Yes, there are a few limitations and potential challenges when using Streamlit for building complex data applications.

  • Limited customization: Streamlit has a built-in look and feel, which is generally nice, but it can be limiting if you need to heavily customize the appearance and behavior of your application.
  • Performance: Streamlit applications can be slow, especially if they are working with large datasets or complex computations. This is because Streamlit re-renders the entire application every time there is a change.
  • Scalability: Streamlit applications can be difficult to scale to handle a large number of users or concurrent requests.
  • Lack of support for some features: Streamlit does not support all of the features that are available in other web development frameworks, such as Django and Flask. This can be a limitation if you need to use a specific feature that is not supported by Streamlit.

Despite these limitations, Streamlit is a powerful and flexible tool for building a wide variety of data applications. It is particularly well-suited for rapid development and for users with no prior experience in web development.

Here are some tips for overcoming the limitations of Streamlit:

  • Use caching: Streamlit can cache expensive computations, so that they do not have to be recalculated every time the application is re-rendered. This can improve the performance of applications that work with large datasets.
  • Use a backend server: If you need to build a highly scalable application, you can use a backend server to handle the heavy lifting, such as processing large datasets and running complex computations. The Streamlit app can then simply display the results from the backend server.
  • Use a different web development framework: If you need to use a feature that is not supported by Streamlit, you can use a different web development framework, such as Django or Flask, to implement that feature. You can then integrate the Django or Flask app with your Streamlit app.

Overall, Streamlit is a powerful and flexible tool for building data applications. However, it is important to be aware of the limitations and potential challenges when using Streamlit for building complex applications. By following the tips above, you can overcome these limitations and build scalable and high-performance data applications with Streamlit.
