I mostly use the envelope method. My parents used literal envelopes when I was growing up, and somewhat early in my adulthood and in my career I came upon the online bank Simple. That bank changed the way I look at finances and saving money. So I still do it the way they taught me to do it.
I now use a bank called Monzo, and they are working toward building in a very similar budgeting method to Simple, with "Pots" instead of envelopes, that automatically get filled with money every paycheck.
How in the fuck...
