Adobe Lightroom is a commercial enterprise-class image editing software for professionals photographers.
Adobe has packed it with dozens of features that enhance photographer's workflow and improve their productivity.
Although it has an affordable paid subscription per month, you should consider open-source and free alternatives.
Therefore, in this article, we collected the best open-source and free alternative for Adobe Lightroom. However, you should consider certain limitations and different workflow if you are an avid Lightroom user.
Best Open-source alternatives for Adobe Lightroom
Darktable is a real open-source competitor for Adobe Lightroom, as it contains similar features and workflow. However, it may require some time to learn and use.
It offers non-destructive photo editing for raw and non-raw images, GPU accelerated image processing (which works seamlessly on my MacBook Pro Silicon M1), and a productive navigation system as well as colors management.
If you are a Lightroom user, certainly you will like DarkTable as it has a similar interface, navigation, a set of matching shortcuts that improve its usability.
But be aware, you may need to search for some tweaks to add a watermark and export settings and editing options.
The main reason why we add DarkTable on top of this list is: It has modules and a great automation system that makes photo editing ablaze.
darktable works on Linux, Windows, macOS (with M1 support).

PhotoFlow is available for Linux systems (Ubuntu, Arch Linux, Linux Mint), macOS as a DMG image, and offers a Windows 32-bit installer.

You may say it combines all options of Adobe Photoshop, Adobe Illustrator, and Houdini in one package.
The main reason why we added it to this list is its smooth workflow as well as its promising features.
Another unique feature for Graphite is that it is a web application that does not require desktop install and runs smoothly within all modern browsers.
The project is under continuous development and upgrades, so expect new features and improvements.

Hugin is a lightweight open-source panorama and photo stitching creator, it is not an Adobe Lightroom alternative, but we find it very useful for photographers, so we added it as an extra.
The first release of Hugin was released in May 2003, since then, the project has gained popularity among professional and semi-professional photographers.
Hugin is available for Linux (Ubuntu, Debian, Fedora, Linux Mint, Arch Linux, Manjaro), Windows, and macOS.
There are many Open-source Photography Workflow solutions and Adobe Lightroom alternatives. Most of them are rich in features and can be used directly with any project, or even customized to meet the special cases whenever needed.
Open source tools are no longer “secondary” tools that are only used when no budget is available to purchase premium ones, instead, they are taking over the entire proprietary software market, and becoming the default mainstream option, thanks for being full of features and being high-quality as we have seen in this list article.
If you have any additional software you would like to see in this list, then we would love to hear about them in the comments.
