🧹 pip-prune: The Python Dependency Cleaner That Will Save You Hours Every Week

pip-prune demo

Tired of bloated requirements.txt files? Meet pip-prune - the tool that automatically cleans your Python dependencies and saves you from dependency hell.

🚨 The Problem Every Python Developer Faces

You know the drill. You start a new Python project, install a few packages, and before you know it, your requirements.txt looks like this:

requests==2.31.0
numpy==1.24.0
pandas==2.0.0
matplotlib==3.7.0
typer==0.9.0
rich==13.0.0
# ... 50 more packages you installed "just in case"
Enter fullscreen mode Exit fullscreen mode

But here's the reality:

  • 🔴 80% of those packages are probably unused
  • 🔴 Your project takes forever to deploy
  • 🔴 Security vulnerabilities from unnecessary dependencies
  • 🔴 CI/CD builds are slow and expensive
  • 🔴 Docker images are bloated

Sound familiar? I built pip-prune to solve this exact problem.

✨ What is pip-prune?

pip-prune is a lightning-fast, zero-dependency Python CLI tool that:

  • 🔍 Scans your codebase using AST parsing to find actual imports
  • 🎯 Detects unused packages in your requirements.txt
  • 📌 Pins versions automatically for reproducible builds
  • 🚀 Optimizes your requirements.txt to the smallest possible set
  • 🎨 Beautiful terminal output with Rich library
  • ⚡ Runs in milliseconds - no network calls, pure Python

🚀 Installation & Quick Start 

# Install from PyPI
pip install pip-prune

# Scan your project
pip-prune scan --paths src/

# See what would be optimized (dry-run)
pip-prune rewrite --paths src/ --dry-run

# Actually optimize your requirements.txt
pip-prune rewrite --paths src/ --yes
Enter fullscreen mode Exit fullscreen mode

🎯 Real-World Example

Let's say you have this bloated requirements.txt:

requests==2.31.0
numpy==1.24.0
pandas==2.0.0
matplotlib==3.7.0
typer==0.9.0
rich==13.0.0
flask==2.3.0
django==4.2.0
fastapi==0.100.0
Enter fullscreen mode Exit fullscreen mode

But your code only uses requests and typer. Running pip-prune gives you:

requests==2.31.0
typer==0.9.0
Enter fullscreen mode Exit fullscreen mode

Result: 78% reduction in dependencies! 🎉

🛠️ Advanced Features

Runtime Tracing

Catch dynamic imports that static analysis misses:

pip-prune scan --paths src/ --trace "python main.py"
Enter fullscreen mode Exit fullscreen mode

Ignore Rules

Keep packages you want to preserve:

pip-prune rewrite --paths src/ --ignore numpy pandas
Enter fullscreen mode Exit fullscreen mode

Configuration Files

Use pyproject.toml or .pipprunerc.toml:

[tool.pip-prune]
paths = ["src", "tests"]
ignore = ["numpy", "pandas"]
tracer = false
Enter fullscreen mode Exit fullscreen mode

CI/CD Integration

Perfect for GitHub Actions:

- name: Check dependencies
  uses: Sherin-SEF-AI/pip-prune@v1
  with:
    paths: src/
Enter fullscreen mode Exit fullscreen mode
