About SonarQube
SonarQube is the code quality and security platform that analyzes every pull request for bugs, vulnerabilities, code smells, and technical debt. 300,000+ organizations use SonarQube, including BNP Paribas, Microsoft, and IBM.
SonarQube''s quality gates: set conditions (0 new bugs, 0 new vulnerabilities, coverage >80%) that must pass before a PR can be merged. The Quality Gate is binary — pass or fail — making code standards enforceable automatically.
What SonarQube detects:
- Bugs: null pointer dereferences, resource leaks, SQL injection vulnerabilities
- Security hotspots: code that needs human review for security implications
- Code smells: duplicated blocks, overly complex methods, poor naming
- Coverage gaps: untested code paths highlighted per PR
SonarQube vs Snyk: SonarQube analyzes your own code for bugs and code smells. Snyk analyzes your dependencies for known CVEs. They are complementary — many teams use both.
SonarCloud: the hosted SaaS version of SonarQube. Free for open-source projects. Paid for private repositories. Eliminates self-hosting operational overhead.
Community Edition limitations: no branch analysis (only main branch), no pull request decoration (comments on PRs showing issues inline). Branch analysis and PR decoration require Developer Edition ($150/year).
