## What it is
mpb is a Go library for rendering multiple progress bars in terminal CLI applications. It supports dynamic add/remove of bars, dynamic totals, cancellation, and decorators like ETA, percentage, and byte counters.

## Use cases
- show progress bars for concurrent downloads in a Go CLI
- render multiple progress bars in a terminal app
- display ETA and percentage while processing files
- track progress of parallel worker goroutines
- add spinners and byte counters to a command-line tool
- dynamically add and remove progress bars at runtime

## When to choose
- you are building a Go CLI that needs rich terminal progress output
- you need multiple simultaneous progress bars with synchronized widths
- you want ETA, percentage, or byte-count decorators out of the box

## When to avoid
- you need a GUI or web-based progress display
- your project is not written in Go
- you only need a simple single-line spinner with no dependencies

## Facets
- artifact type: library
- maturity: active
- function: cli, terminal-ui, developer-tools
- domain: developer-tools, cross-platform
- platform: go, cli, cross-platform
- tags: progress-bar, spinner, terminal-ui, go-library, actor-model, command-line
