Textual

A rapid application development framework for building sophisticated Terminal User Interfaces with Python.

Textual leverages Python to build rich terminal applications using CSS for layout and styling. It provides a robust event system and a library of ready-to-use widgets (like DataTables, TreeViews, and Input fields) that support mouse interaction and smooth animations. Built by the team behind Rich, it handles complex layouts through a reactive framework, allowing developers to create tools like the Frogmouth Markdown browser or the textual-paint editor with minimal boilerplate.
