SonarQube

SonarQube is the industry standard for automated code review: it scans 30+ languages to catch bugs, vulnerabilities, and technical debt before they hit production.

This platform acts as the gatekeeper in your CI/CD pipeline (Jenkins, GitHub Actions, or GitLab). It analyzes source code against 5,000+ rules to identify critical flaws like SQL injections and cross-site scripting (XSS). By enforcing Quality Gates, teams ensure that new code meets strict benchmarks for test coverage (often 80%+) and maintainability. It provides developers with immediate feedback on hotspots, helping them resolve issues in Java, C#, and JavaScript during the development cycle rather than after deployment.
