Actualbudget.com =/= actualbudget.org

Originally the project was a closed source budgeting app to compete against YNAB on privacy and cost but the developer got overwhelmed and decided to open source the project.

I can’t remember all the details why the project doesn’t have access to the .com domain still, but you can use the .org site to see the details/source code. (You can also see the .com address hasn’t been updated, and still has the original 2020 copyright date)
