Font Awesome Free
Icon Validator

Font Awesome has become the go-to icon library for web developers worldwide, offering thousands of high-quality icons for modern web applications. However, many developers discover too late that they have accidentally used Font Awesome Pro icons in their projects - icons that require a paid license and won't display properly in production when using the free Font Awesome CDN or npm package. This Font Awesome icon validator was created to solve this exact problem before deployment, helping developers validate Font Awesome icons, check Font Awesome compatibility, and ensure all Font Awesome 6 icons in their codebase are available in the free version.

Our Font Awesome checker tool fills a critical gap in the development workflow. Whether you are working with Font Awesome in HTML, CSS, React JSX, Vue templates, or Angular components, this validator parses your code to detect Font Awesome icon references across all formats and styles - including Font Awesome solid icons (fas), Font Awesome regular icons (far), Font Awesome light icons (fal), Font Awesome brands (fab), and Font Awesome duotone icons. The tool instantly identifies which icons require a Font Awesome Pro license and which are available in Font Awesome Free 6.7.1, saving developers hours of debugging and preventing broken icons in production. With support for Font Awesome class names, Font Awesome unicode references, and Font Awesome CSS content properties, our validator is the most comprehensive Font Awesome icon checker available for free.

Beyond simple Font Awesome icon validation, this tool provides intelligent suggestions when Pro-only icons are detected, recommending similar free Font Awesome alternatives that maintain your design intent. Whether you are migrating from Font Awesome Pro to Font Awesome Free, auditing an existing codebase for Font Awesome license compliance, or simply want to verify Font Awesome icon availability before committing code, this validator streamlines your Font Awesome workflow. Export your validation results as JSON or CSV for documentation, share findings with your team, and ensure every Font Awesome icon in your project is properly licensed and will render correctly for your users.
