Textual TUI Framework

Build terminal applications with Textual's web-inspired architecture: App → Screen → Widget.

Quick Start

from textual.app import App, ComposeResult
from textual.widgets import Header, Footer, Static

class MyApp(App):
    CSS_PATH = "styles.tcss"
    BINDINGS = [("q", "quit", "Quit"), ("d", "toggle_dark", "Dark Mode")]

    def compose(self) -> ComposeResult:
        yield Header()
        yield Static("Hello, World!")
        yield Footer()
