🚀 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

npm install @e2b/desktop

3. Create Desktop Sandbox

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

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)

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

Streaming with password protection

import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()

// Start the stream
await desktop.stream.start({
  requireAuth: true, // Enable 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 throw 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

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()

Mouse control

import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()

await desktop.doubleClick()
await desktop.leftClick()
await desktop.leftClick(100, 200)
await desktop.rightClick()
await desktop.rightClick(100, 200)
await desktop.middleClick()
await desktop.middleClick(100, 200)
await desktop.scroll(10) // Scroll by the amount. Positive for up, negative for down.
await desktop.moveMouse(100, 200) // Move to x, y coordinates
await desktop.drag([100, 100], [200, 200]) // Drag using the mouse
await desktop.mousePress('left') // Press the mouse button
await desktop.mouseRelease('left') // Release the mouse button

Keyboard control

import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()

// Write text at the current cursor position with customizable typing speed
await desktop.write('Hello, world!')
await desktop.write('Fast typing!', { chunkSize: 50, delayInMs: 25 }) // Faster typing

// Press keys
await desktop.press('enter')
await desktop.press('space')
await desktop.press('backspace')
await desktop.press(['ctrl', 'c']) // Key combination

Window control

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')

// Get window title
const title = await desktop.getWindowTitle(windowId)

Screenshot

import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()
const image = await desktop.screenshot()
// Save the image to a file
fs.writeFileSync('screenshot.png', image)

Open file

import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()

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

Launch applications

import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()

// Launch the application
await desktop.launch('google-chrome')

Run any bash commands

import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()

// Run any bash command
const out = await desktop.commands.run('ls -la /home/user')
console.log(out)

Wait

import { Sandbox } from '@e2b/desktop'

const desktop = await Sandbox.create()
await desktop.wait(1000) // Wait for 1 second

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.
