About langchain
LangChain is an open source framework for building agents and LLM powered applications, written in Python and released under the MIT license. It lives in the AI and machine learning ecosystem, specifically among AI development platforms, and it works by chaining together interoperable components and third party integrations so that AI application development becomes simpler. The project describes itself as the agent engineering platform, and its abstractions are designed to keep applications working as the underlying technology evolves.

About langroid
Langroid is a Python framework for building applications powered by large language models through multiple agents. It comes from researchers at CMU and UW Madison, and it lives in the Python AI development ecosystem. Developers create agents, give them optional components such as a language model, a vector store, and tools or functions, and assign tasks that the agents solve by exchanging messages.
