# Overview

UCloud Sandbox provides you with secure and reliable elastic sandbox computing services. In just a few seconds, you can obtain and enable sandboxes with full operating system capabilities in the cloud for executing AI Agent-generated code, running automated tests, or executing untrusted scripts.

As business needs change, you can scale compute resources up or down in real-time. UCloud Sandbox supports billing based on actual resource usage, which can help you save computing costs.
