What is CodeQL (GitHub)?

Discover vulnerabilities before they reach production

CodeQL is GitHub's powerful semantic code analysis engine that treats code as queryable data. By analyzing your codebase with variant analysis, CodeQL detects security vulnerabilities, identifies bugs, and enforces coding standards at scale. Integrated into GitHub Advanced Security, it provides automated code scanning with customizable queries across C/C++, C#, Go, Java, JavaScript, Python, Ruby, Swift, and more. Used internally by GitHub's Security Lab and trusted by thousands of organizations to secure their codebases with over 2,000+ security queries.
