## Description

<strong>Bezel puts your site inside a real device — and the page believes it.</strong>

Not a resized window. A photorealistic device frame with a true emulation layer, so the page reports real touch events, the correct pixel density (DPR), and honest client hints. What you see is what ships.

<strong>Private by design</strong>

Bezel runs locally. The pages you open, your screenshots, your settings — none of it is uploaded, ever. The only time Bezel contacts a server is to verify a Pro licence, and that request carries nothing about you or your browsing.
