Claude Desktop adds browser DOM selector

Integrating an interactive, DOM-aware browser panel directly into the Claude Desktop GUI is a massive developer experience improvement that challenges browser extensions and standalone IDE preview tools by making visual debugging and code editing unified. Spawning the browser preview automatically inside the application panel upon running a dev server eliminates tab-switching between the editor and standard web browsers. Additionally, the DOM element selector enables Claude to directly target specific page elements, narrowing down code locations and decreasing the time needed to map visual bugs to source files. Offering this interface across macOS, Windows, and Linux ensures a uniform and powerful desktop agent experience for developers on any OS.
