## What it is
Stack is a cross-platform build tool and package manager for developing Haskell projects. It manages GHC toolchains, dependencies via Stackage snapshots, and provides reproducible builds for new and experienced Haskell users.

## Use cases
- build haskell projects
- manage ghc compiler versions
- install haskell packages
- reproducible haskell builds
- set up a haskell development environment
- create a new haskell project scaffold

## When to choose
- you want reproducible Haskell builds with curated Stackage snapshots
- you need automatic GHC toolchain installation across Linux, macOS, and Windows
- you are new to Haskell and want a batteries-included workflow

## When to avoid
- your project or team standardizes on Cabal-only workflows
- you need fine-grained control over dependency resolution outside Stackage snapshots

## Facets
- artifact type: cli-tool
- maturity: stable
- function: build-tool, package-manager, developer-tools, cli
- domain: developer-tools, programming-languages
- platform: windows, cli
- tags: haskell, stackage, reproducible-builds, ghc-toolchain, command-line, linux, macos
