## What it is
pip-tools is a set of command line tools (pip-compile and pip-sync) for keeping pinned Python dependencies fresh and deterministic. It compiles requirements files from pyproject.toml, setup.cfg, setup.py, or requirements.in and syncs environments to match.

## Use cases
- generate a fully pinned requirements.txt with hashes from pyproject.toml
- lock Python dependencies for reproducible production builds
- sync a virtualenv to exactly match a requirements file
- upgrade pinned dependencies in a controlled way
- manage transitive dependency resolution for a Python app

## When to choose
- you use pip-based workflows and need deterministic, pinned dependency sets
- you want lockfile-style reproducibility without leaving pip
- your project uses pyproject.toml, setup.cfg, or setup.py for dependencies

## When to avoid
- you already use a modern lockfile tool like uv, Poetry, or PDM
- you need dependency management for non-Python ecosystems

## Facets

- domain: developer-tools
