Py.cafe is a platform that allows you to create, run, edit, and share Python applications directly in your browser. There's
no need for any installation; it works with just a single click.
            
And now, you can use Streamlit on py.cafe! Streamlit is a popular Python library for creating web applications with simple

### Useful links:
            
* [Streamlit official website](https://streamlit.io/)
* [Streamlit documentation](https://docs.streamlit.io/)

### Alternatives
            
Also take a look at [stlite](https://edit.share.stlite.net/), a similar platform that allows you to create, run, edit, and share Python applications directly in your browser.
            
Py.cafe runs an unmodified version of streamlit, compared to stlite which has some modifications to make it work in the browser.
