What is the PuppeteerSharp Library for C#?

If you are a developer working with C#, you might have come across the PuppeteerSharp library. In this blog post, we will explore what PuppeteerSharp is and how it can be used in C# development.

What is PuppeteerSharp?

PuppeteerSharp is a .NET port of the popular Puppeteer library, which provides a high-level API for controlling headless Chrome or Chromium browsers. It allows developers to automate browser tasks, such as generating screenshots, crawling websites, or testing web pages.

Features of PuppeteerSharp

PuppeteerSharp offers a wide range of features that make it a powerful tool for browser automation in C#:

  • Headless browser automation: PuppeteerSharp allows you to control a headless Chrome or Chromium browser programmatically. You can navigate to web pages, interact with elements, and perform various actions without any user interface.
  • Page manipulation: With PuppeteerSharp, you can manipulate web pages by injecting custom JavaScript code, changing styles, filling forms, clicking buttons, and much more.
  • Screenshot generation: PuppeteerSharp enables you to capture screenshots of web pages or specific elements on a page. This can be useful for creating website thumbnails, generating documentation, or monitoring changes on a website.
  • PDF generation: You can use PuppeteerSharp to generate PDF files from web pages. This feature is handy for generating printable reports, invoices, or any other content that needs to be presented in a document format.
  • Web scraping: PuppeteerSharp makes it easy to scrape data from websites. You can extract text, HTML, attributes, or even perform complex operations like crawling multiple pages or following links.
  • Automated testing: PuppeteerSharp is a valuable tool for automating browser tests. You can simulate user interactions, validate page content, and perform assertions to ensure that your web application behaves correctly.

Getting Started with PuppeteerSharp

To start using PuppeteerSharp in your C# projects, you need to install the library via NuGet. Open your project in Visual Studio and search for the PuppeteerSharp package in the NuGet Package Manager. Once installed, you can import the PuppeteerSharp namespace in your code files.

Here’s a simple example that demonstrates how to launch a headless browser and navigate to a web page:

using PuppeteerSharp;

public class Program
 public static async Task Main()
 await new BrowserFetcher().DownloadAsync(BrowserFetcher.DefaultRevision);
 using (var browser = await Puppeteer.LaunchAsync(new LaunchOptions { Headless = true }))
 var page = await browser.NewPageAsync();
 await page.GoToAsync("https://example.com");
 // Perform further actions

In this code snippet, we first download the appropriate version of the headless Chrome or Chromium browser. Then, we launch the browser and create a new page. Finally, we navigate to the desired web page and perform any additional actions we need.


PuppeteerSharp is a powerful library for browser automation in C#. Its wide range of features, such as headless browser automation, page manipulation, screenshot and PDF generation, web scraping, and automated testing, make it a versatile tool for various tasks. If you are a C# developer looking to automate browser-related tasks, PuppeteerSharp can be a valuable addition to your toolkit.
