Sandboxes are isolated environments that allow agents to safely execute potentially risky operations—like running arbitrary code or interacting with the filesystem—without affecting your main infrastructure.
Sandboxes are in private preview. APIs and features may change as we iterate. Sign up for the waitlist to get access.
From the LangSmith homepage, select Sandboxes to manage all your sandbox resources. Sandboxes overview page
