7 PhantomJS Alternatives Every Developer Must Know

PhantomJS is a renowned headless browser among JavaScript developers for its automated testing and web scraping capabilities. Its API allows you to simulate browser interactions and render JavaScript, but its discontinued development raised the need for a PhantomJS alternative.

Here's a quick comparison table of the most popular options:

You'll get an overview of each of these PhantomJS alternatives. Here's a quick access to the takeaways:

• Best PhantomJS alternatives overall.
• Top PhantomJS alternatives by language.

But before we dive into that, let's learn some important background.

Why Look for a PhantomJS Alternative?

PhantomJS emerged as one of the first mainstream headless browsers for automated testing and web scraping in new areas. However, Vitaly Slobodin, the single maintainer of the open-source project, announced his decision to step down, and the PhantomJS' development came to an abrupt end.

That wasn't surprising as the project had only a few contributors to deal with the numerous bug reports and feature requests received. That meant users had to endure prolonged release cycles, influencing the need for other options like the then newly-released Headless Chrome and Puppeteer.

1. ZenRows: The Web Scraping Key

ZenRows is a web scraping API with full headless browser functionality and everything you need to avoid getting blocked while web scraping. Its anti-bot bypass prowess separates it from any PhantomJs alternative, ensuring you retrieve your desired data without worrying about anti-scraping techniques. 

Additionally, ZenRows' ease of use and support for all programming languages make it a great choice. That's evident in its developer adoption rate, which experiences a monthly increase of 27.4%. You only need to make your requests through the ZenRows API to enjoy its functionalities.
