🚀 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

pip install e2b-desktop

3. Create Desktop Sandbox

from e2b_desktop import Sandbox

# Create a new desktop sandbox
desktop = Sandbox.create()

# 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()

Features

Streaming desktop's screen

from e2b_desktop import Sandbox
desktop = Sandbox.create()

# Start the stream
desktop.stream.start()

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

# Stop the stream
desktop.stream.stop()

Streaming with password protection

from e2b_desktop import Sandbox
desktop = Sandbox.create()

# Start the stream
desktop.stream.start(
    require_auth=True  # Enable 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()

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

from e2b_desktop import Sandbox
desktop = Sandbox.create()

# 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()

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.
