Yes, Keka and The Unarchiver are other free options, but they don't support previewing the contents of the archive and dragging out only the things you want to extract.
I'm also going to be adding features to update the archive so you can just drag and drop new files into the archive in addition to renaming files and moving them around inside of the archive (and deleting files).
