Show HN: CSS Studio. Design by hand, code by agent

Source: Hacker News

Overview

Hi HN! I’ve just released CSS Studio, a design tool that lives on your site, runs in your browser, and sends updates to your existing AI agent, which edits any codebase. You can try the latest version directly on the site.

How it works

• Open your site in dev mode and start editing it.
• In your agent, run /studio, which then polls (or uses Claude Channels) an MCP server.
• Changes are streamed as JSON via the MCP, along with viewport and URL information.
• The skill includes instructions on how best to implement those changes.

Features

• Visual editing tools you’d expect from a design tool
• Text editing
• Style editing
• Animation timeline editor
