which banks offer free instant external transfers?

I just realized that my US Bank account has it, but in every other sense I have had a miserable experience with them. I also refuse to use a fee-riddled major brick and mortar bank my main. Only other thing I like is their credit cards. that said, I would like to know if there are any better banks with that feature.

Paypal gives instant transfers but they charge a fee. Cap1 and wells don’t offer it I know.

Edit: thanks for the downvote brigade in the comments. Incredibly helpful to downvote anyone even daring to ask if something is available. Also thanks for implying that I'm doing something illegal by simply asking if there are more institutions that offer free and instant bank to bank transfers.
