## What is Textual?
Textual is a framework for building applications that run within your terminal. Text User Interfaces (TUIs) have a number of advantages over web and desktop apps.
Textual is a *Rapid Application Development* framework for Python, built by [Textualize.io](https://www.textualize.io).
Build sophisticated user interfaces with a simple Python API. Run your apps in the terminal and (*coming soon*) a web browser.
