Been using https://www.budgetwithbuckets.com/ for a few years now, isnt updated very often and is still missing a standalone android app, but other than that fairly similar to YNABs pre-subscription. It also supports various kinds of data importing and importing exports from YNAB.

If only I could remind myself to actually fill it in more often.
