Coding agents like [Claude Code](https://docs.anthropic.com/en/docs/agents-and-tools/claude-code/overview), [Codex](https://github.com/openai/codex), and [Amp](https://ampcode.com/) can write, debug, and refactor code autonomously. E2B sandboxes give each agent a full Linux environment with terminal, filesystem, and git — completely isolated from your infrastructure. Pre-built templates mean you can go from zero to a running agent in a single API call.

## Why Use a Sandbox [#why-use-a-sandbox]

Running coding agents directly on your machine or servers means giving AI-generated code unrestricted access to your environment. E2B sandboxes solve this:

1. **Isolation** — agent-generated code runs in a secure sandbox, never touching your production systems or local machine
2. **Full dev environment** — terminal, filesystem, git, and package managers are all available out of the box, so agents work like a developer would
3. **Pre-built templates** — ready-made templates for popular agents get you started fast, and you can [build your own](/docs/template/quickstart) for any agent
4. **Scalability** — run many sandboxes in parallel, each with its own agent on a separate task

## How It Works [#how-it-works]

1. **Create a sandbox** — use a pre-built template or [build your own](/docs/template/quickstart) with any agent installed
2. **Agent gets a full environment** — terminal, filesystem, git access, and any tools installed in the template
3. **Agent works autonomously** — it reads the codebase, writes code, runs tests, and iterates until the task is done
4. **Extract results** — pull out the git diff, structured output, or modified files via the SDK. The sandbox stays available for follow-up work, or you can pause it to pick up later

## Agent Examples [#agent-examples]

Since each sandbox is a full Linux environment, you can run any coding agent — just install it in a [custom template](/docs/template/quickstart). E2B also provides pre-built templates for popular agents to get you started quickly.
