What Is Streamlit?—An Intro for Beginners

Streamlit is a tool that makes building web apps incredibly straightforward, especially for AI engineers. Imagine we have all these complex retrievers and generators that we want to share with the world, but we don’t want to get bogged down in the nitty-gritty of web development. That's where Streamlit comes in.

Here's how it works, in plain terms. We write a Python script just like we would for any other project. However, instead of writing code that just runs and gives us an output in the terminal, we write code that generates an interactive web app. Streamlit watches our script and automatically creates the web app as we write it. We don’t need to know HTML, CSS, or JavaScript. We don’t need to set up a server or worry about the frontend. Streamlit takes care of all that for us.
