Watermark Extension is a Chrome add-on designed for developers, testers, and designers to visually distinguish web environments by overlaying custom text watermarks on any website. This versatile tool offers a variety of styles, including ribbons, banners, labels, flags, and free-floating text, allowing users to select the best option for their needs. The extension also features smart environment presets with standardized color codes for different statuses like Production, QA, Staging, Development, and Confidential, ensuring clarity in web environment identification.

Customization is a key feature of Watermark Extension, allowing users to choose from over six fonts and adjust size, opacity, color, and rotation for their watermarks. The positioning options include a 9-point grid for easy placement or advanced sliders for precise control. Additionally, the extension remembers settings for each website, providing a seamless experience. With a focus on privacy, all data remains local, ensuring minimal impact on page performance.
