🚀 Getting started

The E2B Desktop Sandbox is built on top of E2B Sandbox.

1. Get E2B API key

Sign up at E2B and get your API key. Set environment variable E2B_API_KEY with your API key.

2. Install SDK

Python

pip install e2b-desktop

JavaScript

npm install @e2b/desktop

3. Create Desktop Sandbox

Python

from e2b_desktop import Sandbox

# Create a new desktop sandbox
desktop = Sandbox()

# Launch an application
desktop.launch('google-chrome')  # or vscode, firefox, etc.

# Wait 10s for the application to open
desktop.wait(10000)

# Stream the application's window
# Note: There can be only one stream at a time
# You need to stop the current stream before streaming another application
desktop.stream.start(
    window_id=desktop.get_current_window_id(), # if not provided the whole desktop will be streamed
    require_auth=True
)

# Get the stream auth key
auth_key = desktop.stream.get_auth_key()

# Print the stream URL
print('Stream URL:', desktop.stream.get_url(auth_key=auth_key))

# Kill the sandbox after the tasks are finished
# desktop.kill()

JavaScript

import { Sandbox } from '@e2b/desktop'

// Start a new desktop sandbox
const desktop = await Sandbox.create()

// Launch an application
await desktop.launch('google-chrome') // or vscode, firefox, etc.

// Wait 10s for the application to open
await desktop.wait(10000)

// Stream the application's window
// Note: There can be only one stream at a time
// You need to stop the current stream before streaming another application
await desktop.stream.start({
  windowId: await desktop.getCurrentWindowId(), // if not provided the whole desktop will be streamed
  requireAuth: true,
})

// Get the stream auth key
const authKey = desktop.stream.getAuthKey()

// Print the stream URL
console.log('Stream URL:', desktop.stream.getUrl({ authKey }))

// Kill the sandbox after the tasks are finished
// await desktop.kill()

Features

Streaming desktop's screen

Python

from e2b_desktop import Sandbox
desktop = Sandbox()

# Start the stream
desktop.stream.start()

# Get stream URL
url = desktop.stream.get_url()
print(url)

# Get stream URL and disable user interaction
url = desktop.stream.get_url(view_only=True)
print(url)

# Stop the stream
desktop.stream.stop()

JavaScript

import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()

// Start the stream
await desktop.stream.start()

// Get stream URL
const url = desktop.stream.getUrl()
console.log(url)

// Get stream URL and disable user interaction
const url = desktop.stream.getUrl({ viewOnly: true })
console.log(url)

// Stop the stream
await desktop.stream.stop()

Streaming with password protection

Python

from e2b_desktop import Sandbox
desktop = Sandbox()

# Start the stream
desktop.stream.start(
    require_auth=True  # Require authentication with an auto-generated key
)

# Retrieve the authentication key
auth_key = desktop.stream.get_auth_key()

# Get stream URL
url = desktop.stream.get_url(auth_key=auth_key)
print(url)

# Stop the stream
desktop.stream.stop()

JavaScript

import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()

// Start the stream
await desktop.stream.start({
  requireAuth: true, // Require authentication with an auto-generated key
})

// Retrieve the authentication key
const authKey = await desktop.stream.getAuthKey()

// Get stream URL
const url = desktop.stream.getUrl({ authKey })
console.log(url)

// Stop the stream
await desktop.stream.stop()

Streaming specific application

Warning

• Will raise an error if the desired application is not open yet
• The stream will close once the application closes
• Creating multiple streams at the same time is not supported, you may have to stop the current stream and start a new one for each application

Python

from e2b_desktop import Sandbox
desktop = Sandbox()

# Get current (active) window ID
window_id = desktop.get_current_window_id()

# Get all windows of the application
window_ids = desktop.get_application_windows("Firefox")

# Start the stream
desktop.stream.start(window_id=window_ids[0])

# Stop the stream
desktop.stream.stop()

JavaScript

import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()

// Get current (active) window ID
const windowId = await desktop.getCurrentWindowId()

// Get all windows of the application
const windowIds = await desktop.getApplicationWindows('Firefox')

// Start the stream
await desktop.stream.start({ windowId: windowIds[0] })

// Stop the stream
await desktop.stream.stop()

desktop.files.write("/home/user/index.js", "console.log('hello')") # First create the file
desktop.open("/home/user/index.js") # Then open it

JavaScript

import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()

Under the hood

The desktop-like environment is based on Linux and Xfce at the moment. We chose Xfce because it's a fast and lightweight environment that's also popular and actively supported. However, this Sandbox template is fully customizable and you can create your own desktop environment. Check out the sandbox template's code here.
