Native Python CLI UI library with CSS-like styling

Casca

Casca is a lightweight, native Python TUI library with a DOM-like widget tree and CSS-style theming.

Features

• Zero core dependencies (standard library runtime)
• Declarative widgets (Container, Label, Input, Button, Card, Header, ScrollView)
• CSS-like style parsing and cascade
• Keyboard and mouse event handling in raw terminal mode
• Real examples including login screen, dashboard, and Groq chatbot

Quick Start

from casca import Container, Label, run_app

CSS = """
#root {
    padding: 1;
    border: ascii;
}
"""



ui_tree = Container(
    Label("Hello from Casca"),
    id="root",
)

if __name__ == "__main__":
    run_app(ui_tree, css=CSS)

Run Use Cases

python3 -m use_cases.login_screen
