Trust AssessmentAI Assessment

LangChain is a TypeScript framework published by LangChain under MIT license for building LLM-powered applications through composable components and third-party integrations. The package shows strong adoption with 54.2M weekly downloads and active maintenance from 8 maintainers, though 22 historical CVEs indicate the framework has required ongoing security attention. The minimal dependency footprint of 5 packages reduces supply chain exposure, making this a widely-trusted choice for AI application development.
