Bezel

什么是 Bezel？

Bezel frames your page in a real iPhone, Pixel, Galaxy or iPad — and the JavaScript inside sees a real phone: true viewport and pixel density, real client hints, touch-device signals. It runs 100% locally in your browser: localhost, staging and logged-in pages just work, and nothing is ever uploaded. 93 devices with verified specs, kept current. Plus screenshots, recording, side-by-side compare, environment spoofing — and markup for quick visual feedback. Free on Chrome, Edge & Firefox.
