## What it is
Mordant is a Kotlin multiplatform library for rendering styled text in the terminal, including ANSI colors, tables, panels, markdown rendering, and widget animations. It automatically detects terminal capabilities and is distributed via Maven Central.

## Use cases
- add colored ANSI output to a Kotlin CLI app
- render tables and panels in the terminal
- show progress bars and animated dashboards in a console app
- render markdown directly in the terminal
- style terminal text with automatic capability detection

## When to choose
- you're building a Kotlin or Kotlin Multiplatform command-line application that needs styled output
- you want terminal widgets like tables, lists, and progress bars with animation support
- you need markdown rendering in a console interface

## When to avoid
- you need a full TUI framework with keyboard input handling and complex layouts
- your project is not on the JVM/Kotlin ecosystem
- you only need simple ANSI color codes in a non-Kotlin language

## Facets
- artifact type: library
- maturity: active
- function: terminal-ui, developer-tools, markdown, animation
- domain: developer-tools, cross-platform
- platform: jvm, cli, cross-platform
- tags: ansi-colors, text-styling, progress-bars, tables, kotlin-multiplatform, command-line
