Paste any public URL and we will analyse how it behaves on common mobile, tablet, and desktop breakpoints.

Examples:

How to get a clean report

- Prefer production URLs so we can analyse real content and assets.
- Avoid pages behind logins or firewalls because the scanner must be able to reach the URL.
- Re-scan after each major layout change to track improvement over time.

Res uses static analysis to approximate how your layout behaves at common breakpoints. Always confirm critical journeys manually before shipping.
