About Lizard Studio — Claude Code & ChatGPT Side Panel

Lizard Studio is a Chrome extension that puts Claude Code or Codex right in the side panel, next to whatever you're building. It sees the DOM, the console, the network tab, even the pixels on screen, so you stop flipping to a terminal to describe a bug in words. WHAT YOU GET • The real agent harness, running with the same agent, models, and permissions you already use in the terminal, just pointed at your browser now • Browser tools out of the box: read the DOM, watch console and network, click, type, screenshot, navigate. Anything that changes the page asks you first • A design toolkit built in: click to select any element, annotate with a marker, sample colors with an eyedropper, measure gaps, drop in a grid, preview any device size PRIVACY Nothing leaves your machine except what you send to the model provider.
