Are There Tools That Can Evaluate Software Architecture and Maintainability?

Readability and maintainability are partly subjective as well. A tool can highlight complexity or inconsistent structure, but different teams may reasonably prefer different patterns. In practice, the strongest approach is combining static analysis and architecture checks with design reviews, documentation, tests, and feedback from developers who understand the system.

LLMs can review smaller parts of a system and point out possible smells, but they struggle with large products, layered designs, customer needs, and competing business priorities. A decision that looks like poor abstraction or insufficient optimization may actually be the right trade-off for the project. Human judgment is still needed to weigh those trade-offs.

Most tools can only check specific, measurable rules: dependency direction, complexity, duplication, file size, coupling, layering violations, and similar indicators. Whether an architecture is actually “good” depends heavily on the product, team, constraints, and expected change. Those factors are difficult to reduce to a reliable automated score.

There are architecture-oriented tools and techniques, such as dependency analyzers, architecture tests, and fitness functions. They can enforce rules you define—for example, preventing a domain layer from depending on infrastructure—but they generally cannot decide whether those rules are the right design for your system. They’re useful guardrails rather than complete architecture reviewers.
