Key point
LangChain manages the data plane infrastructure while keeping traces, evals, and agent deployments in the customer's own cloud account.
Details
- LangSmith Bring Your Own Cloud (BYOC) is now available on AWS (GA), Azure (Beta), and Google Cloud (Beta), allowing teams to keep sensitive data in their own cloud accounts while LangChain manages the data plane.
- BYOC splits LangSmith into a LangChain-managed control plane (auth, config, billing) and a customer-owned data plane (traces, prompts, datasets, agent deployments) within the customer's virtual network.
- AWS customers report benefits including continuous platform upgrades without maintenance windows, access to new features shortly after they ship on LangSmith Cloud, and automatic scaling for consistent uptime.
- Migration from self-hosted LangSmith is supported via an open-source tool that moves workspace resources (users, datasets, experiments, prompts) without downtime, with trace migration currently available on AWS.
- The LLM Gateway on the BYOC data plane supports 11 model providers out of the box, plus any OpenAI- or Anthropic-compatible endpoint, and Terraform modules for BYOC are public on GitHub.
