The Daytona SDK provides official Python and TypeScript interfaces for interacting with Daytona, enabling you to programmatically manage development environments and execute code. Python SDK supports both sync and async programming models where async classes are prefixed with Async.

Follow the step-by-step guide to create and run your first Daytona Sandbox for an AI Agent.

For steps on additional configuration, including setting environment variables as well as accessing experimental features on our staging deployment, visit Configuration.

Install the Daytona SDK

Daytona provides official Python and TypeScript SDKs for interacting with the Daytona platform. Install the SDK using your preferred method:

Python
TypeScript

pip install daytona

# Using npm
npm install @daytonaio/sdk

# Using yarn

yarn add @daytonaio/sdk

# Using pnpm

pnpm add @daytonaio/sdk

Run Code Inside a Sandbox

Run the following code to create a Daytona Sandbox and execute commands:

Python
TypeScript

from daytona import Daytona, DaytonaConfig

# Initialize the Daytona client
daytona = Daytona(DaytonaConfig(api_key="YOUR_API_KEY"))

# Create the Sandbox instance
sandbox = daytona.create()

# Run code securely inside the Sandbox
response = sandbox.process.code_run('print("Sum of 3 and 4 is " + str(3 + 4))')
if response.exit_code != 0:
    print(f"Error running code: {response.exit_code} {response.result}")
else:
    print(response.result)

# Clean up the Sandbox
sandbox.delete()

import { Daytona } from '@daytonaio/sdk'

async function main() {
  // Initialize the Daytona client
  const daytona = new Daytona({
    apiKey: 'YOUR_API_KEY',
  })

  let sandbox;
  try {
    // Create the Sandbox instance
    sandbox = await daytona.create({
      language: "python",
    });
    // Run code securely inside the Sandbox
    const response = await sandbox.process.codeRun(
      'print("Sum of 3 and 4 is " + str(3 + 4))'
    );
    if (response.exitCode !== 0) {
      console.error("Error running code:", response.exitCode, response.result);
    } else {
      console.log(response.result);
    }
  } catch (error) {
    console.error("Sandbox flow error:", error);
  } finally {
    // Clean up the Sandbox
    if (sandbox) {
      await sandbox.delete();
    }
  }
}

main().catch(console.error)

Python
TypeScript

python main.py

npx tsx ./index.ts

Preview Your App

The following snippet uploads a file containing a simple Flask app to a Daytona Sandbox. The web server runs on port 3000 and is accessible through the provided preview URL:

Python
TypeScript

from daytona import Daytona, DaytonaConfig, SessionExecuteRequest

daytona = Daytona(DaytonaConfig(api_key="YOUR_API_KEY"))

sandbox = daytona.create()

Connect to an LLM

The following snippet connects to an LLM using the Anthropic API and asks Claude to generate code for getting the factorial of 25 and then executes it inside of a Daytona Sandbox:

Python
TypeScript

import os
import re
import requests
from daytona import Daytona, DaytonaConfig
from dotenv import load_dotenv

load_dotenv()

daytona = Daytona(DaytonaConfig())

sandbox = daytona.create()

def get_claude_response(api_key, prompt):
    url = "https://api.anthropic.com/v1/messages"
    headers = {
        "x-api-key": api_key,
        "anthropic-version": "2023-06-01",
        "Content-Type": "application/json"
    }
    data = {
        "model": "claude-3-7-sonnet-latest",
        "max_tokens": 256,
        "messages": [{"role": "user", "content": prompt}]
    }
    response = requests.post(url, json=data, headers=headers)
    if response.status_code == 200:
        content = response.json().get("content", [])
        return "".join([item["text"] for item in content if item["type"] == "text"])
    else:
        return f"Error {response.status_code}: {response.text}"

prompt = "Python code that returns the factorial of 25. Output only the code. No explanation. No intro. No comments. Just raw code in a single code block."

result = get_claude_response(os.environ["ANTHROPIC_API_KEY"], prompt)

code_match = re.search(r"```python\n(.*?)```", result, re.DOTALL)

code = code_match.group(1) if code_match else result
code = code.replace('\\', '\\\\')

# Run Python code inside the Sandbox and get the output

response = sandbox.process.code_run(code)
print("The factorial of 25 is", response.result)

Running the snippet:

ANTHROPIC_API_KEY="your-anthropic-api-key"
DAYTONA_API_KEY="your-daytona-api-key"
DAYTONA_TARGET=us
python claude-example.py

> The factorial of 25 is 15511210043330985984000000

import { Daytona } from '@daytonaio/sdk'
import * as dotenv from 'dotenv'
import axios from 'axios'

dotenv.config()

const daytona = new Daytona()

async function getClaudeResponse(apiKey: string, prompt: string): Promise<string> {
  const url = "https://api.anthropic.com/v1/messages"
  const headers = {
    "x-api-key": apiKey,
    "anthropic-version": "2023-06-01",

    "messages": [{"role": "user", "content": prompt}]
  }

  try {
    const response = await axios.post(url, data, { headers })
    if (response.status === 200) {
      const content = response.data.content || []
      return content
        .filter((item: any) => item.type === "text")
        .map((item: any) => item.text)
        .join("")
    } else {
      return `Error ${response.status}: ${response.statusText}`
    }
  } catch (error: any) {
    return `Error: ${error.message}`
  }
}

async function main() {
  const sandbox = await daytona.create()

  const prompt = "Python code that returns the factorial of 25. Output only the code. No explanation. No intro. No comments. Just raw code in a single code block."

  const result = await getClaudeResponse(process.env.ANTHROPIC_API_KEY || "", prompt)

  // Extract code from the response using regex
  const codeMatch = result.match(/```python\n(.*?)```/s)

  let code = codeMatch ? codeMatch[1] : result
  code = code.replace(/\\/g, '\\\\')

  // Run the extracted code in the sandbox
  const response = await sandbox.process.codeRun(code)
  console.log("The factorial of 25 is", response.result)
}

main().catch(console.error)

Running the snippet:

ANTHROPIC_API_KEY="your-anthropic-api-key"
DAYTONA_API_KEY="your-daytona-api-key"
DAYTONA_TARGET=us
npx ts-node claude-example.ts

> The factorial of 25 is 15511210043330985984000000

Additional Examples

Use the Daytona SDK Python examples or TypeScript/JavaScript examples to create a Sandbox and run your code.

Speed up your development on Daytona using LLMs. Copy the /llms.txt files and include them into your projects or chat context: llms-full.txt or llms.txt

Learn more by checking out the Daytona SDK repository on GitHub.

Multiple Runtime Support

The Daytona TypeScript SDK works across multiple JavaScript runtimes including Node.js, Deno, Bun, browsers, and serverless platforms (Cloudflare Workers, AWS Lambda, Azure Functions, etc.).

Daytona in Vite Projects

When using Daytona SDK in a Vite-based project, you need to configure node polyfills to ensure compatibility. Add the following configuration to your vite.config.ts file in the plugins array:

import { nodePolyfills } from 'vite-plugin-node-polyfills'

export default defineConfig({
  plugins: [
    // ... other plugins
    nodePolyfills({
      globals: { global: true, process: true, Buffer: true },
      overrides: {
        path: 'path-browserify-win32',
      },
    }),
  ],
  // ... rest of your config
})

Daytona in Next.js Projects

When using Daytona SDK in a Next.js project, you need to configure node polyfills to ensure compatibility with Webpack and Turbopack bundlers (depending on what you’re using). Add the following configuration to your next.config.ts file:

import type { NextConfig } from 'next'
import NodePolyfillPlugin from 'node-polyfill-webpack-plugin'
import { env, nodeless } from 'unenv'

const { alias: turbopackAlias } = env(nodeless, {})

const nextConfig: NextConfig = {
  // Turbopack
  experimental: {
    turbo: {
      resolveAlias: {
        ...turbopackAlias,
      },
    },
  },
  // Webpack
  webpack: (config, { isServer }) => {
    if (!isServer) {
      config.plugins.push(new NodePolyfillPlugin())
    }
    return config
  },
}

export default nextConfig

Setting up the Daytona CLI

If you want to use images from your local device or simply prefer managing your Sandboxes using the command line interface, install the Daytona CLI by running:

Mac/Linux
Windows

brew install daytonaio/cli/daytona

powershell -Command "irm https://get.daytona.io/windows | iex"
