Conclusion
Static analysis runs through SonarQube scanners integrated into the build process and detects bugs, vulnerabilities and code smells before deployment. Dashboards show technical debt metrics and security hotspots, and quality gates automatically pass or fail builds based on code quality thresholds. It integrates with CI/CD tools such as Jenkins, Azure DevOps, GitHub Actions and GitLab CI.
SonarSource develops the platform, and its free edition is now called Community Build. Server editions are priced per instance by lines of code, and SonarQube Cloud Team starts at $34/month. It is built for software development teams, DevOps engineers and security analysts. Initial setup and configuration can be complex, since the server has to be set up and connected to code repositories and CI/CD tools.
