Language: PythonRuntime: Python 3.8+WebsiteSource

Textual by Textualize is a Python TUI framework that brings CSS-like styling to the terminal. It features a rich widget library (buttons, trees, tabs, data tables, markdown viewers), reactive data binding, and the ability to serve TUIs as web apps via Textual Web.

Textual requires the Modern TUI baseline — truecolor for its CSS color system, mouse tracking for interactive widgets, and bracketed paste for text input. It also benefits from Rich features like hyperlinks when available.
