Review: Static Analysis Tools for AI-Generated Code (2026)

Evaluated 6 static analysis tools on a corpus of 10,000 AI-generated code snippets:

1. Semgrep — Best for custom rules. Caught 89% of security issues. Free tier generous. 2. CodeQL — Most comprehensive. Caught 92% but slow (45s avg per scan). 3. Bandit (Python) — Fast, focused on Python security. Caught 78%. 4. ESLint + security plugins — Good for JS/TS. Caught 71% of frontend issues. 5. Snyk Code — Best UX but missed 31% of injection vulnerabilities. 6. SonarQube — Enterprise-grade but heavy setup.

Recommendation: Semgrep for startups, CodeQL for enterprises. Always pair with manual review for logic issues.
