The diagnostic engine for web quality.
SiteScan.top renders your site like a real user, then dissects it across every dimension of web quality — surfacing every broken link, dead form, and hidden error with surgical precision.
Where errors live, visualized.
As you read the report, anatomy rules connect each finding to the exact element on your page — so you see not just what's wrong, but where.
- Render like a user
- A real headless browser loads every page, executes JavaScript, and waits for network idle — exactly as your visitors experience it.
- Act like a user
- AI agents fill forms, click buttons, and navigate flows to catch broken validation and submission errors no static scan can find.
- Report like an engineer
- Prioritized issues with reproduction steps, fix suggestions, and one-click PDF export for stakeholders.
