I find Google Sheets pretty hard to beat - you can get stock pricing data via the GOOGLEFINANCE function, and I have a simple script that does imap -> sheets for bank and credit card balances. I'm able to keep an up to date view of my net worth without resorting to Mint/Plaid et al. And you can generate whatever charts and graphs you like fairly easily - have access on your phone, etc.

For budgeting, I import csv from my bank/credit cards into google sheets and tag transactions with ~20 different categories - I do this every month or two and it doesn't take that long. It gives me a backwards view of my spending that I can use to influence future spending. I don't run a hard budget really.
