Streamlit turns data scripts into shareable web apps in minutes. All in pure Python. No front‑end experience required.

Spinning up a `streamlit` app takes no time at all!

## _Speedrun_

<%= partial "/docs/languages-and-frameworks/partials/flyctl" %>

<%= partial "/docs/python/partials/speedrun", locals: { runtime: "streamlit", repo: "hello-streamlit" }  %>

## _Deploy a Streamlit from scratch_

<%= partial "/docs/python/partials/uv_init", locals: { runtime: "Streamlit" }  %>


Then we have to add the streamlit dependency:

```cmd
uv add streamlit
```

Now, let's create a simple streamlit app in `main.py`:

```python
import streamlit as st

st.write('hello from fly.io')
```

We can then serve the development version of the app using the `streamlit` cli tool:

```cmd
streamlit run main.py
```

This will display a 'hello from fly.io!' message when you visit the root URL.

Before deploying, we must add a bit of configuration to `.streamlit/config.toml`:

```toml
[server]
headless = true
```

This ensures that our app doesn't give a prompt when we ship it.
