I’ve never used Calibre-web so I wouldn’t know the difference but Calibre Web Automated is supposed to be a blend of Calibre and Calibre-Web. I don’t run a calibre server at home anymore because it wasn’t needed after implementing CWA. I did have to copy some Calibre files to run the CWA container (it’s in the setup doc) but I haven’t needed Calibre since setting up CWA. Whenever I get more books I move the files to the “booksync” folder and it uploads it to CWA. You can also upload them via the webpage. The downside, I usually have to manually fetch the metadata for the books. But that’s not a big deal to me. At least I can do everything in one place. I think CWA supports CW plugins, but I’m not 100% certain. I would recommend it if you’re looking for one place to hold and update your books metadata.
