A CSS Peeper alternative

What CSS Peeper does well, where PikSpec differs, and how to choose. We make PikSpec, so we have kept this to what each tool's own listing says.

In short: PikSpec is a free Chrome extension that covers what most people use CSS Peeper for and adds a full design system view (fonts, colours, spacing, radius and shadows) with exports as design tokens, a DESIGN.md and AI Kits. If you want a polished visual overview of styles and assets and do not need exports for code or AI tools, CSS Peeper is a well-known choice.

Where PikSpec is different

PikSpec turns what you inspect into something you can build with: tokens in five formats and a DESIGN.md that AI coding tools follow.

Build with AI makes Lovable, v0, Claude, Cursor or Claude Code build a new product in the captured style, with a checker that flags anything off-system.

It reads the page as a system: spacing fitted to the grid, colours grouped by role, the components that repeat.
