About

Siteprint is a Safari extension for Mac that measures any website's design system: colors, typography, spacing, corners, and layout. It then generates a structured prompt that AI coding agents can use to build new pages in that style.

The workflow is simple: open any site in Safari, click the Siteprint icon, and it measures colors with their roles, type scale, spacing, and layout. You can inspect the values directly, or generate a prompt containing all the exact values.

The free version lets you measure colors, typography, and layout, and export the values. The Pro version ($9.99 one-time) adds prompts, DESIGN.md, themes, the ability to mix two sites together, and agent access.

Works with Claude Code, Codex, Cursor, Lovable, and any other AI agent. No account needed, no tracking, no uploads — everything runs locally on your machine.

Why we picked it

Siteprint solves a real problem: how do you communicate a design you love to an AI agent? Instead of manual descriptions or screenshots, it gives you exact values and a ready prompt. The price is reasonable ($9.99 one-time), and privacy is preserved since it runs locally.
