Streamlit custom components are community-built UI widgets that extend the core API with specialized features. They provide capabilities not available natively, such as live keyup inputs, interactive data grids, and Folium maps for geospatial dashboards.

Install the desired custom component package from PyPI, verify its compatibility with your Streamlit version, then import and use it in your Python script following the component's documentation. This allows you to add advanced widgets and exploratory visual tools.

Yes, but you must verify compatibility with your specific Streamlit version before adoption. Checking compatibility and maintenance considerations reduces the risk of breakage when Streamlit updates its core API.

You should use third-party custom components when Streamlit's core API lacks the interactive widgets you need. They provide specialized UI elements like live keyup inputs, interactive grids, and Folium maps without requiring custom builds or workarounds.

Before adopting a third-party Streamlit component, check its compatibility with your Streamlit version and review its maintenance status. These checks reduce breakage risks and ensure the custom UI widget integrates predictably into your data app.
