Poetry helps you declare, manage and install dependencies of Python projects, ensuring you have the right stack everywhere.

Poetry Install (image)

Poetry replaces setup.py, requirements.txt, setup.cfg, MANIFEST.in and Pipfile with a simple pyproject.toml based project format.

```toml [build-system] requires = ["poetry-core>=2.0.0,<3.0.0"] build-backend = "poetry.core.masonry.api"

[project] name = "my-package" version =...

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

Poetry is a dependency management and packaging tool that replaces setup.py, requirements.txt, and Pipfile with a unified pyproject.toml-based workflow for declaring, locking, and installing Python project dependencies.

Low friction installation with a pure-wheel distribution. Active maintenance (96 days since last release) and 22 runtime dependencies including build, virtualenv, requests, and keyring suggest a mature, production-grade tool.

MIT license permits unrestricted use, modification, and distribution in both open-source and commercial contexts with minimal obligations—a permissive choice typical of widely-adopted developer tools.

Usage

pip install poetry==2.4.1
poetry --version
poetry new my-project
cd my-project
poetry add requests

Requires Python >=3.10,<4.0; poetry-core>=2.0.0,<3.0.0 is a build-time dependency for projects using Poetry as their build backend.

Verdict: Poetry is a mature, actively maintained dependency-management tool with no known vulnerabilities and permissive MIT licensing. Its 22 runtime dependencies reflect comprehensive feature coverage (virtual environments, keyring integration, git support via dulwich, HTTP requests). Suitable for production use.

Needs verification

Community adoption scale and real-world usage patterns beyond the top_1000 popularity tier classification.
Performance characteristics when managing very large dependency graphs or monorepo structures.
Compatibility with non-standard Python distributions (PyPy, Conda, etc.) beyond CPython 3.10–3.14.
