Nope, which honestly annoys me but is pretty par for the course. That said, when it comes to budgeting, I mostly care about where money is going and care less about the "whole financial picture." If I need to estimate what retirement looks like, I want more than a simple budgeting tool.

I personally use Fidelity for investment tracking. My main "checking" is their Cash Management Account, my "savings" is a brokerage account (invested in t-bills and money market funds), and I can link all of my other accounts and it pulls in specific investments and shows a consolidated view. It's awesome because it shows all kinds of stuff, like morningstar-style factor weights, sector exposure, etc. It's not self-hosted, but I trust them with my banking anyway, so it's not like I'm opening myself up to some new exploit (oh, and Fidelity also has proper MFA; Symantic VIP, which kinda sucks, but it's way better than any other financial institution).

I used to track this stuff via a Google spreadsheet (couldn't find a way to get stock quotes in LibreOffice), but this seems to be good enough for me.
