Siteprint

Siteprint is a Safari extension for Mac that measures website design and turns it into prompts for coding agents.

Siteprint is a Safari extension for Mac that measures any website's design and converts it into a measured prompt for your coding agent. It captures colors with their roles, the type scale, spacing, and layout to help your agent build a new page with the same styling. Users can inspect pages, export tokens, save to a library, and mix two saved sites into a new style. The tool works with coding agents like Claude Code, Cursor, Codex, and Lovable. It runs locally on macOS 14 or later with no tracking and no uploads. The product offers a free inspection tier and a Pro version available for a one-time payment.
