## What it is
LangChainHub is a community repository of reusable LangChain artifacts such as prompts, chains, and agents, inspired by Hugging Face Hub. It is being replaced by the hosted LangChain Hub product at smith.langchain.com/hub.

## Use cases
- find high-quality prompts for langchain
- share reusable llm prompts with the community
- load a prebuilt agent into langchain
- discover chains for common llm tasks
- browse prompt templates by use case

## When to choose
- you use LangChain and want ready-made prompts, chains, or agents
- you want to contribute prompt artifacts to a shared collection

## When to avoid
- you want the actively maintained hosted hub - use smith.langchain.com/hub instead
- you don't use the LangChain ecosystem

## Facets
- artifact type: dataset
- maturity: maintenance
- function: prompt-engineering, agent-framework, rag
- domain: large-language-models, artificial-intelligence
- platform: python
- tags: langchain, prompt-collection, llm-artifacts, hub, community-contributed, ai-agents
