LightCraft — RAW Photo Editing
ArtCraft
LightCraft is a free, open-source photo library and non-destructive raw developer for macOS, Windows and Linux: it decodes raw files such as DNG, CR2, ARW, NEF and RAF itself, offers light, color and tone-curve controls with brush, gradient and sky or subject masks, and organizes photos in albums with ratings and flags. The official page says it needs no account and has no cloud, telemetry or subscription, and its GitHub README calls it alpha, states a dual MIT or Apache-2.0 license and names gaps such as missing measured camera color calibration for several raw formats. getartcraft.com lists LightCraft as “In development” (checked 13 October 2026).
