## What it is
Corepack is a zero-dependency Node.js tool that manages and proxies Yarn, npm, and pnpm versions per project, so developers don't need to install package managers globally. It reads project configuration to download and run the correct package manager version automatically.

## Use cases
- use yarn and pnpm without installing them globally
- pin package manager versions per project
- ensure team members use the same package manager version
- prevent running the wrong package manager in a project
- manage package manager versions across many node projects

## When to choose
- you work across multiple Node.js projects using different package managers or versions
- you want reproducible package manager versions checked into your repo
- you want to avoid global yarn/pnpm installs

## When to avoid
- you only use npm and don't need version pinning
- you prefer managing package managers via a version manager like nvm or asdf
- you're on Node.js 25+ where Corepack is no longer bundled
