Chalk
The most popular Node.js library for styling terminal string output with ANSI colors.
xterm.js
A fast, self-contained TypeScript library for embedding fully-featured terminals in the browser.

An extremely fast Python linter and code formatter, written in Rust, built as a drop-in replacement for Flake8, Black, isort, and dozens of plugins.
ora
An elegant, dependency-light terminal spinner for Node.js command-line apps and scripts.
tqdm
A fast, extensible progress bar for Python loops and CLI pipelines, with negligible overhead.

picocolors
The tiniest, fastest zero-dependency library for ANSI terminal color formatting in Node.js.
Collision
Beautiful command-line error reporting for PHP apps and test suites
sentry-cli
Official command-line tool for uploading source maps, debug symbols, and managing releases and deploys in Sentry.

Rspack CLI
The official command-line interface for running Rspack builds, dev servers, and previews.
Ratatui
Rust library for building rich terminal user interfaces and dashboards
Symfony Console
The PHP framework component for building beautiful, testable command-line applications
console
A Rust library for terminal and console abstraction: colors, styles, cursor control, and terminal size detection
portable-pty
Cross-platform Rust API for pseudo-terminals, with runtime-selectable implementations
quicktype
Generate strongly-typed models and serializers from JSON, Schema, TypeScript, or GraphQL

A Rust library for building interactive command-line prompts — text, select, multiselect, confirm, date, and password inputs with validation, autocompletion, and theming.
termenv
Advanced ANSI color and style support for Go terminal apps, with automatic terminal-capability detection and safe degradation.
