Architecture Review: MiroMiro

MiroMiro claims to be Copy any website’s design & assets in one click without DevTools. Let’s look under the hood.

🛠️ The Tech Stack

MiroMiro operates primarily as a Chrome Extension, leveraging the browser’s native capabilities to inspect and extract DOM data. Unlike server-side scrapers (like Puppeteer or Selenium) that might struggle with dynamic content or auth-walls, MiroMiro runs directly in the user’s session context.

• Core Architecture: It utilizes Content Scripts injected into the active tab to access the DOM tree.
• Extraction Engine: The “Magic” relies heavily on window.getComputedStyle() to traverse element styles recursively. It likely maps these computed values (hex codes, rem units, font-families) against a lookup table to generate Tailwind CSS utility classes or standard CSS variables.
• Asset Handling: For images and SVGs, it scrapes src attributes and background-image CSS properties. The “Lottie” extraction likely intercepts network requests or parses the DOM for JSON animation data embedded in player containers.
• Security & Performance: Since it runs client-side, it avoids the latency and IP-blocking issues of cloud scrapers, but it is bound by the browser’s memory limits when bulk-exporting large assets.

💰 Pricing Model

MiroMiro follows a classic Freemium SaaS model, using a “usage-based” gate for its primary value proposition (asset extraction).

• Free Tier: Acts as a trial. Includes the “Inspector Mode” (hover to see styles) and limited asset grabs (approx. 5/month). Useful for occasional checks but too restrictive for professional workflows.
• Starter (€7/mo): Increases limits (approx. 50 grabs/month) and unlocks Design System exports. Targeted at freelancers or developers who need to clone components occasionally.
• Pro (€19/mo): Unlimited extraction and full access to bulk export features. This is the “Production” tier for agencies and power users.

⚖️ Architect’s Verdict

Is this a “Wrapper” or “Deep Tech”?

MiroMiro is a Wrapper. It wraps the powerful but complex functionality of Chrome DevTools into a user-friendly UI. It does not utilize proprietary “Deep Tech” or novel generative AI models to create designs; rather, it uses deterministic logic to extract existing ones. However, the wrapper is high-quality. It solves the friction of manually copying computed styles and mapping them to Tailwind, which is a significant productivity booster.

Developer Use Case:

This tool is “Production Ready” for:

1. Frontend Developers migrating legacy sites to Tailwind CSS who need to extract design tokens (colors, typography) quickly.
2. Design Engineers who want to “steal like an artist”-inspecting how a competitor implemented a specific shadow, gradient, or animation without navigating a cluttered DOM tree.
3. Agencies needing to scrape assets (logos, icons) from a client’s old website where the original design files have been lost.

It replaces the “Right Click -> Inspect -> Copy Styles -> Paste -> Clean up” loop with a single click.
