## What it is
A collection of reference implementations of LangChain agents built as Streamlit apps, including streaming chat, memory, search-enabled chatbots, document chat, and SQL/pandas database chat examples. It serves as example code demonstrating LangChain and Streamlit integrations rather than a production library.

## Use cases
- build a chatbot with conversation memory in streamlit
- chat with my own documents using an llm
- ask questions about a sql database in natural language
- query a pandas dataframe with a chatbot
- learn how to build langchain agents
- add streaming llm responses to a web app
- collect user feedback on llm responses with langsmith traces

## When to choose
- you want copy-paste example code for LangChain + Streamlit apps
- you are prototyping chatbots, RAG, or agent demos quickly
- you want to see how StreamlitChatMessageHistory and callback integrations work

## When to avoid
- you need a production-ready, hardened application
- you want a maintained library with an API rather than example scripts
- you do not use Python, LangChain, or Streamlit

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: agent-framework, chatbot, rag, llm-inference
- domain: large-language-models, chatbots, developer-tools, tutorials
- platform: python, self-hosted
- tags: langchain, streamlit, example-apps, reference-implementations, chat-apps, ai-agents, web-server
