## What it is
Brick is a declarative terminal user interface (TUI) programming toolkit for Haskell, built on top of the vty library. Applications are written as pure functions that render the UI from application state, plus event-handling functions that transform state.

## Use cases
- build a terminal user interface in Haskell
- write a TUI file manager or git client
- create interactive terminal apps with declarative layout
- build a terminal dashboard or game
- make a curses-style application without manual widget layout

## When to choose
- you are writing a Haskell program that needs a rich terminal UI
- you prefer declarative layout combinators over imperative widget setup
- you need cross-platform terminal support including Windows

## When to avoid
- you need a graphical (non-terminal) interface
- you are not working in Haskell
- you need a quick one-off script where a simple CLI suffices

## Facets
- artifact type: framework
- maturity: active
- function: terminal-ui, ui-components, gui
- domain: developer-tools, cross-platform
- platform: windows, cli, cross-platform
- tags: haskell, tui, vty, declarative-ui, command-line, linux, macos
