The verdict
ArchUnit appears in 1 AI-ranked category — best position #2 for java frameworks for modular monoliths.
The de facto framework-agnostic architectural governance tool for Java; provides unmatched flexibility for defining and testing package encapsulation, directional dependency rules, and modular slices via standard unit tests across any DI framework. Flags a near-tie with Spring Modulith for non-Spring projects.
Where ArchUnit falls short, per the models
- Gemini Validates boundaries purely at test execution time rather than at compile-time or runtime, allowing architectural leaks to exist unchecked during active development until the test suite is run.
Top alternatives per the models: Spring Modulith · Quarkus · jMolecules · Axon Framework

Boards re-poll weekly and the models change their minds. One short email only when ArchUnit's standing moves — a rank change, a rival overtaking, or new reasoning from the models. Nothing otherwise.
