# Overview

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

As business needs change, you can scale computing resources up or down in real time. UCloud Sandbox supports billing based on the actual resources used, which can save you computing costs.

## Recommended learning path

Start by following the order of "Run first → In-depth capabilities → Build a custom environment":

### Step one: Get started quickly

1. [Prerequisites and Certification](/docs/agent-sandbox/product/prerequisites.md) - Obtain API Key and configure the environment
2. [SDK Quick Start](/docs/agent-sandbox/product/quickstart.md) - Create your first sandbox in 5 minutes
3. [CLI Guide](/docs/agent-sandbox/product/cli.md) - Getting Started with Command Line Tools
4. [Switch Region](/docs/agent-sandbox/product/region.md) - Learn how to switch regions
5. [Billing Instructions](/docs/agent-sandbox/product/fee.md) - Understand the sandbox billing situation

### Step 2: Use the sandbox in depth

1. [Sandbox life cycle](/docs/agent-sandbox/sandbox/lifecycle.md) - timeout, suspension, recovery and destruction
2. [Command execution](/docs/agent-sandbox/commands/overview.md) - Run commands in the sandbox
3. [File System](/docs/agent-sandbox/filesystem/overview.md) - File reading, writing and transmission
4. [Network Access](/docs/agent-sandbox/network/internet-access.md) - Control sandbox Internet access

### Step 3: Build a custom template

1. [Template Quick Start](/docs/agent-sandbox/template/quickstart.md) - Build custom templates
2. [How the template works](/docs/agent-sandbox/template/how-it-works.md) - Detailed explanation of the snapshot mechanism
3. [Template Examples](/docs/agent-sandbox/template/examples/claude-code.md) - Template examples for common scenarios

## Typical application scenarios

- **AI Agent Code Execution**: Safely run code generated by LLM and isolate risks
- **Automated Testing**: Run test cases in an isolated environment
- **Data Analysis**: Provides a sandbox environment with pre-installed analysis tools
- **Education and Training**: Provide students with an independent experimental environment
