What it is

Streamlit is a framework that enables developers and data scientists to create interactive web applications for visualizing and sharing data insights quickly. It simplifies the process of building user interfaces with Python code alone.

Streamlit stands out for its simplicity and speed in creating data apps, making it an ideal choice for rapid prototyping and sharing insights without deep frontend expertise.

When it fits — and when it doesn’t

A good fit for

  • Developers who need a quick way to prototype and share data apps without extensive frontend knowledge.

  • Data scientists looking to create interactive dashboards with minimal setup.

Look elsewhere if

  • Projects requiring complex, highly customized user interfaces beyond basic widgets

  • Teams needing enterprise-grade security features out of the box

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Limited language support, restricted to Python

    Core framework is built around Python and does not natively support other languages like JavaScript or R

  2. 02

    Performance issues with large datasets

    Real-time updates can cause lag when handling extensive data sets, impacting user experience

What it does well

  • Rapid prototyping and deployment of data apps

  • Live updating UI with Python code changes

  • Built-in support for interactive widgets
