

  • Each has a real cost: 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.; Swagger UI only as good as the specification: a thin OpenAPI file produces thin documentation
  • They diverge on capability: ADempiere covers Application dictionary, Swagger UI covers OpenAPI rendering.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

  • Internal API discovery across teamsnot ADempiere

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.

Swagger UI

  • Only as good as the specification: a thin OpenAPI file produces thin documentation
  • Default presentation is dated compared with modern documentation tools
  • Large specifications render slowly and become hard to navigate
  • Try it out against production needs care with authentication and CORS, and is often disabled as a result

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.

Swagger UI: Is Swagger UI free?

Yes, open source under the Apache 2.0 licence. SmartBear sells commercial SwaggerHub separately.

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.

Swagger UI: What is the difference between Swagger and OpenAPI?

OpenAPI is the specification format; Swagger is the toolset around it, including Swagger UI. The specification was renamed from Swagger to OpenAPI in 2016.

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.

Swagger UI: Can Swagger UI make real API calls?

Yes, through its try-it-out control, though authentication and CORS configuration often mean it is disabled for production APIs.

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.
