Introducing AnimationAPI

Every product launch needs the same set of assets: a ProductHunt gallery image, App Store screenshots, an app-preview video, a Play Store feature graphic. Making them usually means an evening in Blender or After Effects — or settling for a flat screenshot in a stock device frame.

AnimationAPI is a different take: a web-based 3D mockup studio that turns your real screens into photorealistic launch visuals in minutes.

How it works

Pick a template. Orbits, dollies, floats, scroll stories — each one is a tuned camera move over a staged scene.
Drop in your screen. A screenshot, a UI design export, or a screen recording. It lands on a physically modeled phone, tablet, laptop, or floating browser window.
Tweak and export. Adjust colors, text, lighting, and motion with a few sliders, then export exact-pixel stills or MP4/WebM video sized for the store you're launching on.

Rendered in your browser, not on our servers

AnimationAPI runs on WebGPU (with an automatic WebGL2 fallback), so the photoreal rendering — soft shadows, blurred floor reflections, bloom, film grain — happens on your GPU. That has two consequences we care about:

Your media never leaves your machine. Projects and uploads live in browser storage. There is no upload step, no processing queue, no account.
Exports are deterministic. The same project produces the same pixels every time, because every frame is a pure function of the timeline.

Store-spec output, to the pixel

Launch assets have unforgiving specs: ProductHunt gallery images are 1270×760, iPhone 6.9" screenshots are 1320×2868, App Store previews must be 15–30 seconds at exactly 30fps. The export presets encode all of that, and the editor viewport letterboxes to your target size so you compose against the real frame from the first second.

Open the editor and drop in a screenshot — it's free, and there is no sign-up.
