LangSmith Sandboxes is a new Private Preview feature that provides secure, ephemeral microVM-isolated environments for running untrusted agent-generated code. Key capabilities include single-line SDK setup, bring-your-own Docker image support, sandbox templates, pooling and autoscaling, long-running WebSocket sessions, persistent state across agent interactions, and an auth proxy that keeps secrets off the runtime. It integrates natively with LangSmith Deployment and the Deep Agents framework. Upcoming features include shared volumes across sandboxes, binary authorization, and full execution tracing inside the VM.
