puppeteer features and specs

  • Headless Browsing
    Puppeteer allows headless browsing, which means you can automate and test web applications without opening a browser user interface, resulting in faster execution and lower resource usage.
  • Full Browser Control
    Enables full control over Chrome or Chromium browsers, allowing for comprehensive browser testing and automation, including taking screenshots, generating PDFs, and capturing web pages.
  • Rich API
    Offers a rich set of APIs that can control browsers, manage cookies, intercept network requests, and handle various browser events, making it versatile for different use cases.
  • Active Community
    Highly active open-source community with regular updates and a plethora of plugins and extensions, providing robust support and continuous improvements.
  • Compatibility
    Supports the latest JavaScript features and works seamlessly with popular libraries and frameworks, providing a modern development experience.

Possible disadvantages of puppeteer

  • Restricted to Chrome/Chromium
    Puppeteer is primarily designed to work with Chrome and Chromium browsers, limiting cross-browser testing capabilities compared to other tools that support multiple browsers.
  • Resource Intensive
    Running multiple instances of headless browsers can be resource-intensive in terms of CPU and memory usage, potentially affecting performance on limited hardware.
  • Learning Curve
    Requires some learning curve for developers unfamiliar with browser automation or the Puppeteer API, making initial setup and usage potentially time-consuming.
  • Lacks JavaScript Redaction
    Unlike some other tools, Puppeteer does not natively support JavaScript error redaction, which means developers must manage error handling and debugging themselves.
  • Not Ideal for GUI Tests
    Since Puppeteer is headless by default, it might not be ideal for GUI end-to-end tests that require visual validation, requiring additional tools or configurations to enable full browser displays.

User CSS features and specs

  • Customization
    User CSS allows for extensive customization of the appearance of websites, enabling users to tailor styles to their preferences or needs.
  • Accessibility
    Custom styles can improve accessibility by enhancing contrast, increasing font sizes, or adjusting layouts to make content more readable for individuals with visual impairments.
  • Consistency
    It can create a consistent look and feel across different websites by applying a personalized style sheet, which is beneficial for users who value uniformity.
  • Ad Blocking
    User CSS can be used to hide unwanted elements like advertisements or pop-ups, creating a cleaner browsing experience.
  • Focus on Content
    Users can modify the display to focus on content they deem important by hiding or de-emphasizing less relevant elements.

Possible disadvantages of User CSS

  • Maintenance
    User CSS scripts need regular updates and maintenance, as changes to website structures, class names, or IDs can break the applied styles.
  • Compatibility Issues
    Custom styles may not render correctly across different devices or browsers, leading to inconsistencies in how content is viewed.
  • Complexity
    For non-technical users, creating and managing User CSS can be complex and daunting without knowledge of CSS.
  • Website Functionality
    Incorrect or overly aggressive styling can inadvertently break website functionality or usability by hiding functional elements such as navigation or interactive components.
  • Performance
    Applying User CSS can affect the loading performance of websites, especially if the styles are extensive or poorly optimized.

Top Selenium Alternatives
Puppeteer offers more direct and tighter integration with Chrome or Chromium through the DevTools Protocol, unlike Selenium which abstracts the browser interaction through WebDriver, making it more versatile across different browsers but potentially less optimized for specific browser internals like those Puppeteer accesses in Chrome.

Best Data Scraping Tools
It is completely free. Puppeteer is well backed and supported by Google Chrome and hence replacing Selenium and PhantomJS. It automatically installs an efficient, compatible Chromium binary in its setup, therefore reducing the burden of keeping track on your browser.

Puppeteer vs Selenium
If you're looking for a better alternative, try Endtest. It has Puppeteer's speed, it supports Selenium's browsers AND it has all the features that they're missing.

Introduction to Headless Browser Testing
The Puppeteer API can be used to take screenshots, create PDFs, navigate pages, and fetch information from pages. We’ll write some example code to see Puppeteer in action.

  • Top React Testing Libraries in 2025
    Puppeteer is a headless browser automation tool built on Chromium. It allows developers to simulate user interactions, capture screenshots, and perform UI tests with a high degree of accuracy. Puppeteer is particularly useful for testing cross-browser compatibility and visual elements in React applications. Its robust API enables precise control over browser actions, making it a valuable tool for UI testing and... - Source: dev.to / about 2 months ago
  • End-to-End SEO Testing with Playwright and Lighthouse
    Vitest is a next-generation JavaScript testing framework powered by Vite. It’s an excellent alternative to Jest, offering native TypeScript support, a fast setup, and solid performance. However, while it has an experimental headless browser, it’s not ideal for advanced scenarios like running SEO audits in CI/CD pipelines. Instead, we can pair Vitest with Pupetter, a more mature tool for headless browser automation. - Source: dev.to / 2 months ago
  • The Puppeteer Language Experiment
    This project tests how the browser language can be changed with Puppeteer. It implements multiple options to set the language of Chrome and checks each option against BrowserLeaks to see how it affected the JavaScript proeprties and HTTP headers available by the browser. For more information, see my article The Puppeteer Language Experiment on DEV.to. - Source: dev.to / about 1 year ago
  • Scrapy Vs. Crawlee
    In Crawlee, you can scrape JavaScript rendered websites using the built-in headless Puppeteer and Playwright browsers. It is important to note that, by default, Crawlee scrapes in headless mode. If you don't want headless, then just set headless: false. - Source: dev.to / about 1 year ago
