Yep! for a while I deployed Calibre-Web alongside Calibre in a ‘books’ compose.yaml stack using Docker. I used volume mounts to expose my library to both containers. The main thing to be cautious of is that you don’t write to the db from both C and CW at the same time (which could result in corruption). Some folks spin up/down Calibre as-needed, but I had them both running and was just mindful. I personally ended up switching from C+CW to Calibre-Web Automated and fully removing Calibre. I’m able to do everything from CWA that I was doing in both previously. FWIW if you are managing devices (e.g., family, etc.), Kobo devices + Kobo sync via CW/CWA is wonderful for usability (books show up on devices ‘natively’).

I use shelfmark (link: https://github.com/calibrain/shelfmark) with my hardcover API for metadata, connects seamlessly with calibre-web-automated (link: https://github.com/crocodilestick/Calibre-Web-Automated) for imports, etc.
