AsyncSandbox

Python
class AsyncSandbox(SandboxSetup, SandboxApi)
E2B cloud sandbox is a secure and isolated cloud environment. The sandbox allows you to:
  • Access Linux OS
  • Create, list, and delete files and directories
  • Run commands
  • Run isolated code
  • Access the internet
Check docs here. Use the AsyncSandbox.create() to create a new sandbox. Example:
Python
from e2b import AsyncSandbox

sandbox = await AsyncSandbox.create()

​
