BrandBird alternative: 3D mockups and videos, free
A BrandBird alternative that runs in your browser: 3D device mockups and promo videos, free images, no signup, nothing uploaded, fair source.
BrandBird is a screenshot-beautifying suite — backgrounds, frames, annotations — that grew a 3D device mockup tool with PNG and MP4 export. It is a good all-rounder for people who make a lot of social images. OpenMock is narrower and deeper: a 3D device studio with a video pipeline, no account, and public code. Here is how they line up.
What BrandBird does well
BrandBird is a browser-based suite for polishing screenshots (backgrounds, frames, annotations) that also offers 3D device scenes with keyframed camera and devices, exported as PNG or MP4.
- Broad toolkit for social images beyond device mockups
- 3D scenes with iPhones, iPads, MacBooks and Apple Watch
- PNG up to 4K and MP4 export in the browser
Where OpenMock is different
OpenMock is a browser-based studio for putting screenshots and screen recordings on 3D devices and turning them into promo videos. The differences that matter for someone comparing it with BrandBird:
- Depth over breadth. OpenMock does one thing — device mockups and the promo videos made from them — with a cinematic effects stack (motion blur, depth of field, screen glow, HDRI lighting) and a shot-based timeline with text, logo and audio.
- Local-only, no account. Your files never upload and there is nothing to sign up for.
- Fair source. The code is public under FSL-1.1-MIT.
- Free stills at any size, including transparent PNG, without a plan.
- Procedural current-generation devices rendered in three.js, so they stay sharp at 4K and the page loads fast.

When to stay with BrandBird
If most of what you make is annotated, framed screenshots for social — arrows, highlights, tidy backgrounds — BrandBird's wider toolkit earns its place, and OpenMock is not an annotation tool. Keep it for that and use OpenMock when the deliverable is a device shot or a video.
When OpenMock is the better fit
- You want a promo video with camera moves, motion blur and a timeline
- You want free, unwatermarked device stills without a subscription
- Your unreleased UI should stay on your machine
- You want to inspect or self-host the tool
- You need the iPhone 17 family, MacBook Neo or Apple Watch Ultra 3 as true 3D models
Try it in two minutes

FAQ
Is OpenMock a free BrandBird alternative?
For images, completely: PNG, JPEG and WebP exports are free with no signup or watermark. Video exports are free at up to 720p/30 fps with a watermark; Pro ($5/month or $36/year) removes it and unlocks 4K and 60 fps.
Does OpenMock upload my screenshots or recordings?
No. Rendering, decoding and encoding all happen in your browser with WebGL and WebCodecs. Nothing is sent to a server and there is no account to create.
Can OpenMock annotate screenshots?
No — there are no arrows or callouts. OpenMock composes devices, backgrounds, lighting, text shots and logo shots; add annotations in a screenshot tool before or after.
Can I use OpenMock for both stills and video from one scene?
Yes. The same project exports a transparent PNG for the landing page and an MP4 for the launch post; image exports are free, video needs Pro for watermark-free full resolution.
