Ship a data app from a Python script — no frontend required.
Streamlit turns a Python script into an interactive web app with a few st.call lines. Data scientists love it for ML demos, dashboards, and internal tools. Streamlit Community Cloud hosts them free.
Who it's for: Data scientists and ML engineers who can write Python but not React, and need to share results fast.
No HTML/JS — just st.write and widgets.
Sliders, buttons, and file uploaders in one line.
Community Cloud deploys from GitHub.
Native plotting with Matplotlib, Plotly, Altair.
For turning a model into a demo others can click, nothing is faster than Streamlit. Free and open.
