pkgview 0.5.2

CLI tool to list all installed programs and their package manager

pkgview

A CLI tool that lists all programs installed on your system and shows whether each one is managed by a package manager (brew, npm, pip, cargo, apt, snap, flatpak) or was installed manually — and therefore needs to be maintained by you.

Total: 75 programs  │  57 managed  │  18 manual

Features

• Detects programs from: brew, brew-cask, npm (global), pip, pipx, cargo, apt, snap, flatpak, conda / mamba / micromamba, pacman, dnf / yum, apk, nix, gem, composer, winget, scoop, chocolatey, nvm, asdf, pyenv
• Scans /Applications and ~/Applications on macOS for GUI apps
• Marks everything not tracked by a package manager as manual
• Correctly ignores macOS/Linux system binaries (/bin, /usr/bin, etc.)
• Correctly ignores Homebrew sub-binaries (e.g. dart from the flutter cask)
• All detectors run in parallel — fast even with many package managers installed
• Outputs a color-coded table or raw JSON (--json)
• Check for available updates with --outdated
• Export snapshots to JSON or CSV with --export

Requirements

• Python 3.9+ (already present on macOS and most Linux distros)
• No other runtime required

Installation

Recommended – install with pipx (no venv needed)

pipx installs CLI tools in an isolated environment automatically.

# Install pipx once (macOS)
brew install pipx
pipx ensurepath

# Install pkgview directly from GitHub
pipx install git+https://github.com/bini93/pkgview.git

The pkgview command is immediately available system-wide.

Update to the latest version:

pipx upgrade pkgview

Alternative – with pip (once published on PyPI)

pip install pkgview
# or
uv tool install pkgview

For development setup, project structure, and contribution guidelines, see DEVELOPMENT.md.

--json	-j	off	Output raw JSON instead of a table
--paths	-p	off	Add a Path column to the table
--outdated	-o	off	Check for available updates; highlight outdated packages in red
--export PATH	-e	–	Save snapshot to file (.csv → CSV, everything else → JSON)
--no-apps	–	off	Exclude GUI apps (/Applications)
--no-manual	–	off	Hide manually installed programs
--verbose	-v	off	Show each detector's name, package count, and elapsed time
--version	-V	–	Show version and exit

Examples

# List everything, sorted by manager (default)
pkgview

# Show only manually installed programs (needs attention)
pkgview --filter manual

# Show only Homebrew formulas, sorted by name
pkgview --filter brew --sort name

# Show with full paths
pkgview --paths

# Export as JSON (e.g. for backups or scripting)
pkgview --json > programs.json

# Hide noise: no system apps, no manual tools
pkgview --no-apps --no-manual

Roadmap

• pkgview --outdated — highlight packages with available updates
• pkgview --export — save snapshot as JSON/CSV for system backups
• nvm / asdf / pyenv detector
• Windows support (winget, scoop, chocolatey)
• conda / mamba detector
• pacman / dnf / apk / nix / gem / composer detectors
• TUI mode with Textual (pkgview --tui)
• Docker Desktop, VS Code extension detection
• Publish to PyPI — pipx install pkgview without GitHub URL
• Homebrew Tap — brew install yourname/tap/pkgview
