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

Manages application settings and configuration using Pydantic models, with support for loading from environment variables, .env files, and other sources through python-dotenv integration.

Low install friction with a pure-wheel distribution and only three runtime dependencies (pydantic, python-dotenv, typing-inspection). Actively maintained with a release 6 days old and continuous CI/CD signals.

MIT license permits unrestricted use, modification, and distribution in both open-source and commercial projects with minimal obligations.

Usage

pip install pydantic-settings

from pydantic_settings import BaseSettings

class Settings(BaseSettings):
    api_key: str
    debug: bool = False

settings = Settings()

Requires Python 3.10 or later; pydantic must be installed as a runtime dependency.

Verdict: Production-ready settings library with active maintenance, no known vulnerabilities, permissive MIT licensing, and minimal dependencies. Top-100 PyPI package backed by the Pydantic team with strong CI coverage and broad Python version support (3.10–3.14).
