Jujutsu is essentially an alternative front-end or “porcelain” to git, both magnificiently simplified and powerful.
I tried it after using Emacs Magit for about six or seven years, and jujutsu is really easier to use than git and useful if one wants a tidy public history of changes (with “tidy” and “public” as Linus Torvalds recommends). Plus it is fully compatible to git as backend - other contributors will not even note you are using it.

Now, jujutsu covers almost the same with < 10% of that complexity and less than 10% of the documentation - simpler but the same power.
