A CSS Peeper alternative for paste-ready exports
CSS Peeper is a long-running inspector for designers: click an element to read its styles, browse the colors and images on a page, export assets. Stylasso does a different job. It reads the whole page as a design system and hands it to you as code you can paste: CSS variables, a Tailwind v4 theme, a DESIGN.md for AI coding tools, or a shadcn/ui theme.

When to use which
If you inspect elements one at a time, grab images from pages, or want contrast scanning while you browse, CSS Peeper (or the browser's own DevTools) fits that well. If what you need is the system behind a site, ready to drop into a Tailwind project, a shadcn/ui app or a prompt for Cursor or Claude Code, Stylasso is built for that, and its code exports are free.
How Stylasso works
- Open a site and click the Stylasso icon. It reads only that tab, only after the click.
- Check the palette with roles, the fonts, the type scale, spacing, radii and shadows.
- Copy it as CSS variables, a Tailwind v4 theme, a DESIGN.md or JSON, or save a moodboard PNG.
Try it on three sample sites on the home page without installing anything.
