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
