What does it do?
Rich takes the terminal, that intimidating black window with white text, and lets developers fill it with color, tables, progress bars, syntax-highlighted code, and even rendered markdown. Picture upgrading from a typewriter to a full desktop publishing program, except it’s for command-line output instead of paper. A developer writes a couple of lines, and Rich handles laying out a properly aligned table or a smoothly updating progress bar across different terminal widths and operating systems. It’s become something of a design language for how modern Python tools present themselves to users.
See it in action
This prints a neatly formatted, colorful table listing a movie’s release year and title to the terminal.
from rich.console import Console
from rich.table import Table
console = Console()
table = Table(title="Star Wars Movies")
table.add_column("Released")
table.add_column("Title")
table.add_row("1977", "A New Hope")
console.print(table)Why would a non-developer care?
If you’ve ever run a Python tool and been surprised that its output looked genuinely nice, organized, colorful, readable, instead of a wall of gray text, there’s a good chance Rich was behind it, and that polish changes how trustworthy and professional a tool feels.
Real-world examples
Rich powers the visual style of countless open-source command-line utilities that want to look modern, and its creator, Will McGugan, later built an entire terminal application framework, Textual, directly on top of it. Without libraries like this, most command-line tools default to the same flat, monochrome text output that hasn’t changed since the 1980s.
Who uses it
Developers building command-line tools and scripts who want clear, attractive output instead of plain scrolling text.
How it compares to alternatives
It goes far beyond older, narrower tools like colorama, which only adds color, by covering tables, progress bars, tracebacks, and markdown rendering in one package; it’s now the foundation for the more ambitious Textual framework.
Fun fact
Rich can render itself inside Jupyter notebooks too, not just terminals, so the same formatting code works in both places.
