zypper remove --clean-deps removes automatically installed requirements when removing a package. zypper packages --unneeded will show a list of packages no longer required.

Setting solver.onlyRequires to true in /etc/zypp.conf does not install recommends - it's way less of a problem than on Debian/Ubuntu due to not recommending half the world, but still useful. Setting solver.cleandepsOnRemove will automatically remove automatically installed deps when removing a package (i.e., like always specifying --clean-deps).

If you don't know the zypper commands just go into the GUI Yast Software tool, click on the various heading drop downs.

Under Options drop-down you can check the option "Cleanup when deleting packages"

Under View filter you can select Uneeded Packages, click to uncheck the boxes of what shows up and Apply.

Also these are handy sheets.

Simple. Run sudo apt autoremove and pretend like it worked. You'll never know if it did or not. Like and subscribe

sudo zypper packages --unneded will give you a list of packages that have not been explicitly requested and are not dependencies of explicitly requested packages. As for how to remove them... IDK (I do it manually, once in a blue moon: it's not like there's new unneded packages every week).

It's been a while since I've used debian, but IIRC apt autoremove will leave behind config files (unless you specify --purge).

In tumbleweed (and I think all rpm-based distros?) config files are removed per default together with packages (well, the config files installed with the package, not others that may have been created later such as the ones in your \~ - basically zypper rm is the same as apt purge).

I've been using opensuse for years and not found a solution to this. I have a new appreciation for apt and my next OS will definitely be debian-based.
