🚀Streamlit

NEW

An open-source Python framework that turns scripts into shareable data apps and dashboards with minimal code.

DESCRIPTION

Streamlit enables rapid development of interactive data applications in pure Python, without needing web development expertise. It integrates seamlessly with popular Python libraries like pandas, NumPy, scikit-learn, Altair, and Plotly. Developers write a script and run it to produce a web app, supporting widgets, caching, session state, and simple deployment. Streamlit Cloud and various CI/CD setups streamline sharing and scaling apps. It is widely used for prototyping ML demos, internal analytics tools, and lightweight dashboards.
