Web scraping with JavaScript and looking for a comparison between PhantomJs vs. Puppeteer?

This article will unravel the differences between Puppeteer and PhantomJS and conclude the best one for you.

> **Info**

> The development of [PhantomJS](https://github.com/ariya/phantomjs) has been suspended since 2018 because it lacked active contribution. PhantomJS 2.1.1 remains the last stable release till further notice.

## PhantomJS vs. Puppeteer: Which Is Best?
PhantomJS is a **discontinued headless browser** with a JavaScript API for automating web pages. It has an independent JavaScript runtime and doesn't depend on Node.js only.

Puppeteer is an **actively developed Node.js library** for automating Chrome and Chromium-based browsers. While PhantomJS is strictly headless, Puppeteer can run in headless or non-headless mode.

Puppeteer is superior to PhantomJS since its features are more recent. It's one of the [best headless browsers for web scraping](/blog/headless-browser-scraping), and it's the ideal choice if you want a feature-rich and updated tool to automate and scrape dynamic web pages more efficiently.

## Overview: PhantomJS vs. Puppeteer
Let's overview the comparison between PhantomJS and Puppeteer in the table below.

| Considerations           | Puppeteer                                               | PhantomJS                                               |
|--------------------------|---------------------------------------------------------|---------------------------------------------------------|
| Ease of use               | Straightforward with an easier learning curve           | Steeper learning curve                                   |
| Headless/non-headless support | Headless and non-headless modes are available         | Strictly headless                                        |
| Rendering engine          | Chrome's Blink engine                                   | WebKit engine                                            |
| HTTP requests             | Yes                                                     | Yes                                                     |
| Avoid getting blocked     | Proxy and header rotation, request limiting, Puppeteer Stealth plugin, Web scraping APIs | Proxy and header rotation, limited options to bypass detection |
| Community and Documentation | Well-documented with active community                   | Outdated documentation, community support dropped significantly after the discontinuation |
| Maintenance and upkeep    | Actively maintained                                     | Discontinued                                            |
| Runtime dependency        | Depends on Node.js                                      | Independent executable and Node.js                       |

## PhantomJS Review
PhantomJS provides a JavaScript API for automating headless browsers **based on the WebKit rendering engine**. Due to discontinuation, testers and scrapers now prefer to use [PhantomJS alternatives](/alternatives).

**👍 Pros of PhantomJS:**

*   Support for the WebKit engine extends browser compatibility.
*   Quick command line tools are available.
*   Flexibility to run as an independent executable or as a Node.js module.

**👎 Cons of PhantomJS:**

*   Discontinued.
*   Outdated documentation.
*   Inactive community.
*   Higher chances of getting blocked during scraping.
*   Steeper learning curve.
*   Limited integration with Chrome DevTools.
*   May not support modern JavaScript since there's no active development.
*   Strictly headless.
*   Support integration with testing frameworks is becoming less possible.

**👨‍💻 Best Use Cases for PhantomJS:**

*   General page automation.
*   Network monitoring.
*   Taking screenshots and converting web pages into PDFs.
*   Web scraping.

## Puppeteer Review
Puppeteer uses the Chome DevTools APIs to automate a real user's actions on a web page. [Puppeteer web scraping](/blog/puppeteer-web-scraping) is now a preferred choice among scrapers using JavaScript.

**👍 Pros of Puppeteer:**

*   Actively developed and more stable.
*   Well-documented.
*   Easier learning curve with an active community.
*   Anti-bot protection like [Puppeteer Stealth](/blog/puppeteer-stealth) is available to help [bypass WAF systems](/blog/waf-bypass) and avoid getting blocked.
*   Provides better integration with the Chrome DevTools.
*   More flexible with the ability to switch between headless and non-headless modes.
*   Supports modern JavaScript scripting with a simpler syntax.
*   Easily integrates with other testing frameworks, including Jest and Mocha.

**👎 Cons of Puppeteer:**

*   Limited to Chrome/Chromium browsers.
*   Strictly depends on the Node.js runtime.

**👨‍💻 Best Use Cases for Puppeteer:**

*   Automation testing.
*   Web scraping.
*   Taking screenshots and generating web page PDFs.
*   Performance monitoring.
*   Accessibility testing.

## Conclusion
After comparing PhantomJS vs. Puppeteer in the article, it's clear that Puppeteer stands out as the superior choice. It's actively developed, supports more use cases, and is well-documented. Additionally, Puppeteer is more adjustable to avoid anti-bot detection.
