Code Review

Sonar

A long-established static analysis platform (SonarQube, SonarCloud, SonarLint) that has added AI-powered code review to its existing code quality and security scanning.

Sonar has scanned code for bugs, vulnerabilities, and code smells since SonarQube’s early days, and now extends that static analysis foundation with AI Code Assurance and AI-powered review features that specifically check AI-generated code against the same quality gates used for human-written code.

Why it stands out

Established rule engine — decades of static analysis rules across 30+ languages, not a new AI-only heuristic layer.
AI Code Assurance applies dedicated quality gates to flag AI-generated code that hasn’t been properly vetted.
Deploys everywhere — available as self-hosted SonarQube, cloud-hosted SonarCloud, and the SonarLint IDE plugin.

Good for

Organizations that already rely on Sonar’s quality gates and want AI-generated code held to the same standard.
