Siteprint

About Siteprint

Siteprint is a Safari extension for Mac that measures a website's design properties-colours with their roles, type scale, spacing, corners, and layout. It converts these measurements into a structured prompt formatted for AI coding agents like Claude Code, Cursor, or Codex. The tool runs locally on a Mac and is sold for a one-time payment of $9.99.

Review

Siteprint enters a space where browser extensions that extract design tokens already exist, but it plants its flag in Safari rather than Chrome. The core mechanic is straightforward: scan a page, get a measured breakdown of its visual system, and export that as a prompt an AI agent can use. What makes the output different is the role assignment-colours aren't dumped as a flat hex list but tagged as background, text, accent, or border based on how much real estate they cover.

Key Features

• Inspect mode (free): Measures and displays a site's colours, type, spacing, and layout without requiring payment.
• Role-weighted colour analysis: Colours are ranked by surface area. Trace accents that appear only in badges or status dots get flagged with usage constraints so agents don't treat them as primary palette tokens.
• Agent-ready prompt export: Generates a prompt with exact type sizes and weights, colour roles, corner radii, spacing values, and a section-by-section layout blueprint. A DESIGN.md file is also included in the Pro tier.
• Apple Intelligence integration: On Macs with Apple Intelligence, the on-device model reviews each scan, names colours and type styles, describes the overall feel, and answers questions about the design.
• Library and Compose: The free Library saves scans for later. Pro users can mix two saved site scans into a new combined style using the Compose feature, and agents can read scans directly via MCP.

Pricing and Value

Siteprint uses a single-purchase model: $9.99 once, with no account required. The Inspect feature and Library are free. The Pro tier-which includes prompt export, DESIGN.md, ready-made themes, MCP access for agents, and Compose-is what the one-time payment unlocks. There is no subscription, and pricing for future versions has not been defined.

Pros

• Assigns roles to colours based on measured usage, reducing the guesswork agents typically introduce with raw hex lists.
• Weights colours by surface area and explicitly constrains trace accents, so a one-off badge colour doesn't pollute the generated design system.
• Exports a structured prompt with exact measurements-type scale, spacing, corner radii-rather than a generic style description.
• Runs as a native Safari extension, which means it stays within a single browser workflow and can tap into Apple Intelligence on supported Macs.
• One-time pricing with no account creation keeps the transaction simple.

Cons

• Captures only the currently displayed theme. Sites with separate light and dark modes require two manual scans, and the prompts must be reconciled by hand.
• Does not detect repeated components like buttons or cards. The agent still needs explicit instructions to reuse existing components rather than inventing new ones.
• Siteprint is not well suited for teams that need cross-browser tooling or want to scan a site in Chrome, Firefox, or Edge-it's Safari-only on Mac.

Siteprint fits a specific slot: a Mac-based designer or developer who works in Safari and wants to hand an AI agent a measured design brief instead of a vague style prompt. It won't replace a full design-to-code pipeline, and it doesn't solve component reuse or multi-theme handoff yet, but for single-theme pages where colour roles and exact spacing matter, the output contains concrete constraints agents can follow. The one-time $9.99 price removes friction for anyone curious enough to try it on a real project.
