Streamlit builds upon three simple principles

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.
  • import streamlit as st
  • import pandas as pd
  • ย 
  • st.write("""
  • # My first app
  • Hello *world!*
  • """)
  • ย 
  • df = pd.read_csv("my_data.csv")
  • st.line_chart(df)
My App โ€ข Streamlit

My first app

Hello world!

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, ...

Deploy instantly

Effortlessly share, manage and deploy your apps, directly from Streamlit. All for free!
