Web scraping often depends on browsing automation tools to retrieve and interact with website content. Two of the most powerful tools are Puppeteer and Playwright. Neither of them was originally designed for scraping, but their ability to control the browsers in both headful and non-headless modes makes them invaluable for data extraction tasks. Many developers become confused about which library to choose for their web scraping project. So, we will go deeper into Playwright vs. Puppeteer.

In this guide, we will compare the strengths, performances, ease of use, CAPTCHA handling, and headless and headful modes of both. 

What is Puppeteer?

Launched in 2017, Puppeteer is an open-source Node.js library that provides APIs to control browsers based on Chrome and Chromium. It is developed and maintained by Google itself, allowing it to run in both headful and headless mode. Puppeteer doesn’t have any built-in testing features, but it easily integrates with strong JavaScript testing frameworks. Major features of Puppeteer include screenshot testing, performance testing, web automation, and scraping.

One of its features is seamless integration with Chrome. Puppeteer supports features like capturing screenshots, generating PDFs, and using built-in selectors like XPath to locate elements within a webpage.

While being good at handling Chromium-based browsers, Puppeteer has limited support for cross-browser compatibility. However, it has a larger community and more resources, as it was released way back in 2017.

What are the Advantages of Puppeteer?

Some advantages that Puppeteer offers are:

• Efficient APIs: Puppeteer provides a simple and easy-to-use API that makes it easy to write and maintain test scripts.
• Headless browsing: Puppeteer can run a browser in headless mode, which means it can test and run scripts without the need for a graphical user interface, making it quite efficient and faster.
• Multiple browsers support: Puppeteer can be used to automate different browsers, such as Chrome, Firefox, and Safari.
• Enhance features: Puppeteer allows you to capture screenshots and generate PDFs of the webpages for testing purposes.
• Easier testing: Puppeteer can be used for testing by collaborating with other tools like Mocha to run tests in parallel, making testing a lot faster and less time-consuming.
• Easy setup: It is very easy to configure and set up.

What are the Disadvantages of Puppeteer?

Puppeteer offers with many advantages, but it also has some drawbacks.

• Older versions: Puppeteer can automate the scripts on many browsers, but it only supports the latest version of each browser. It can be a hindrance if you need to run on older versions.
• Web-based: Puppeteer is basically designed for web-based applications; it may not be suitable for testing desktop and mobile applications.
• Speed: Puppeteer’s speed gets affected a lot if you are working on complex web applications, especially when the page consists of a lot of dynamic content.
• Understanding of Node.js: As Puppeteer is part of Node.js, which means to work with it effectively, one has to have a proper knowledge and understanding of Node.js. 
• Built-in tools: Puppeteer lacks built-in testing tools, so it may require additional tools to test a framework to be effective.

What is Playwright?

Playwright is an open-source library developed by Microsoft in 2020. It provides a unified API that has simplified control over Chromium, Firefox, and WebKit. It also supports end-to-end testing across major operating systems (Linux, Windows, macOS) and integrates seamlessly with CI/CD tools like Azure.

Playwright supports multiple languages, like Java, Python, and .NET. It becomes handy in performing cross-browser testing on complex applications and offers wide coverage with such high speed.

Playwright is designed to handle dynamic web pages efficiently. It supports automatic waiting, which ensures that elements become actionable before interaction occurs. It provides features like taking screenshots, generating PDFs, and recording videos for test sessions. It can also monitor and intercept the network requests.

One of the biggest advantage Playwright has is its built-in testing features that allow developers to run applications in different environments, including mobile devices, through emulation.

However, despite all these things, it has a smaller community and fewer resources compared to Puppeteer.

What are the Advantages of Playwright?

Playwright comes with these advantages:

• Cross-browser support: Playwright supports many major browsers, such as Chromium, Firefox, and WebKit, for testing.
• Multi-language support: It is not bound to only one language. It offers SDKs for Java, Node.js, Typescript, C#, and Python, making it accessible for each language.
• Efficient Automation: Playwright lets elements of a web page be loaded fully before interactions, which drastically enhances testing reliability. 
• Parallel testing: It allows scripts to run tests in parallel, which significantly reduces test execution time, making it ideal for CI/CD pipelines.
• Headless and Headful modes: It offers both modes for running tests, making it suitable for both CI and debugging.
• Network control: Playwright provides strong network control features, allowing you to intercept and modify requests to adjust according to different scenarios.

What are the Disadvantages of Playwright?

The disadvantages of Playwright are:

• Resource-heavy: Playwright can be resource-intensive while running multiple browser tests in parallel, which can heavily affect the performance.
• Third-party integrations: Compared to Puppeteer, Playwright has very few integrations with third-party services.
• Community: Although growing, the Playwright community is smaller compared to Puppeteer, which affects the availability of plugins and extensions.
• Maintenance: As it is new compared to Puppeteer, it gets more often updates, adding new features, making it harder for developers to manage it, especially for projects made in older versions.
• Mobile testing: It supports mobile emulation, enabling it to test on different screen sizes and devices directly within a desktop environment.
• Large installation size: The installation package includes multiple files for different browsers, which takes up much disk space and setup time.

Puppeteer vs. Playwright: What are the Differences Between Them?

Web Scraping

Web scraping is an automated process of extracting public data from websites. In terms of web scraping, both libraries have extraordinary scraping capabilities. Both can automate web page interactions, such as filling out forms, scrolling through buttons, clicking on buttons, and extracting target data.

The main issues with web scraping is bot detection, resulting in websites detecting from websites. It usually happens when an automated script clicks buttons very fast, which sends a vast amount of requests to the host server. So, we have to add breaks to avoid this.

Playwright provides built-in functionality for this, which is called auto-wait functionality. It imitates a human by waiting a certain amount of time after sending a request to the server, and also waits for an element to be visible and appear in the DOM.

Puppeteer doesn’t have this built-in function. We have to set up timers manually for elements to load properly. 

For interruption-free web scraping, third-party services such as paid proxy providers are required to bypass CAPTCHA by using advanced browser fingerprinting.

Proxies enhance the performance of both libraries by bypassing the security measures. Residential proxies with real device-assigned IPs mimic real users and help you prevent detection. Datacenter proxies offer speed, but they get detected easily. 

Playwright offers cross-browsing support, helping you in projects where you need to scrape more than one page at a time, making Playwright your best choice in such a scenario.

If you want to know more about proxies and how they work, refer to our guide.

Popularity

Puppeteer is older and more popular than Playwright. Playwright’s recent sudden rise in popularity is due to its cross-browser support, multi-language compatibility, and auto-waiting features. In comparison, Puppeteer is limited in both language and platform support. So, these features make Playwright a preferred tool for web scraping, testing, and automation.

Handling CAPTCHA

The most common challenged faced during web automation is bot detection, which can lead to blocking and CAPTCHAs. Playwright’s feature of waiting for elements to be loaded before interacting with them makes the browser think it’s an actual user interacting with it, drastically reducing the chances of detection. On the other side, Puppeteer requires manual setup of timers, which can be more detectable.

Performance Testing and Framework Integration

Both tools have built-in integration capabilities with popular testing frameworks for performance testing. Playwright’s multi-context browsing and device emulation make it perfect for testing across different browsers and devices. Puppeteer, on the other hand, remains the best choice for Chromium-based testing.

Community Support and Resources

Puppeteer has an ecosystem with extensive documentation and a large number of resources with a vast community, making it easier for developers to find solutions to new problems. And it is actively maintained by the Chrome team itself.

Playwright, being newer, has its own growing community, but it has a very fewer resources compared to Puppeteer.

Well, considering all the facts, Puppeteer lacks the edge when it comes to web scraping, making Playwright would be the obvious choice for most developers and users.
