Welcome to Streamlit 👋

A faster way to build and share data apps.

What is Streamlit?

Streamlit lets you transform Python scripts into interactive web apps in minutes, instead of weeks. Build dashboards, generate reports, or create chat apps. Once you’ve created an app, you can use our Community Cloud platform to deploy, manage, and share your app.

Why choose Streamlit?

  • Simple and Pythonic: Write beautiful, easy-to-read code.
  • Fast, interactive prototyping: Let others interact with your data and provide feedback quickly.
  • Live editing: See your app update instantly as you edit your script.
  • Open-source and free: Join a vibrant community and contribute to Streamlit's future.

Installation

Open a terminal and run:

$ pip install streamlit
$ streamlit hello

If this opens our sweet Streamlit Hello app in your browser, you're all set! If not, head over to our docs for specific installs.

The app features a bunch of examples of what you can do with Streamlit. Jump to the quickstart section to understand how that all works.

Quickstart

A little example

Create a new file named streamlit_app.py in your project directory with the following code:

import streamlit as st

x = st.slider("Select a value")
st.write(x, "squared is", x * x)

Now run it to open the app!

$ streamlit run streamlit_app.py

Give me more!

Streamlit comes in with a ton of additional powerful elements to spice up your data apps and delight your viewers. Some examples:

Our vibrant creators community also extends Streamlit capabilities using  🧩 Streamlit Components.
