So way back when I used to use Mint.com to help me manage my finances. It worked great until Intuit bought them, ended the app, and redirected their customers to CreditKarma. I hated getting spam messages and haven’t used a personal finance app for years. I finally set up ActualBudget and it great for budgeting but I want to keep track of investments, retirement holdings, property, and things outside of the monthly budget. I don’t think ActualBudget does that. Are there any self hosted projects that helps me keep track of stocks, property, and other assets?
I think this probably still won’t do what you want, but actual-helpers has a script that will track the balance of an investment account. It won’t track shares or funds separately or anything, but it could maybe be enough if your goal is just net worth tracking?
