This repository is a curated collection of over 30 independent Streamlit in Snowflake (SiS) demo applications, each self-contained in its own folder. The demos span a wide range of use cases including business intelligence dashboards, LLM-powered chatbots (Cortex, DeepSeek-R1, RAG), geospatial H3 visualizations, custom UI components (AgGrid, ECharts, Slickgrid), CI/CD pipelines with Snowflake CLI, and embedding SiS into external portals via Next.js. Each app includes a `streamlit_app.py` entry point, a `data/creation_script.sql` for Snowflake object setup, and sample data. The code is educational, heavily commented, and demonstrates patterns like caching, dynamic page navigation, and local/cloud-aware connections. While the apps are not production-grade (some hardcoded values, duplication), they serve as excellent reference implementations for building SiS applications.
