## What it is
Hatch is a modern, extensible Python project manager from PyPA that combines a standards-compliant build system, environment management, Python version management, testing, static analysis, versioning, and publishing in one CLI. It is highly configurable via a pluggy-based plugin system and uses established Python standards (PEP 517/660, PEP 440, PEP 508) to avoid lock-in.

## Use cases
- manage python project environments and dependencies
- build and publish python packages to pypi
- scaffold new python projects from templates
- run tests across multiple python versions
- bump and manage project versions
- run python scripts with isolated dependencies
- replace setuptools with a modern pep 517 build backend

## When to choose
- you want a single tool covering build, environments, testing, and publishing for Python projects
- you need reproducible builds with a standards-based, plugin-extensible workflow
- you want fast environment creation with optional UV integration
- you are starting a new Python library or application and want best-practice defaults

## When to avoid
- your project depends on setuptools-specific legacy packaging features
- you need fully reproducible application lock files, which Hatch does not yet support
- your team is already standardized on another manager like Poetry or PDM and migration cost outweighs benefits
