What is it?

LightCraft replaces the Lightroom loop: manage a big library (albums, ratings, flags, field search, virtualized grids) and develop raws non-destructively (Light, color, effects, tone curve, 8-band color mixer, 3-way grading wheels plus 18 built-in presets). It runs pure-Rust raw decoders for DNG, CR2, ARW, NEF, RAF (including X-Trans), RW2, PEF and ORF, and updates a 24 MP raw in about 4 ms per slider move on the GPU develop pipeline.

What can it do?

• Scene-referred, wide-gamut, 32-bit float non-destructive pipeline
• Albums, ratings, flags, field search and virtualized grids
• Pure-Rust decoders: DNG, CR2, ARW, NEF, RAF (X-Trans), RW2, PEF, ORF
• Masking with brush, linear/radial gradients, luminance and color ranges, sky/subject/background
• GPU develop pipeline updates a 24 MP raw in about 4 ms per slider move

Who is it for?

Photographers who want the Lightroom library plus develop loop locally and off the cloud

Pros

• Apache-2.0 open source
• macOS, Windows, Linux native plus web (wasm)
• No account, no cloud, no telemetry
• ~14.1k stars

Cautions

• Labeled In development — large-catalog performance needs independent testing
• Some raw decoders are still being added, so unsupported formats may appear
• Not installed or run during this review
