Craws 🦀🎨

claws + draws — a blazing-fast, automation-first image editor for developers. Written in Rust.

Craws treats image editing as pipelines: chains of parametrized operations you can run from a GUI, a headless CLI, CI, or drive from an AI agent over MCP. The engine is tiled, content-hash cached, and works in linear-light f32 — tweak one parameter and only the affected tiles of the affected steps recompute.

Status: pre-alpha (M0). Engine core + CLI pipeline runner. No GUI yet (Tauri 2 + React planned).

Try it

cargo run --release -p craws-cli -- run pipeline.json --in photo.jpg --out result.webp

pipeline.json:

{
  "version": 0,
  "steps": [
    { "op": "resize", "width": 1600 },
    { "op": "exposure", "stops": 0.5 },
    { "op": "crop", "x": 100, "y": 50, "width": 1280, "height": 720 }
  ]
}

cargo run -p craws-cli -- ops lists available operations.
