What it does
SonarQube Server runs in an organization's own environment and analyzes code for issues across supported languages, frameworks, and infrastructure-as-code formats. Scanners connect projects to the server, where teams inspect findings and define quality gates for new code or pull-request workflows. It is the analysis and policy stage of a delivery pipeline, not the build runner or deployment system.
Put analysis on the path to a merge
A typical workflow has a self-managed SonarQube Server instance, a scanner in the build environment, and a project connected to the server. The scanner analyzes the checked-out source and sends results back; developers then review issues and the project's quality-gate status. Sonar's documentation describes integrating analysis with CI and supported DevOps platforms, including merge or pull-request checks.
For JavaScript and TypeScript projects, the documented NPM scanner can be added as a development dependency or run with npx. A team might call it from its CI job after installing dependencies, then use a quality gate to prevent newly introduced issues from silently passing review. The exact gate conditions and supported language coverage should be selected from the server edition and scanner documentation.
SonarQube Server is self-managed, so the organization operates the server and its supporting database. The free Community Build provides a no-charge starting point, while Developer, Enterprise, and Data Center editions are licensed per instance per year according to lines of code. Commercial capabilities and support differ by edition. SonarQube Cloud is a separate hosted service and should not be confused with this on-premises/server product.
Strengths
- Analyzes code in a CI workflow and returns findings to a central project view.
- Quality gates can express a team's release-readiness policy for analyzed code.
- A free Community Build is available alongside paid self-managed editions.
Watch out for
- The server is self-managed and has supporting infrastructure requirements, including a database.
- Paid server editions are licensed per instance and by lines of code, and capabilities vary by edition.
Best for
- Adding static analysis and quality checks to CI before a merge
- Teams that need to host code analysis in their own environment
- JavaScript or TypeScript teams using a scanner from an NPM-based build
