>Is darktable a free Lightroom alternative?¶ Yes and no. Darktable is an alternative to Lightroom the same way any other raw editor is, since it edits raw files, but it would be a mistake to think it’s a direct replacement. Other than both being raw editors with photo library management, and looking somewhat similar, they have very little in common.
What they mean is, Darktable has very capable editing functionality, but its "library management" is such an afterthought that I would challenge whether it even deserves to be called library management. It seems to be oriented around the design philosophy that photographers should be organizing their library with CLI tools.
But yes, the library features could do with some improvements.
I had folders based on dates YYYY.MM.DD - Eventname. No need for cli.
I still do the same now for CaptureOne to be honest.
"If you give up on these features, it's a replacement" doesn't make it a replacement.
People often use other software as replacement for establishes software, even though not every single feature is available. I still would say Firefox can be a chrome replacement.
My images are also stored in date-based folders, but C1/Lightroom allow me to very quickly move between folders and identify the file I want, search for files I've rated highly or tagged with keywords/colors, and more.
OpenCL is unsupported for M1/2/3/4/5, which makes RAW file processing, batch workflows, basically everything, unusably slow.
Unless something has changed in the past few months, Darktable is dead on MacOS with no fix in sight.
