Quick Start

Connect to Browserless using either Puppeteer or Playwright through Chrome's DevTools Protocol (CDP) using websockets. This is the primary and recommended way to connect to Browserless, as it provides a stable and reliable connection.

Follow these steps to get started with Browserless:

1. Get Your API Token

   • Go to the Browserless dashboard
   • Sign up or log in to your account
   • Copy your API token from the dashboard

   

2. Install Library

   Choose your preferred automation library and install it:

   Puppeteer

   JavaScript

   npm install puppeteer-core

   Python

   pip install pyppeteer

   Playwright

   JavaScript

   npm install playwright-core

   Python

   pip install playwright

   Java

   <dependency>
     <groupId>com.microsoft.playwright</groupId>
     <artifactId>playwright</artifactId>
     <version>1.40.0</version>
   </dependency>

   C#

   dotnet add package Microsoft.Playwright

3. Run Your First Example

   Here's a complete working example:

   Puppeteer

   JavaScript

   import puppeteer from "puppeteer-core";
   
   const TOKEN = "YOUR_API_TOKEN_HERE"; // Replace with your actual token
   
   async function getPageTitle() {
     // Connect to Browserless using WebSocket endpoint
     const browser = await puppeteer.connect({
       browserWSEndpoint: `wss://production-sfo.browserless.io?token=${TOKEN}`,
     });
   
     const page = await browser.newPage();
   
     // Navigate to the target website
     await page.goto("https://www.example.com/");
   
     // Get the page title
     const title = await page.title();
     console.log(`The page's title is: ${title}`);
   
     // Clean up resources
     await browser.close();
   }
   
   getPageTitle().catch(console.error);

   Output

   The page's title is: Example Domain

   Python

   import asyncio
   from pyppeteer import connect
   
   TOKEN = "YOUR_API_TOKEN_HERE"
   
   async def get_page_title():
       # Connect to Browserless using WebSocket endpoint
       browser = await connect({
           "browserWSEndpoint": f"wss://production-sfo.browserless.io/?token={TOKEN}"
       })
   
       page = await browser.newPage()
       await page.goto("https://www.example.com/")
   
       title = await page.title()
       print(f"The page's title is: {title}")
   
       await browser.close()
   
   if __name__ == "__main__":
       asyncio.run(get_page_title())

   Output

   The page's title is: Example Domain

   Playwright

   JavaScript

   import { chromium } from "playwright-core";
   
   const TOKEN = "YOUR_API_TOKEN_HERE"; // Replace with your actual token
   
   async function getPageTitle() {
     // Connect to Browserless using CDP (recommended method)
     const browser = await chromium.connectOverCDP(
       `wss://production-sfo.browserless.io?token=${TOKEN}`
     );
   
     const context = await browser.newContext();
     const page = await context.newPage();
   
     // Navigate to the target website
     await page.goto("https://www.example.com/");
   
     // Get the page title
     const title = await page.title();
     console.log(`The page's title is: ${title}`);
   
     // Clean up resources
     await browser.close();
   }
   
   getPageTitle().catch(console.error);

   Output

   The page's title is: Example Domain

   Python

   from playwright.sync_api import sync_playwright
   
   TOKEN = "YOUR_API_TOKEN_HERE"  # Replace with your actual token
   
   def get_page_title():
       with sync_playwright() as p:
           # Connect to Browserless using CDP (recommended method)
           browser = p.chromium.connect_over_cdp(
               f"wss://production-sfo.browserless.io?token={TOKEN}"
           )
   
           context = browser.new_context()
           page = context.new_page()
   
           # Navigate to the target website
           page.goto("https://www.example.com/")
   
           # Get the page title
           title = page.title()
           print(f"The page's title is: {title}")
   
           # Clean up resources
           browser.close()
   
   if __name__ == "__main__":
       get_page_title()

   Output

   The page's title is: Example Domain
