pCloud is a Swiss based cloud storage option that has native Windows, Mac, and Linux options along with mobile apps. It has a React and Javascript API available. I’ve been testing it out on Artix Linux for a little while now and it’s been a pretty solid replacement for OneDrive and Dropbox for me. It also has some privacy policies I can get behind since I am a bit security minded.
