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.; Bazel steep learning curve for developers unfamiliar with build systems
- They diverge on capability: ADempiere covers Application dictionary, Bazel covers Fast incremental builds.

What people use each for

- An organisation with a hard requirement to keep financial data on its own servers under its own control with no cloud dependencynot Bazel
- A systems integrator building a vertical ERP product on a permissive base it can fork and ship without paying a licence feenot Bazel
Bazel

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.
Bazel
- Steep learning curve for developers unfamiliar with build systems
- Initial setup complexity; requires BUILD files and Bazel configuration
- Verbose error messages can be difficult to debug for new users
- Smaller community and fewer third-party integrations vs enterprise tools

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.
Bazel: Does Bazel support distributed builds across CI infrastructure?
Yes, Bazel supports distributed execution and remote caching, allowing build work to be distributed across multiple machines and CI agents.
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.
Bazel: What languages can be built with Bazel?
Bazel has built-in support for Java, C++, Go, Python, and Android/iOS development, with additional language support available through custom rules and community extensions.
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.
Bazel: Can I use Bazel for small projects or is it only for large monorepos?
While Bazel excels at handling large projects, it can be used for smaller codebases. However, the setup overhead may not be justified for very small or simple projects.
SourceADempiere: 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.
