Sitepeel is a set of free website tools for web developers and designers. Paste a link to clone a site with AI, or get its DESIGN.md, assets, fonts, colors, tech stack, screen sizes or a full-page screenshot. The Sitepeel Chrome extension adds 15 more tools that work on any page you open.
No. Sitepeel (sitepeel.dev) makes free website tools and a Chrome extension for designers and developers. It is not related to Site Peel (sitepeel.io), a website content audit tool.
Yes. The website tools are free and need no install. Clone prompt, DESIGN.md and the asset extractor ask you to sign in after a few runs; lifetime access makes them unlimited and saves your results.
A Markdown file that describes a design system: colors, typography, spacing, corners and components. Link it from your AI agent’s instructions (CLAUDE.md, AGENTS.md or Cursor rules) and Claude Code, Cursor or Codex build interfaces that match it.
It works on public pages. Some sites block automated visits, and pages behind a login need the Sitepeel Chrome extension, which works on the page you have open.
Images, fonts, code and copy belong to the site’s owner. Use them as reference, or ask for permission before you reuse them.
