React Scan

React Scan is a JavaScript tool designed to automatically detect and highlight components that cause performance issues in your React application. It seamlessly integrates into your project, whether you choose to add it via a script tag, npm, or other methods. By scanning your app for problematic renders, React Scan helps you identify and address inefficiencies to optimize performance. To get started, simply add the provided script to your app before any other scripts run, ensuring that React Scan can effectively monitor and analyze your components. For more advanced needs, consider exploring additional tools like Million Lint.
