Is there an OSS option that comes close? Seems like the biggest hurdle is finding one that is close to reliable when authenticating with other sites (and able to adapt to changes they make, 2FA, etc.).
I guess the good news is that most of the ones I use are fairly popular/big (e.g. Vanguard, Ally, Schwab, etc.). But I have a couple loans (home, car) tied into smaller institutions.
EDIT: related, a recent thread on Mint alternatives that I had missed:
