Vim supports an undofile, to keep undo history persistently. https://jovicailic.org/2017/04/vim-persistent-undo/

IntelliJ has a feature called "Local History" which stores basically is storing undo history, but it stores other things too (like test execution).

A git repository would suffice, just commit throughout the project as normal.
