Seeing your website without opening a browser

The normal workflow when building a website: change some code, switch to the browser, refresh the page, look at the result, switch back to the editor. Repeat fifty times a day. Claude Preview shortens this loop. It renders your site in a hidden browser and shows you a screenshot without you ever leaving the terminal. You see the result of your change immediately, right where you are working.

Context switching is expensive. Every time you jump between your editor and browser, you lose a little bit of focus. For visual work (adjusting layout, spacing, typography, colors), you need to see the result constantly. Claude Preview lets you stay in one place and still see what the site looks like after every change. It is a small convenience that adds up to a meaningful productivity gain over a full day of building.

Claude Preview is a plugin for Claude Code (Anthropic's command-line AI tool). Once connected, you can ask the AI to take a screenshot of your running site at any point. It can also click buttons, fill out forms, and check for errors, all from the terminal. The setup is handled through Claude Code's configuration. If you are already using Claude Code, enabling the preview plugin takes a few minutes.

Visual changes: layout tweaks, spacing adjustments, typography, color changes, responsive design testing. Anything where you need to see what the page looks like. For logic changes (does the button actually submit the form? does the API return the right data?), you still want proper tests and a real browser session.
