## What it is
Terminal.Gui is a cross-platform terminal UI (TUI) toolkit for .NET that lets developers build sophisticated console applications with rich interfaces. It provides 50+ built-in views including text editors, tables, tree views, menus, charts, and file dialogs, with keyboard-first and mouse-driven interaction, TrueColor, Unicode support, and double-buffered rendering.

## Use cases
- build a full-screen terminal dashboard with tables and charts in C#
- create a console app with menus, forms, and wizards
- make an in-line CLI tool with a rich UI like Claude Code or Codex CLI
- add a text editor with undo/redo and clipboard to a terminal app
- build a cross-platform file browser for the terminal
- write an interactive TUI installer or configuration wizard

## When to choose
- you are building .NET/C# console applications that need rich interactive UIs
- you need consistent TUI behavior across Windows, macOS, and Linux
- you want keyboard-first UX with full mouse support, TrueColor, and Unicode
- you need scalable tables or tree views for large datasets in the terminal

## When to avoid
- you are building a web, desktop GUI, or mobile application
- your project is not on the .NET platform
- you only need simple line-based console output or basic CLI argument parsing
- you need a TUI toolkit in another language like Rust or Go
