FAQ

What does the Site Audit tool extract?

It extracts the full color palette (grouped by background, text, and accent), all font families with their weights and usage context, every heading (h1–h6) with font size and weight, the technology stack (Tailwind, Bootstrap, Next.js, React, WordPress, etc.), and page metadata like title, description, and OG image.

How accurate is the tech stack detection?

Stack detection analyzes DOM attributes, class names, global JavaScript variables, and HTTP response headers. Confidence scores are included in the JSON output. Detection is most reliable for React, Next.js, WordPress, and Tailwind CSS (90%+ confidence).

How can I get unlimited audits and PNG/PDF export?

The free demo is limited to 3 requests per day for unauthenticated users. With a SnapSharp API key (Starter plan and above), you get unlimited audits, PNG site-book export, and PDF export.
