To clarify for others though as I guess I wasn’t clear based on the downvotes : I’m not suggesting a single piece of software is a viable alternative to Lightroom. Rather I’m saying Lightroom itself is a collection of algorithms dedicated to photo editing wrapped in a UX one is familiar with. On the other hand ImageMagick (just to pick one I know relatively well) is a set of command line tools for image editing. It’s mostly used as a backend with other tools as interface. I imagine there are plenty of alternatives to ImageMagick too, probably some that can include arXiv STOA algorithms for photo editing, maybe some even with a GUI but my point again is to reconsider the workflow to understand how the tools one rely on actual work.
So to hopefully express myself better this time, ImageMagick + Gimp + Krita + some script in a Github repository based on an arXiv publication + I don’t know what + … all together or in part might be better for some people but no I don’t know an all-in-one open source alternative that cover ALL needs without them being expressed first.
Nothing you (nor I) know of but that doesn’t mean it’s the case. I can’t evaluate but https://www.openimagedenoise.org/ is publishing by Intel and in 2026 so maybe it’s good.
No photo editing software even comes close to lightroom. As I said in the OP I’m simply not interested in alternatives.
Right, then I can’t help you.

Nothing offers the AI tools that adobe does. AI denoise is an irreplaceable feature for me.
