Coding agents like Claude Code, Codex, and Amp 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

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 for any agent
  4. Scalability — run many sandboxes in parallel, each with its own agent on a separate task

​
How It Works

  1. Create a sandbox — use a pre-built template or build your own 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

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