## What it is
pipreqs is a Python CLI tool that generates a requirements.txt file by scanning a project's source code for imports and mapping them to PyPI package names. It supports custom PyPI servers, proxies, Jupyter notebook scanning, and version pinning schemes.

## Use cases
- generate requirements.txt from project imports
- find missing dependencies in a python project
- clean unused packages from requirements.txt
- compare requirements.txt against actual imports
- scan jupyter notebooks for dependencies

## When to choose
- you need a requirements.txt for a project that never had one
- you want imports-based dependency detection instead of environment snapshots
- you need to diff or clean an existing requirements file

## When to avoid
- you want to pin exact versions of an existing working environment (use pip freeze)
- you manage dependencies with modern tools like poetry or uv
- the project is unmaintained and you need active support

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: developer-tools, package-manager, parser
- domain: developer-tools
- platform: python, cli, cross-platform
- tags: requirements-txt, dependency-management, pip, static-analysis, command-line, automation
