Streamlit builds upon
three simple principles

Principle #1

Embrace scripting

Build an app in a few lines of code with our magically simple API. Then see it automatically update as you iteratively save the source file.

Principle #2

Weave in interaction

Adding a widget is the same as declaring a variable. No need to write a backend, define routes, handle HTTP requests, connect a frontend, write HTML, CSS, JavaScript, ...

Principle #3

Deploy instantly

Use Streamlit’s invite-only sharing feature to effortlessly share, manage, and collaborate on your apps.
