Zypper is a command-line package manager (similar to APT for DEB-based systems or DNF for RPM-based ones) used in openSUSE, SUSE Linux Enterprise, and their derivatives. It provides users with a fast and flexible way to install, update, remove, and manage software packages and repositories, giving you full control over your system’s software environment.

Under the hood, Zypper works with RPM packages—the same package format used across many RPM-based Linux distributions. It relies on libzypp, a backend library that resolves dependencies, manages repositories, and handles transactions securely and efficiently.
