SonarQube is the industry standard for continuous code quality and security inspection, used by over 400,000 organizations worldwide. It analyzes source code for bugs, vulnerabilities, code smells, and security hotspots across 30+ programming languages.
Quality gates define pass/fail criteria for code quality metrics. When integrated with CI/CD pipelines, they prevent code that does not meet quality standards from being merged. This shift-left approach catches issues at the earliest possible stage.
SAST scanning identifies security vulnerabilities including injection flaws, authentication issues, and cryptographic weaknesses. Code smell detection highlights maintainability issues and technical debt. Duplicate code analysis identifies copy-paste patterns that increase maintenance burden.
SonarQube Community Edition is free and open-source. SonarQube Developer Edition adds branch analysis and PR decoration. Enterprise and Data Center editions provide governance, portfolio management, and high availability. SonarCloud offers a hosted version.
