StyleLens is a free Chrome add-on designed for web developers and designers who need to inspect typography and color properties of web page elements quickly. The tool captures essential details such as font family, size, weight, and color values for both foreground and background elements. It also features a tooltip that can be locked to gather information from transient UI components like tooltips and popovers, making it a versatile option for detailed inspection.

The add-on offers user-friendly functionalities, including a one-click copy feature for collected properties and a customizable start delay that allows users to access menus before inspection starts. Preferences such as delay settings and visible fields are stored locally, ensuring a seamless and efficient experience without compromising user data privacy.
