UniGetUI is a cross-platform package manager GUI that provides a unified interface for multiple package managers (WinGet, Chocolatey, Scoop, Homebrew, Snap, Flatpak, APT, DNF, Pacman, pip, npm, Bun, .NET Tool, etc.). The application follows a clean layered architecture with Avalonia-based MVVM UI, a domain package engine, and infrastructure services for settings, logging, telemetry, and IPC. It supports both GUI and headless/daemon modes for automation, includes operation history tracking, secure settings storage, package bundling, and scheduled maintenance tasks. The codebase demonstrates strong engineering practices with clear separation of concerns, extensive test coverage, and modern .NET patterns.
Scoop is a command-line installer for Windows that manages application installation, updates, and dependencies through JSON manifests. It uses a modular PowerShell architecture with core libraries (lib/) handling manifest parsing, dependency resolution, downloading, and installation, while command-specific scripts (libexec/) implement user-facing operations like scoop-install and scoop-update. The system creates shims for PATH isolation, supports automatic updates via checkver/autoupdate, and maintains a SQLite cache for performance. External dependencies include PowerShell, 7zip, aria2, and Git for bucket management.
