Streamlit

Streamlit is an open-source app framework that lets data scientists and engineers build and share interactive web applications entirely in Python. It requires no front-end experience — just install it like any other Python library and run your script to see a live app. Streamlit is now part of Snowflake, offering both a free Community Cloud for public apps and enterprise-grade deployment via Snowflake.

• Pure Python API — Build full interactive apps using only Python; no HTML, CSS, or JavaScript needed.
• Instant interactivity — Add widgets like sliders, color pickers, date inputs, and file uploaders by simply declaring variables in your script.
• Auto-reloading — Apps automatically update as you save your source file, enabling rapid iteration.
• Community Cloud deployment — Deploy public apps for free by logging in with a GitHub account at share.streamlit.io.
• Snowflake integration — Deploy private, enterprise-grade apps on Snowflake with Git support, CI/CD, and enterprise security.
• Rich visualization support — Compatible with Bokeh, Altair, Plotly, Matplotlib, Vega-Lite, Deck.gl, and many more libraries.
• Streamlit Components — Extend the framework with custom or community-built components for additional UI elements.
• Live playground — Try Streamlit directly in the browser without any local installation via the online playground.
• Open-source — The core framework is available on GitHub under an Apache 2.0 license, with an active community forum and contributor ecosystem.
