Your IDE is the best place to catch coding issues. SonarLint enables you to code better with on-the-fly analysis and support for hundreds of deep static analysis rules to detect common mistakes, tricky bugs, and security issues.
Get maximum coverage for your programming language with no installation overhead or lengthy setup. Just install the plugin and continue to code while SonarLint assists you in the background. It's the only in-IDE solution you'll ever need.
The quality of your codebase shouldn't be a topic of concern when the code you commit is always clean. A shift-left approach with SonarLint allows early detection of issues, so you can get it right the first time and avoid costly rework downstream.
SonarLint helps developers of all skill levels make better coding decisions and provides them the knowledge & guidance they need to fix coding mistakes, uncover best practices, and learn along the way.
SonarLint easily integrates into your existing IDE workflow and helps you to commit with confidence.
Install For Free -->Powerful language-specific analysis detects Bugs, Code Smells & Security Vulnerabilities and supports latest language standards. The large ruleset spans all attributes of code—reliability, maintainability, readability, security, quality, and more.
On-the-fly analysis provides instant feedback as you code. SonarLint highlights coding flaws and provides clear guidance on why the issue is harmful and how to fix it.
Issue highlighting includes all the code locations that contribute to each issue. A listed view in the SonarLint panel lets you focus on the most important ones first.
‘Quick fixes’ intelligently suggest solutions adapted to your specific code so you can automatically repair flagged issues in real-time.
‘Secret’ detection rules identify confidential user or system-level information in source code or language-agnostic files before they are committed.
Easy customization allows you to mute rules on-the-fly, mark issues as false positive, or exclude files from analysis. Start with a default rule profile and customize it based on your project's need and standard.
Get coverage at every stage in your dev cycle—IDE to CI/CD and back. When 'connected' with SonarQube or SonarCloud, rules, and analysis settings are synchronized to SonarLint, aligning teams on a single standard of code health.
Extend the capabilities of SonarLint by addressing security hotspots detected by SonarQube and taint analysis results from SonarQube/SonarCloud directly in your IDE.
SonarLint is a valuable companion to prevent coding errors and potential performance issues in my code.
