Hatch is a versatile and modern Python project manager that facilitates the creation and management of multiple virtual environments for a single Python application, addressing the challenges of varied dependency requirements across different Python versions and stages of development. Unlike traditional tools such as venv, conda, or tox, Hatch dynamically downloads necessary Python distributions and offers more configurability and extensibility through its build backend, Hatchling. It simplifies development workflows by allowing the definition of dependencies and execution of scripts within isolated environments, which are specified in the pyproject.toml file. Despite its advantages, Hatch faces limitations in handling system-level dependencies and interfacing with compilers, issues that can be mitigated by using Earthly to manage both Python and system-level dependencies within a single Earthfile. This integration helps streamline development processes and ensure consistency across diverse systems, although Hatch remains limited in managing non-Python dependencies and patch release versions.
