SpriteLoop

SpriteLoop is a lightweight 2D animation tool built for fast game jam and prototype workflows.

Import character parts, animate with a clean timeline, preview instantly, and export spritesheets in seconds — without the complexity of heavyweight animation software.

Import parts, animate, preview instantly, and export spritesheets.

Features

• Import PNG parts and animate them with position, rotation, scale, opacity, and pivots.
• Build simple cut-out rigs with parent-child links.
• Create multiple animation clips with custom FPS, frame count, and looping.
• Add, move, copy, paste, and duplicate timeline keyframes.
• Choose interpolation per keyframe: Linear, Stepped, Ease In, Ease Out, or Ease In-Out.
• Preview animation with playback, zoom, pan, and onion skinning.
• Resize the canvas, set a background color, and use guide frames for export framing.
• Save self-contained .spriteloop project files with embedded PNG assets.
• Export spritesheets with JSON metadata, PNG image sequences, or GIFs.

⚠️ First public release

SpriteLoop is currently an early alpha and the builds are not code signed yet, so Windows/macOS may show security warnings before launching the app.

Linux packaging was tested on Fedora and Ubuntu, but there may still be distro-specific issues depending on your setup.

If something does not work correctly, please report it in the itch.io community section with:

• your OS/version
• the build you downloaded
• screenshots or terminal errors if possible

This helps a lot while improving cross-platform support.
