LangChain
LangChain is an MIT‑licensed open‑source library that lets you build, test, and deploy AI agents using pre‑built architectures and over 1,000 model/tool integrations. It runs on Python and can be combined with the LangSmith platform for observability, evaluation, and deployment, but the core framework itself is free to use.
