Streamlit vs Gradio: Choosing the Right Tool for Building Generative AI Apps

📘 Introduction

Choosing the right framework can dramatically shape the experience of building and deploying generative AI applications. Streamlit and Gradio are two of the most popular tools for rapidly creating AI demos, prototypes, and interactive interfaces — but they shine in different scenarios.
In this guide, we’ll break down when to use each, their ideal use cases, and the key differences that matter when building GenAI apps. 🚀

🐍🔴 When to Use Streamlit

Streamlit is designed for creating data-rich, interactive Python apps with minimal complexity. It's an excellent choice for AI developers who want clean layouts, polished UI components, and full control over app logic — all within Python.

You might choose Streamlit if you want to:
✅ Build AI dashboards, analytics tools, or monitoring interfaces
✅ Prototype generative models with custom layouts
✅ Integrate multiple components (inputs, charts, text, images, complex workflows)
✅ Deploy internal tools or production-grade AI apps
✅ Have full control over app structure and page navigation

Streamlit gives you a fast development experience while still feeling flexible and powerful. If you want a more "app-like" experience for users, Streamlit is often the better fit.
