Meta Package Manager wraps all package managers with a unifying CLI, and provides the MPM CLI, a wrapper around all package managers. MPM is like yt-dlp, but for package managers instead of videos. MPM solves XKCD #1654 - Universal Install Script. List installed packages. List duplicate installed packages. Search for packages. Install a package, remove a package, and list outdated packages. Sync local package infos. Upgrade all outdated packages. Backup list of installed packages to TOML file. Restore/install list of packages from TOML files. Pin-point commands to a subset of package managers (include/exclude selectors). Support plain, versioned, and purl package specifiers. Export output to JSON or print user-friendly tables. Shell auto-completion for Bash, Zsh and Fish. Provides an Xbar/SwiftBar plugin for friendly macOS integration.
