LangSmith BYOC moves the data plane into your VPC on AWS, Azure, and Google Cloud

On November 3, 2026, LangChain announced LangSmith BYOC is generally available on AWS and in beta on Azure and Google Cloud: traces, evals, and agent deployments stay in your own cloud account while LangChain operates the infrastructure. Teams under compliance constraints can drop self-hosting without repatriating maintenance or migrating their data.
