We're happy to announce that E2B is a sandbox provider in the new [OpenAI Agents SDK](https://developers.openai.com/api/docs/guides/agents). 

With this release, agents built with the OpenAI Agents SDK will get their own sandboxes featuring a custom environment with resource isolation, security boundaries, and persistence, requiring no infrastructure setup. Your agents will be able to:

- Edit files and run shell commands in isolated environments
- Maintain temporary workspace state across steps
- Generate frontend output with live preview URLs
- Produce artifacts you can review before publishing
- Run multiple sandboxes in parallel for concurrent workloads

## **Integration takes just a few lines of code**

You can set up computer use with just a few lines of code. You just need to define your tools, the agent to use them, and something to get started.

## **See it in action**

In the demo below, we walk through the full workflow of creating a landing page:

1. **Set up a sandbox session** with the E2B SDK and define a builder agent with file-editing capabilities.
2. **Generate a landing page from scratch**: the agent writes HTML/CSS, deploys into the sandbox, and serves it at a preview URL.
3. **Iterate with diffs**: instead of rewriting everything, the agent applies patches for faster turnaround.
4. **Compare variants side by side**: each variant lives at its own URL, making visual comparison straightforward.
5. **Parallelize**: spin up multiple sandboxes simultaneously, each running an independent agent, to generate several variants at once.

The result: multiple landing page variants, each pre-viewable at its own URL, generated in parallel with minimal code.
