Overview
Generate clean 2D game sprites & animation atlases — component-row pipeline: state rows, alpha cleanup, frame extraction, runtime atlases. Codex/Claude skill. It ranks #57 on GitTiger, gaining +5 stars on November 5, 2026 (UTC).
The project is written in Python and has 374 forks. It was created 5mo ago.
What it is
sprite-gen generates clean 2D game sprites and animation atlases from a single drawing. It is packaged as a Codex/Claude skill, written in Python and released under Apache-2.0. The description sums up the pitch as "one drawing in, game-ready sprites out".
Capabilities described
The pipeline is described as component-row based: state rows, alpha cleanup, frame extraction and runtime atlases. Outputs named in the preview are a transparent sprite atlas (sprite-sheet-alpha.png) with real alpha and no leftover chroma fringe, checked against white backgrounds, plus a runtime manifest carrying absolute frame rectangles, per-state fps and loop flags. Because the manifest gives rectangles, the engine samples them directly instead of guessing a grid.
A further feature called "Breathe" is described as turning a still idle pose into a looping animation by baking deterministic squash and stretch onto frames you have curated, driven from a sidecar file.
The repository topics place it in 2D game development, pixel art and sprite-sheet generation, and list both Claude Code and Codex among the target agents.
Getting started
The supplied evidence does not include installation steps or invocation commands, so they are not reproduced here. Because it ships as an agent skill, expect the README to explain how the skill is installed and invoked.
Caveats
Quality claims about chroma-fringe removal come from the project's own README and were not independently verified.
git clone https://github.com/aldegad/sprite-gen.git

# see README for setupFrequently Asked Questions
What does sprite-gen produce?
A transparent sprite atlas with alpha, a runtime manifest with frame rectangles, per-state fps and loop flags, and looping animation built from curated frames.
Which AI tools can use it?
It is packaged as a Codex/Claude skill; repository topics list claude-code and codex, plus pixel-art and sprite-sheet generation.
Does the engine need a fixed grid?
No. The manifest describes absolute frame rectangles, so the engine samples those instead of inferring a grid.
What licence applies?
Apache-2.0, per the supplied metadata.
