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?
GnuCash will do the sort of security trade accounting you’re talking about. I don’t know how GnuCash compares to the other offerings, but it can be fully offline and has a lot of features.
