Type-X is a free browser extension designed for Chrome, enabling users to test and experience various fonts directly on websites. Ideal for designers and type creators, it allows for real-time font injection, making it easy to visualize how different typefaces appear in context. The extension supports local and custom font files, including WOFF2 formats, ensuring users can test their own designs seamlessly. Additionally, it offers features like variable font testing and custom CSS selectors, providing extensive control over font application.

Notably, Type-X prioritizes user privacy, operating without data collection or ads, and all fonts remain stored locally on the user's device. As an open-source project, it encourages collaboration and transparency, allowing users to access its code and contribute to its development. With support from the Google Fonts team, Type-X stands out as a valuable resource for anyone interested in font design and usability.
