Overview

Best for: Engineering teams that need automated code verification in CI/CD and pull requests.

Use cases

  • Enforce quality gates
  • Detect vulnerabilities and secrets
  • Review AI-generated code before merge

Most common use case example

Add SonarQube to CI so every pull request is scanned and blocked if it introduces critical issues.

Pricing and free plan

Pricing model: Freemium/paid. Official Sonar pricing includes free/community options and paid cloud/server plans based on lines of code and features.

Free plan / trial assessment: Free/community options exist but lack some enterprise, branch, governance, and support features.

Limitations

Rule tuning is required to reduce noise; paid LOC-based pricing can matter for large repos.
