The clearest difference between SonarQube and StackHawk is pricing β SonarQube is freemium (has a free tier), while StackHawk is subscription (no free tier). Beyond that, lock-in β SonarQube has low lock-in (OSS Community edition available), whereas StackHawk has low lock-in (Based on OSS ZAP scanner). The stated fit for both tools is similar on paper: SonarQube is pitched as SAST and code quality platform detecting security vulnerabilities, bugs, and code smells across 30+ programming languages, while StackHawk is pitched as Developer-centric DAST tool running application security tests in CI/CD using OpenAPI and GraphQL specs. On the strengths side, SonarQube is cited for UGC platforms (social, marketplace), while StackHawk is cited for Chat/messaging apps. The honest trade-off: both SonarQube and StackHawk are the wrong call for internal projects. Choosing between them should come down to the constraint that actually binds your workflow, not surface-level overlap. On developer experience the data shows SonarQube at 5/5 and StackHawk at 5/5, with transparency at 4/5 and 4/5 respectively.
