🔥 Gradio vs Streamlit: Guide to Choosing the Right Framework for LLM and Generative AI Applications

by | Oct 30, 2023 | AI, Software Development

Frameworks are a big help to developers, making it easier to build apps by offering ready-made solutions for common tasks. They cut down on repetitive coding, allowing developers to focus more on the unique parts of their project. This is especially handy in Generative AI Applications, where creating user-friendly interfaces is key. With frameworks like Gradio and Streamlit, developers can build advanced apps with just a few lines of code, ensuring robust communication, security, and the ability to scale the app easily. They simplify the journey from idea to a working app, saving time and ensuring a smooth user experience.

Gradio Studio creates Widgets for GenAI and LLM Applications with few lines of code
With few lines of code, frameworks like Gradio and Streamlit offer developers the ability to streamline development and ensure best practices building GenAI and AI apps and deploying AI models.

Gradio and Streamlit are two frameworks that have made a name for themselves in this sphere. This piece dives into a comparative analysis of these frameworks, with a particular focus on building a simple LLM chat application.

Unpacking Gradio and Streamlit

Gradio and Streamlit are structured to aid developers in building and deploying machine learning web applications. Both frameworks bring different strengths to the table, enabling a wide range of applications from simple interactive interfaces to complex web applications with advanced customizations. To have a deepdive on this topic, take a look in the article by Thimotee Legrand or this Medium Article by Shahab Hasan.

Getting started with the LLM Chat application

To have a better comparison, we will create a basic LLM chat application using both frameworks to understand their workings better.

Gradio minimal Code Example for a LLM chat:

import gradio as gr

def llm_chat(user_input):
    # Assume get_response is a function to get model response
    response = get_response(user_input)
    return response

iface = gr.Interface(fn=llm_chat, inputs="text", outputs="text")

In this Gradio example, a function llm_chat is defined to process the user input and get the model’s response. A Gradio interface is then created to handle text input and output.

Streamlit Code Snippet:

import streamlit as st

st.title('LLM Chat')

user_input = st.text_input("You: ", "")
if user_input:
    # Assume get_response is a function to get model response
    response = get_response(user_input)
    st.write(f'Model: {response}')

In the Streamlit example, a text input box is created for the user input, and the model’s response is displayed once the user enters a message.

Simplicity and User Interaction

Gradio is hailed for its simplicity and ability to create interactive UIs with minimal code. The framework’s intuitive nature allows developers to focus on the logic rather than the boilerplate code. Great overview for building UI dahsboards with Gradio in EdgeML blog.

Streamlit also offers a user-friendly platform but with more focus on creating interactive dashboards and visualizations, making it suitable for a broader range of applications.

Customization and Community Support

Streamlit excels in customization, backed by a vibrant community and extensive documentation. This robust support network can be invaluable when venturing into complex projects.

Gradio, while not as flexible in customization, holds its own with a user-centric approach, focusing on delivering interactive UIs.

Security Considerations

Gradio steps up with security features like password protection and encryption, ensuring a secure environment for application deployment.

Security features in Streamlit weren’t as prominently mentioned, suggesting a potential area for further investigation for developers concerned with security.

Gradio and Streamlit are both popular frameworks for developing LLM and generative AI applications

This comprehensive dive aims to equip developers with the knowledge to navigate the choice between Gradio and Streamlit, aligning with their project demands and personal preferences.


Gradio and Streamlit are powerful frameworks designed to facilitate the development of web applications, especially in the context of machine learning and data science. While both are Python-based and user-friendly, they cater to slightly different audiences and project requirements.

Gradio shines with its ease of use and is particularly friendly for data scientists and individuals with limited web development experience. It simplifies the process of creating interactive user interfaces for machine learning models and offers basic customization along with security features like password protection and encryption.

On the other hand, Streamlit is known for its flexibility and extensive customization options, making it a preferred choice for both software developers and data scientists. It’s well-suited for creating interactive dashboards and visualizations. Streamlit also boasts a larger community and more extensive documentation, which can be invaluable for troubleshooting and exploring advanced functionalities.

The choice between Gradio and Streamlit would largely depend on the specific needs of the project. For simpler, interactive UI-focused applications, Gradio might be the better choice. Conversely, for projects requiring advanced customization, interactive dashboards, and a strong community support, Streamlit could be more fitting.

In a nutshell, both frameworks are robust and capable, each with its unique set of features and advantages. The comparison provided aims to equip developers with a clearer understanding to make an informed decision based on their project demands and personal or team expertise. As we see more and more exciting integrations of GenAI and LLMs across industries (as in a recent example of SPOT with LLM integration), the importance of these frameworks is expected to grow.
