git-absorb (https://github.com/tummychow/git-absorb) does a bit more, figuring out the exact changes that should be fixed up.

git-autofixup is better and easier to install: https://github.com/torbiak/git-autofixup

Could you elaborate how it is better?

[globular-toast]

They are quite different methods, explained by the respective implementations. IME autofixup finds the relevant commit successfully more often. There's no reason you can't use both, of course. I would always check the results of either before actually doing the rebase.
