I didn't even use the budgeting/bells and whistles features. It was mostly a great way to download transactions in a unified format from a dozen different banks past their short retention periods. I hope something similar exists :-(
Lotta trust required there, though. That cred DB gets compromised and that's your entire financial life
For me the risk was acceptable because it was read-only access from a very small number of institutions. But those institutions have changed over the 15 years I used Mint, so having the historical data from places I used to have accounts was immensely helpful in understanding things like how much net worth changed over time. Especially when I could layer in other accounts manually as well as estimated real estate values from Zillow. So "I bought a house" wouldn't show up as "I lost $X dollars" but instead "I owe $X on a mortgage against a house worth $Y."
