SonarQube is an open-source platform that performs static code analysis to identify quality issues in the codebase. It supports over 25 programming languages and can be integrated with popular CI tools.
SonarQube evaluates projects across categories like Reliability, Maintainability, Security, and Coverage, providing ratings for each dimension.
SonarQube is widely adopted for improving code quality early in the lifecycle to avoid costly rewrites, reduce bugs, and maintain confidence in the codebase over time.
While essential for many teams, in some cases where lightweight tools suffice, SonarQube may not be essential.
