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.; Tryton ordinary series are supported for only one year, so any deployment not pinned to a long term support major version needs a funded upgrade project every twelve months, which is the largest hidden cost of running Tryton.
  • They diverge on capability: ADempiere covers Application dictionary, Tryton covers Modular installation.
  • Prices and features above were last checked on 31 August 2026.

  • A company with in-house Python developers that intends to extend the data model rather than configure a closed productnot ADempiere

  • A distributor needing multi-company books in one database with analytic accounting on topnot 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.

Tryton

  • Ordinary series are supported for only one year, so any deployment not pinned to a long term support major version needs a funded upgrade project every twelve months, which is the largest hidden cost of running Tryton.
  • There is no vendor to buy support from, only a list of independent service providers, so procurement teams that require a single accountable supplier with an SLA have to construct one themselves.
  • The module ecosystem is far smaller than Odoo or ERPNext, so region-specific tax rules, payroll and industry add-ons frequently have to be written rather than installed.
  • Out of the box reporting is thin and there is no built-in business intelligence layer, so most deployments end up exporting to an external tool to get management reporting.
  • Documentation and community discussion are functional but sparse compared with commercial ERPs, which lengthens implementation for teams that have not worked with Tryton before and makes hiring experienced consultants harder.

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.

Tryton: What licence is Tryton under?

The platform and official modules are GPL-3.0-or-later. There is no paid enterprise edition.

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.

Tryton: How long is a release supported?

Series are released every six months and supported for one year. Major versions get five years of long term support, so pin to an LTS release unless you can fund annual upgrades.

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.

Tryton: Is there a hosted version from the project?

No. The foundation lists independent service providers who offer hosting and support commercially.

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.

Tryton: How does it differ from Odoo?

Tryton has no open core split, so there is no paid edition holding back features, but the module ecosystem and partner network are much smaller.
