Powerful language-specific analysis detects bugs, code smells, vulnerabilities plus security 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.

On-the-fly analysis provides instant feedback allowing you to Learn as You Code. SonarLint highlights coding flaws and provides clear contextual guidance on why the issue is harmful and how to fix it.

Issue highlighting indicates all code locations that contribute to the problem, so you can trace and fix complex flaws.

Quick Fixes intelligently suggest solutions adapted to your specific code, allowing you to automatically repair flagged issues as you code.

Extend capabilities from IDE to CI/CD with Connected Mode to SonarQube/SonarCloud. Synchronize rules and analysis settings and address security hotspots & taint analysis results directly in your IDE. Ensures code that is fit for development and production.

Easy customization allows you to mute rules on-the-fly, mark issues as false positive, or exclude files from analysis. Quick set-up with an out-of-the-box rules profile; customizable to your project's needs and standards.
