2D game animations,live in your browser
Drop an export folder in and it plays. Step through the frames, look at the bones and the mesh. Nothing to install.

Six formats, all of them play
- 01
Spine
Skeletal animation · 3.7–4.3
Bones, slots, meshes, skins and events, with a matching runtime for every version.
.skel · .json · .atlas · .png - 02
Aseprite
Sprite sheet
Tags become clips, at the frame delays the file sets. A bare PNG grid is cut into frames in the viewer.
.json + .png - 03

Texture atlas
Frame names become clips; TexturePacker, Phaser and cocos2d atlases too.
.atlas · .txt + .png - 04

Frame by frame, at the file's own delays.
.gif · .apng · .webp - 05
Lottie
Vector animation · .lottie too

Rive
Interactive animation
State machines, inputs and events.

Your files stay on your device
A static site with no server, no account and no upload: what you open is read and played by your browser, and stays there.
Nothing is uploaded
Recognizing, parsing and rendering happen in your browser. The page can only talk to its own origin, so a file cannot leave it, even by accident.
Kept in this browser
What you open is copied into this browser, along with a few settings. Removing it deletes only that copy; the files on your disk are never touched.
No tracking
No analytics, no cookies, no third-party scripts. The host keeps the access logs any CDN does, and nothing more.
Built on other people’s work
The animation runtimes, the interface framework and the example animations the site ships, each under the license it travels with.
