# LangChain's Second Birthday

**[LangChain](https://daily.dev/sources/langchain)** · 8 min read · 0 upvotes · 0 comments

## Summary

Marking two years since the langchain Python package launched, LangChain's founder reflects on the company's evolution from a single open source library into three products: langchain, LangGraph (agent orchestration), and LangSmith (observability and evaluation). The ecosystem grew from 3 LLM providers to over 70, with 700+ integrations. Community metrics doubled or more: contributors from 2,000 to 4,000, apps from 30k to 132k, and downloads from 20 million to 130 million+. The piece closes with a look ahead and ways to join the community.
