Bezel - See your site on the real device inside your browser

by
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.

Hi Product Hunt, I'm Alex. I build websites on the side, and for years my routine was the same: check the layout in the browser's device mode, ship it, then open the site on my own phone and tablet and find that something was off anyway. Device mode resizes the window and swaps the user agent string, but the page still gets desktop client hints, renders at 1x, and never sees touch. A real phone is simply a different environment. I wanted a way to see my site the way a phone actually sees it, without sending anything to a cloud service and without a device farm subscription. I couldn't find one, so I built it. Bezel frames the tab you already have open inside a real device. The page loads its mobile bundle, renders at the device's true viewport and pixel density, receives the right client hints, and detects a touch device. There are 93 devices with verified specs, from current iPhones and Samsungs to foldables and an Apple Watch. Because it runs entirely in your browser, localhost, staging environments and pages behind a login work with no setup. Your session comes along, and nothing you test leaves your machine. There is no account. Beyond the emulation there is an inspector, device-framed screenshots and recordings, a side-by-side compare view, environment spoofing with a readout of what the page actually sees, and a small markup tool for annotating what you find and sharing it. The free tier is the full emulation with all 93 devices, the inspector and screenshots. Pro adds recording, compare, spoofing and review exports. If you leave your URL in a comment I will reply with your site framed on an iPhone and a Samung (or any other from the list). I would genuinely appreciate your feedback, including the critical kind. That is what has shaped the tool so far. Thanks for taking a look. Alex

Love that this runs locally — huge for testing logged-in flows. One thing I'd love is a way to throttle the network connection per device, so I can actually feel how a site performs on a spotty 3G iPhone versus a Pixel on wifi. Right now I have to use DevTools separately, which kind of breaks the realism.

the verified specs on 93 devices is honestly the kind of detail most tools skip, and it makes the local-only approach feel trustworthy instead of gimmicky.

finally something that actually spoofs client hints properly instead of just resizing the viewport. tested a logged-in staging page and it just worked, no extensions or uploads needed.
