React Device Mockup Frame

Copy Page

A screenshot floating on a page reads as a mock; the same screenshot inside a familiar bezel reads as a real product. That is the whole trade, and it is a good one. Three frames — a browser chrome, a rack-instrument face, and a phone — for the surfaces technical products actually ship on.

Chrome only, on purpose

There is no behaviour here — the traffic-light dots don't close anything, the instrument knobs don't turn. That restraint is deliberate: a mockup frame that half-works invites a reader to click the fake controls and feel the seams. Its job is to be a convincing, silent container for the real thing you built, which lives inside it.

The instrument variant is the one you won't find in a generic mockup kit — a brushed-metal bezel with a recessed screen, a ready lamp, and physical controls down the side, for the DAQ and bench-instrument software that Kelvin exists to dress. The browser frame keeps a locked-padlock URL pill for the SaaS shot; the phone frame is a clean notched slab for the companion app.

Feed it a static image, or — more powerfully — a live Kelvin component tree, so your marketing screenshots are the actual product and can never drift out of date.
