Selfhosted alternatives to Goodreads?

So I finally broke down and made a very poor purchasing decision and ordered an e-ink writer to be a notepad/e-reader hybrid. Partially so that it is less of a hassle to read books I got from kickstarters and the like while still using the kindle app for the disturbing amounts of money I throw at Amazon.

Historically? I loved goodreads because theoretically I would get good recommendations based on what I liked. In practice, that has never happened but it is still nice to see if I read something in the past. And once I have multiple ebook ecosystems, it will be nice to actually check that rather than spend the first 100 pages wondering if this is familiar.

So any good recommendations? I suspect what I SHOULD do (and will likely start doing more as a self betterment thing) is just put a note in my personal nextcloud every time I finish a book with a quick summary and some thoughts. But having the big database is also really nice.

Thanks
