The devs are also pretty responsive to bug reports!
I will say that they themselves have mentioned that there is kind of a limit in library size because the project is meant to serve "small to modest personal libraries" but I think it was ranked as a few thousand, so that won't be a problem for most people I think.
I believe the numbers I saw were about 3-5k, so it might not handle your collection well. However, I encourage you to check their github to confirm rather than just go off my vague recollection alone.
