## What it is
Copier is a Python library and CLI app for rendering project templates, supporting local paths and Git URLs with dynamic value substitution in any text file. It generates project scaffolds from configurable templates while avoiding overwriting existing files unless instructed.

## Use cases
- scaffold a new python project from a template
- create projects from git-hosted templates
- update an existing project when its template changes
- build reusable project templates with jinja2
- replace cookiecutter for project generation
- generate boilerplate files with interactive prompts

## When to choose
- you want template updates propagated into already-generated projects
- templates live in git repositories
- you need both a CLI and a Python library API
- you want fine-grained control over file overwriting and merging

## When to avoid
- you need a language-agnostic tool with a huge template ecosystem (cookiecutter has more templates)
- you only need simple static file copying without templating
- you cannot install Python 3.10+ and Git

## Facets
- artifact type: cli-tool
- maturity: active
- function: templating, cli, developer-tools, build-tool
- domain: developer-tools
- platform: python, cli, cross-platform, windows
- tags: project-scaffolding, project-templates, cookiecutter-alternative, jinja2, git-based-templates, command-line, automation, macos, linux
