Welcome to Streamlit 👋

The fastest way to build and share data apps.

Streamlit lets you turn data scripts into sharable web apps in minutes, not weeks. It’s all Python, open-source, and free! And once you’ve created an app you can use our cloud platform to deploy, manage, and share your app!

Installation

pip install streamlit
streamlit hello

Streamlit can also be installed in a virtual environment on Windows, Mac, and Linux.

A little example

Streamlit makes it incredibly easy to build interactive apps:

import streamlit as st

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

A bigger example

Streamlit's simple and focused API lets you build incredibly rich and powerful tools. This demo project lets you browse the entire Udacity self-driving-car dataset and run inference in real-time using the YOLO object detection net.

The complete demo is implemented in less than 300 lines of Python. In fact, the app contains only 23 Streamlit calls which illustrates all the major building blocks of Streamlit. You can try it right now at share.streamlit.io/streamlit/demo-self-driving.

The Streamlit GitHub badge

Streamlit's GitHub badge helps others find and play with your Streamlit app.

Once you deploy your app, you can embed this badge right into your GitHub readme.md as follows:

Streamlit Cloud

Streamlit Cloud is our deployment solution for managing, sharing, and collaborating on your Streamlit apps.

The Teams and Enterprise tiers provide secure single-click deploy, authentication, web editing, versioning, and much more for your Streamlit apps. They're both currently in closed beta, and you can join the wait-list here.
The Community tier (formerly Streamlit sharing) is the perfect solution if your app is hosted in a public GitHub repo and you’d like anyone in the world to be able to access it. It's completely free to use and you can request your invite here.
