# Sandboxes overview

> Use managed sandboxes to safely execute code and interact with the filesystem in isolated environments.

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.

<Warning>
  Sandboxes are in private preview. APIs and features may change as we iterate. [Sign up for the waitlist](https://www.langchain.com/langsmith-sandboxes-waitlist?ref=docs.langchain.com) to get access.
</Warning>

From the [LangSmith homepage](https://smith.langchain.com), select **Sandboxes** to manage all your sandbox resources.
