Bezel — Responsive Tester & Device Emulator by Alexander Hagenah

Bezel puts your site inside a real device — and the page believes it.

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.

Free, forever

• 90+ real devices — phones, tablets, foldables, even watches
• Accurate emulation: touch input, pixel density, user-agent, client hints
• Frame localhost, staging, and logged-in pages — nothing to deploy
• Inspect & measure — element size, spacing, fonts, colour contrast
• Eyedropper — sample any pixel on the page
• Viewport and full-page screenshots
• No ads. No account. Nothing you do leaves your machine.

Bezel Pro

• Compare — several devices side by side, live and in sync
• Environment spoofing — geolocation, timezone, language, network, dark mode
• Custom request headers — auth tokens, feature flags, staging gates
• Custom screen sizes — add any device you need
• Presentation mode — hand a clean, framed demo to a client
• Unlimited framed and composite exports

How it works

1. Click Bezel on any tab.
2. Pick a device.
3. The page reflows exactly as it would on the real thing.

Private by design

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. Full policy: https://bezel.tools/privacy
