🚀 PyLite Manager

Python Virtual Environment & Package Manager GUI

Manage Python installations, virtual environments, and pip packages — all from a clean desktop GUI.

No more terminal juggling.

✨ What is PyLite Manager?

PyLite Manager is a lightweight desktop application that helps you:

• Manage Python installations
• Handle virtual environments (venv)
• Install, update, and remove pip packages

All through an intuitive Tkinter-based GUI, without relying on the terminal.

Perfect for developers who want a visual Python environment manager instead of CLI-heavy workflows.

🏗 Architecture

We've organized the application to separate UI components from core processing safely. It relies entirely on standard libraries for security and lightweight deployment.

3. Manage Packages: Select an environment, and seamlessly update or search packages on the right panel.
4. Check Stats: Click Stats for package count and version distribution insights.
5. Export/Import Requirements: Snapshot or restore environment state using requirements.txt.
6. Backup/Clone Venvs: Right-click an environment to backup or clone it.
7. Set Defaults: (Windows only) Set your desired global Python version effortlessly.

🛠 Troubleshooting

tkinter not found?

Ensure you have the tkinter module installed.

• Ubuntu/Debian: sudo apt install python3-tk
• Fedora: sudo dnf install python3-tkinter
• macOS: brew install python-tk

Environments taking long to load?

Try refining your scan directories to deeper levels to prevent scanning extensive root system drives. Background processes keep the UI responsive, but minimizing search depth is always faster.
