Worry not, because this guide showcases some popular free Adobe Lightroom alternatives!
RawTherapee
RawTherapee is a cross-platform raw image processing program. Rather than being a raster graphics editor such as Photoshop or GIMP or a digital asset management program like digiKam, it is specifically aimed at raw photo post-production. And it does it very well - at a minimum, RawTherapee is one of the most powerful raw processing programs available.

digiKam
digiKam is an advanced open-source digital photo management application on Linux, Windows, and MacOS. The application provides a comprehensive set of tools for importing, managing, editing, and sharing photos and raw files.
DigiKam's import capabilities can quickly transfer photos, raw files, and videos directly from your camera and external storage devices (SD cards, USB disks, etc.). The application allows you to configure import settings and rules that process and organize imported items on the fly.
digiKam organizes photos, raw files, and videos into albums. However, the application also features powerful tagging tools that allow you to assign tags, ratings, and labels to photos and raw files. You can then use filtering functionality to find items that match specific criteria quickly.
The application provides a comprehensive set of editing tools. This includes essential tools for adjusting colours, cropping, and sharpening and advanced tools for curve adjustment, panorama stitching, and much more. digiKam also has a unique tool based on the lensfun library that permits the automatic application of lens corrections to images.

LightZone
LightZone is professional-level digital darkroom software for Windows, Mac OS X, and Linux, including RAW processing and editing. Rather than using layers like other photo editors do, LightZone lets the user build up a stack of tools which can be rearranged, readjusted, turned off and on, and removed from the stack. It's a completely non-destructive editor, where tools can be readjusted or modified later - even in a different editing session. A tool stack can even be copied to a batch of photos simultaneously.

Photivo
Photivo is a free and open-source photo processor that handles RAW files and raster photos. Photivo tries to provide the best algorithms available, even if this implies some redundancy. It offers the most flexible and powerful denoise, sharpen and local contrast (fake HDR) algorithms in the open-source world.
Photivo is intended to be used in a workflow together with digiKam/F-Spot/Shotwell and Gimp. It needs a pretty strong computer and is not aimed at beginners.
