About pyproject-hooks

from the package's own PyPI description — quoted content, verbatim

`pyproject-hooks`

This is a low-level library for calling build-backends in pyproject.toml-based project. It provides the basic functionality to help write tooling that generates distribution files from Python projects.

If you want a tool that builds Python packages, you'll want to use https://github.com/pypa/build instead. This is an underlying piece for pip, build and other "build frontends" use to call "build backends" within them.

You can read more in the documentation <https://pyproject-hooks.readthedocs.io/>_.

Note: The pep517 project has been replaced by this project (low level) and the build project (high level).

AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Provides low-level hooks to invoke build backends defined in pyproject.toml, enabling build frontends like pip and build to generate distribution files from Python projects.

Minimal friction: zero runtime dependencies, pure Python wheel, and active maintenance with recent releases. Last commit 2026-04-05 indicates ongoing project health.

MIT license (permissive) imposes no significant restrictions; you may use, modify, and distribute freely with minimal attribution requirements.

Usage

pip install pyproject-hooks==1.2.0

from pyproject_hooks import BackendProxy
backend = BackendProxy('.')
wheel_name = backend.build_wheel('dist')

Requires Python >=3.7; intended as a library for build tooling, not end-user software—direct usage is uncommon outside build frontends.

Verdict: A stable, well-maintained foundational library with no dependencies, permissive licensing, and zero known vulnerabilities. Suitable for build-tool integration; not a user-facing package. Install friction is negligible.

Needs verification

Whether BackendProxy is the primary entry point or if other APIs are equally important for typical use cases.
Performance characteristics or limits when calling multiple build backends in sequence.
