# Overview

**Novita Agent Sandbox** provides isolated, stateful execution environments for AI agents.
You can use a Sandbox to run code, install dependencies, access files, use browsers, and preserve execution state across sessions without managing infrastructure.

## Core Concepts

Agent Sandbox is built around three core concepts: Sandbox, Template, and Snapshot.

### Sandbox

A Sandbox is an isolated execution environment where your agent performs tasks.
Inside a Sandbox, your agent can run commands, read and write files, install dependencies, and use browser-based workflows. Each Sandbox has its own filesystem and runtime environment.

### Template

A Template defines the environment a Sandbox starts with.
Templates help you create consistent Sandboxes with predefined dependencies, configuration, and setup steps. Use Templates when you want multiple Sandboxes to start from the same prepared environment.

### Snapshot

A Snapshot saves the current state of a Sandbox as a reusable environment.
Snapshots are useful after you have configured a Sandbox, installed dependencies, or generated files that you want to reuse. New Sandboxes can be created from a Snapshot without repeating the same setup steps.

## When to Use Agent Sandbox

Agent Sandbox is designed for workloads where agents need an isolated environment to execute tasks, keep state, or reuse prepared environments.
Common use cases include:

* Coding agents that run code, install packages, and execute tests
* Browser agents that automate web workflows
* Data analysis agents that process files and generate reports
* Research or RL workloads that need many isolated environments

## Pricing

Agent Sandbox provides per-second billing for CPU and RAM. Storage — encompassing templates, paused sandboxes, and snapshots — is now subject to daily charges. See the [pricing](/guides/sandbox-pricing) page for more details.

## Getting Started

You can start and manage your Agent Sandboxes through SDK or CLI. For details, please refer to the [quick start](/guides/sandbox-your-first-agent-sandbox) page.
