Nox

Nox is a command-line tool that automates development tasks like testing and linting across multiple Python environments. It utilizes a standard Python file (`noxfile.py`) for configuration, creating isolated virtual environments for each defined session. This approach provides programmatic control and reproducibility, installing specified dependencies and running commands within each isolated environment. As of version 2026.2.9, Nox is actively maintained with a regular release cadence, often following a calendar versioning scheme.
