Compare · 3D device mockup studios
Updated June 11, 2026
MockRocket and DemoDash end at the same kind of asset, a 3D device video of your product, and get there in opposite ways. MockRocket is an editor: you upload screenshots, start from a template or an empty scene, and animate the shot yourself. DemoDash is a generator: paste your URL, and it captures the real site, builds the brand-matched demo, and composes the film for you, nothing to upload and nothing to keyframe.
TL;DR
MockRocket is a browser-based 3D device mockup editor: you upload app screenshots, place them on 3D devices, and compose the shot yourself with templates, a keyframe timeline, and camera controls. DemoDash starts from just your URL: it captures your real site, builds the brand-matched demo, and composes an AI-directed 18-second product film automatically, with licensed beat-synced music baked in.
| DemoDash | MockRocket | |
|---|---|---|
| What you start with | A URL | App screenshots or designs you upload |
| What it makes first | A brand-matched demo dashboard, then the film | A 3D device scene you compose from your upload |
| Scene composition | AI-composed per product (device, mood, backdrop, camera) | Templates, plus a manual timeline with keyframes and camera controls |
| What's on screen | Your real site, scrolling through its actual sections | The screenshots you uploaded |
| Output | 18-second letterboxed film with beat-synced licensed music, as MP4 (HD, or 4K on supported browsers) or GIF | Images and videos up to 4K, in PNG, MP4, WEBM, and PNG-sequence formats |
| Best for | Founders with a live product who want the whole demo built for them | Composing one exact 3D device shot yourself from finished screenshots |
MockRocket is a polished way to compose a 3D device shot yourself, and like DemoDash it runs in the browser (Mac and Windows, in Chrome or Edge) with no install. It gives you a real device library, studio-quality templates, an animation timeline with keyframes and camera controls, a Figma plugin, and exports of stills and video up to 4K in PNG, MP4, WEBM, and PNG-sequence formats, rendered privately on your own machine. If you want to art-direct one exact shot from finished screenshots, that is its home turf.
No. MockRocket's editor starts from app screenshots or designs you upload. DemoDash starts from your product URL: it captures the real site live and builds the film from that, so there is nothing to prepare or upload first.
No. MockRocket gives you templates, a keyframe timeline, and camera controls to compose the shot yourself. DemoDash composes the scene automatically to fit your product, and a Shuffle look control rerolls the device, mood, backdrop, and camera style instantly if you want a different take.
Yes. The MP4 export ships with licensed music baked in, and the film's cuts are synced to the track's beat grid. You pick between two included tracks, or export without music.
Yes. The film exports as HD MP4 everywhere, 4K MP4 on browsers whose encoder supports it, and GIF. MockRocket also states image and video exports up to 4K resolution, so on raw resolution the two are comparable.
DemoDash is free to start, no card required, and Pro is $29 one-time or $9 a month. MockRocket also has a free tier with watermarked exports, and its paid licenses are one-time payments with lifetime access; check its pricing page for current numbers.
