CodeSandbox Watermark Minimizer is a free Chrome extension designed to enhance the user experience on CodeSandbox preview pages. This tool effectively removes the default 'Open Sandbox' overlay, replacing it with a discreet 'dev' link positioned in the bottom-right corner. This adjustment minimizes visual distractions while maintaining access to the sandbox source via a consistent link format, ensuring a smoother workflow for developers.

The extension is particularly beneficial for creating cleaner screenshots and recordings for demos, as it reduces obstructions on mobile and small-screen previews. It functions solely on CodeSandbox preview domains, modifying the user interface locally without affecting the hosted site for other users. Importantly, the extension respects user privacy, as it does not collect or transmit any personal data.
