A mockup used to be a picture. You opened Figma, dragged a screenshot into a phone-shaped frame, exported a PNG, and dropped it on your landing page. Done. Static. Pretty.

An interactive mockup is the same idea, but it moves. The device tilts when you hover over it. The screen scrolls when the visitor scrolls the page. The phone reacts to the cursor. Sometimes it breathes — a slow, almost invisible motion that makes the whole thing feel alive instead of frozen.

That is the difference. A static mockup is a photograph of your product. An interactive mockup is your product, sitting on the page, behaving the way it would in someone's hand.

How an interactive mockup works

Under the hood, an interactive mockup is a small 3D scene rendered in the browser. The device — a phone, a tablet, a laptop — is a real 3D model with lighting, shadows, and a screen surface. Your design lives on that screen. The browser draws the scene in real time, so when something changes (the cursor moves, the page scrolls, the visitor clicks), the scene responds.

You do not need to know any of this to use one. Most tools give you a visual editor: pick a device, drop in your screen, choose how it should behave. You get an embed code. You paste it on your site. Done.

Static mockups vs interactive mockups

Static mockups have one job: show the visitor what your app looks like. They do it well, and they are easy. Every design tool exports them in two clicks.

Interactive mockups do a different job. They show what your app feels like. That gap matters more than people expect. A static screenshot tells the visitor "this exists." A moving mockup tells them "this works, it is real, it is yours to try."

The trade-off is weight and effort. A static mockup is a PNG — a few hundred kilobytes, instant load. An interactive mockup is a small WebGL scene — heavier, more setup, a few more things that can go wrong on slow networks. Modern tools handle this with lazy loading and progressive rendering, but the trade-off is real.

Why interactive mockups matter now

Three things changed in the last few years.

Browsers got fast. WebGL is mature, mobile GPUs are strong, and 3D in the browser is no longer a novelty. The same phone that struggled to render a hero animation in 2019 plays a full 3D mockup in 2026 without breaking a sweat.

Landing pages got crowded. Every SaaS uses the same template. The same hero, the same screenshot, the same gradient. A moving mockup is one of the few visual elements that still makes a visitor stop and look.

Attention got shorter. A static image gets a glance. A moving image gets a look. A scene that reacts to the cursor gets a play. That play is the start of trust.

Where you would use one

A landing page hero. The classic spot. Replace the screenshot with a mockup that breathes, tilts on hover, or scrolls in sync with the page.

A portfolio piece. Designers used to drop static mockups into Behance and Dribbble shots. Now the same shot with a live mockup stops the scroll.

A product launch. Product Hunt, Twitter, a launch email. A short loop of a live mockup outperforms a static one on click-through by a wide margin.

A documentation page. Show the feature working, not just the feature sitting still.

A pricing page. Let visitors switch devices and see your product across phone, tablet, and desktop in one place.

What makes a mockup interactive

A few common behaviors:

Hover. The device reacts to the cursor — tilting, lighting up, animating.

Scroll. The mockup animates as the visitor scrolls. Useful for telling a story across a long page.

Load. The mockup plays an entry animation when the section comes into view.

Cursor follow. The device gently tracks the cursor across the screen. Subtle, but it draws the eye.

Click. The visitor clicks and something happens — a zoom, a shake, a transition.

Most tools let you combine these. Hover plus breathing is a common pairing for hero sections.

Common questions

Are interactive mockups bad for performance? They are heavier than a PNG, but not by much when set up right. Lazy loading and a static fallback below the hero handles most of it.

Do they work on mobile? Yes. Modern WebGL runs on every phone shipped in the last five years. Some animations get reduced on small screens by default.

Do they hurt SEO? No. Search engines index the page around the mockup, not the mockup itself. If you want the mockup to contribute to SEO, give it an alt description and a fallback image.

Are they accessible? They should be. A good interactive mockup respects reduced-motion settings, includes keyboard focus where needed, and never traps the visitor.

Do I need to know 3D? No. The whole point of tools like mckp.live is that you upload a screen, pick a device, and get an embed code. No 3D knowledge required.

Getting started

If you want to try one, the fastest path is to embed your first mockup in 60 seconds. Pick a device, drop in your screen, copy the embed code, paste it on your page. The setup is shorter than reading this article.
