darktable

darktable is an open-source photography workflow application for RAW development and photo management. It covers the whole process: import and organise your photos, develop RAW files with non-destructive edits, and export finished images. It is often compared to Lightroom, minus the subscription.

Key Features

• Photo library with ratings, tags, and collections

How it works

The editor is deep, with modules for exposure, colour grading, sharpening, noise reduction, and local adjustments using masks. The library side adds ratings, tags, collections, and search, so you can manage a large archive without a separate catalog app. It runs on Windows, macOS, and Linux.

darktable is completely free under the GPL licence, with no paid tier and no locked features. The trade-off is a steep learning curve and a technical interface. For photographers who want a free, full-featured Lightroom alternative, it is the strongest open-source choice.
