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.

MyApp.py

import streamlit as st
import pandas as pd
st.write("""
# My first app
Hello *world!*
""")
df = pd.read_csv("my_data.csv")
st.line_chart(df)

My first app

Hello world!

Deploy instantly

The choice is yours — show off your public apps for free on Streamlit Community Cloud, go with Snowflake for enterprise‑grade deployment, or pick something else entirely!
