LightCraft is a photo library and raw editor inspired by Adobe Lightroom. Everything is non-destructive, so your original files are never changed, and it runs natively on macOS, Windows and Linux and in the browser through WebAssembly.

Highlights

• A scene-referred, wide-gamut, 32-bit floating-point processing pipeline
• Exposure, contrast, highlights, shadows, whites and blacks, with edge-aware local tone mapping
• White balance by temperature and tint, color grading and masking
• Presets, before and after comparison and a built-in library
• Can be driven end to end by AI agents over MCP

Its tagline sums up the approach: your photos, your pixels, your machine.
