The best alternative to Adobe Photoshop Lightroom Classic is darktable, which is both free and Open Source. If that doesn't suit you, our users have ranked more than 50 alternatives to Adobe Photoshop Lightroom Classic and many of them are so hopefully you can find a suitable replacement. Other interesting alternatives to Adobe Photoshop Lightroom Classic are digiKam, XnView MP, Hugin and Photon Studio.

Works better than Lightroom when your photos are on a NAS
digiKam is an advanced digital photo management tool that simplifies importing and organizing photos into albums. It supports various formats including RAW, features tagging, metadata management, duplicate finder, photo editing, sharing, GPS data handling, and has cross-platform compatibility.
Comprehensive photo management software for viewing, batch converting, editing and resizing images and creating thumbnail sheets.
XnViewMP sure is a fine piece of software, and is in fact my default image viewer. But its editing and sorting capabilities are not as powerful and practical as Lightroom.
With Hugin you can assemble a mosaic of photographs into a complete immersive panorama, stitch any series of overlapping pictures and much more.

I have experience using both darktable and Lightroom Classic. In my estimation, darktable is a more powerful tool than Lightroom Classic, except for the new AI features that LR has. However, darktable can be somewhat more cumbersome for novice and casual users.
