Claude Code Preview is a Chrome add-on designed to enhance the user experience for developers using Claude Code. This free tool provides a split view interface that allows users to see their web deployments on platforms like Netlify and Vercel alongside their chat, eliminating the need to switch between tabs. The interface features an inline URL bar for easy navigation, enabling developers to input their deployment URLs directly within the panel.

Key functionalities include adjustable split view ratios, device mode previews for desktop, tablet, and mobile, and an auto-refresh feature that allows for automatic updates at set intervals. Additionally, users can utilize keyboard shortcuts for quick access and enjoy a persistent state that retains their URL and preferences even after page reloads. This tool significantly streamlines the workflow for developers, making deployment previews more efficient.
