Lightcraft

Lightcraft is an open-source photo library and raw development application built in pure Rust.

LightCraft is an open-source photo library and raw development application designed as a clean-room reimplementation of Adobe Lightroom. It features a scene-referred, wide-gamut, 32-bit float pipeline running natively on macOS, Windows, and Linux, as well as in the browser via WebAssembly. Every adjustment is non-destructive, utilizing modern perceptual color space OkLCh and an edge-aware local tone mapping engine. The application supports inputs including DNG, Canon CR2, Sony ARW, Nikon NEF, Fujifilm RAF, Panasonic RW2, Pentax PEF, Olympus ORF, JPEG, PNG, TIFF, WebP, PSD, and JPEG XL. What sets it apart is its comprehensive architecture built for AI agents over MCP, allowing complete control through a command registry, CLI, and control channel.
