SonarLint features

your IDE companion for Clean Code

SonarLint easily integrates into your existing IDE workflow and helps you to commit with confidence. This includes support for cloud-based IDE environments such as GitHub Codespaces and GitPod.

Explore Features

5000+ rules covering wide range of issues

Powerful language-specific analysis detects bugs, code smells, vulnerabilities plus hotspots and supports latest language standards. The large ruleset spans all attributes that contribute to the quality of code—reliability, maintainability, readability, security, and more.

real-time analysis, guidance, and quick fixes

On-the-fly analysis provides instant feedback as you code. More than just a linter, SonarLint highlights coding flaws, even in your AI-assisted code, and explains why the issue is harmful and how to fix it. "Quick fixes" intelligently suggest solutions adapted to your specific code so you can automatically repair flagged issues in real time.

unified team rules and analysis settings

Get coverage at every stage in your dev cycle—IDE to CI/CD and back, ensuring code fit for development and production.  So much more than a linter, when 'connected' with SonarQube or SonarCloud, rules, and analysis settings are synchronized to SonarLint, aligning teams around a single standard of Clean Code.
