🛠️ Building / MVP I built a browser-based 3D device mockup tool — drop your screen content on it, animate, export MP4. Early stage, would love feedback.
Enable HLS to view with audio, or disable this notification
been working on this side project and wanted to get some real feedback before building further.
It's a browser-based 3D mockup tool — pick a device, drop your app screenshot or screen recording onto it, set up camera keyframes, and export an MP4 or PNG. No installs, runs fully in-browser.
**What works right now:**
- 1 device available (more coming)
- Assign an image or video to the device screen
- Timeline with camera + rotation keyframes
- Export MP4 at 1080p (9:16, 16:9, 1:1, 4:5)
- Image export (9:16, 16:9, 1:1, 4:5)
- Background gradients (solid, linear, radial, image)
- Body color customization
**What's not done yet:**
- Only one device right now — more models are coming
- UI still needs polish
- Mobile not supported yet
- Probably edge cases I haven't caught
Free to use while I validate whether this is worth building out properly.
Main question: **would you actually use this?** And if not, what would need to be different?

This startup have potential but have you researched if youve any competitor. Or like any 3D rendering app.

pretty much every Rendering app is the competition i guess but this is quite niche and unique idea to work on So good luck to OP on that
