In software development, maintaining a modular architecture is challenging, especially in large codebases, leading to issues like circular dependencies and tight coupling between modules. These architectural problems increase maintenance costs, hinder team collaboration, and slow down continuous integration pipelines.

Gauge provides an open-source static analysis tool designed to enforce modular architecture in software projects. By defining and maintaining clear module boundaries, Gauge helps developers prevent architectural decay and improve code maintainability. The tool identifies circular dependencies, visualizes dependency graphs to illustrate module relationships, and accelerates CI pipelines by accurately determining the files impacted by code changes. Gauge enables teams to build and maintain codebases that are easier to understand, test, and evolve.

Gauge is designed for software engineers, architects, and development teams working on large or complex projects who need to enforce modularity, prevent architectural drift, and improve codebase maintainability.
