I use a product called Lightzone, it is opensource and it is Lightroom like. I used Lightroom for years, but I don't make any money at this, I just take a lot of photos in the mountains. I am hoping to add drone photos and video to that. I have been using Lightzone since I found it as a alternative to Lightroom. I am not pushing it, it has an interface like Lightroom so the transition is not hard. When you do a google or bing search is it is one of the first links for me. Then I do a lot of they type of searching the site is lightzoneproject.org. Hope that helps.
