Hello! We do not currently have a list available online as the banks are being updated quite frequently. However, you can download the free version of MoneyWiz and browse the list at no cost. Tip: you can display all banks from a particular country by using the country code (i.e. searching for "PL" without the quotes will give you the list of banks from Poland).
Trying to connect to one of the banks though will require a subscription (or a trial): https://wiz.money/buy/
