CasperJS vs PhantomJS vs Serverless Chrome: What are the differences?

In web development, tools like CasperJS, PhantomJS, and Serverless Chrome are often used for testing and automation. Here, we will discuss the key differences between these tools.

  1. Execution Environment: CasperJS is built on top of PhantomJS, providing a higher-level API for easier testing and automation. PhantomJS, on the other hand, is a standalone headless browser, which can be used independently for a variety of tasks. Serverless Chrome is a version of headless Chrome that can be deployed in a serverless environment, allowing for efficient scaling and cost-effective usage.

  2. Language Support: CasperJS supports JavaScript and CoffeeScript for writing test scripts. PhantomJS also works with JavaScript but has broader compatibility with various scripting languages. Serverless Chrome supports JavaScript as well but emphasizes compatibility with Chrome DevTools Protocol for debugging and interaction.

  3. Maintenance and Support: CasperJS and PhantomJS have been largely static in terms of updates and maintenance due to the development halt. Serverless Chrome, being based on the actively maintained headless Chrome project, receives regular updates and improvements, ensuring compatibility with the latest web technologies.

  4. Performance and Scalability: CasperJS and PhantomJS may face performance limitations when handling a large number of concurrent tasks due to their architecture. Serverless Chrome, being able to scale automatically in a cloud environment, offers better performance and scalability for tasks requiring dynamic resource allocation.

  5. Integration with CI/CD: While CasperJS and PhantomJS can be integrated with continuous integration and continuous deployment tools, Serverless Chrome provides seamless integration with serverless architectures, making it more suitable for automated testing and deployment pipelines.

  6. Resource Management: CasperJS and PhantomJS may require manual configuration and optimization for efficient resource management. Serverless Chrome, being designed for dynamic resource allocation in a serverless environment, streamlines resource management and reduces the need for manual intervention.

In Summary, CasperJS offers a high-level API for testing and automation, PhantomJS is a standalone headless browser with broader language support, and Serverless Chrome excels in scalability and resource management in a serverless environment.

Advice on PhantomJS, CasperJS, Serverless Chrome

Needs advice

I am using Node 12 for server scripting and have a function to generate PDF and send it to a browser. Currently, we are using PhantomJS to generate a PDF. Some web post shows that we can achieve PDF generation using Puppeteer. I was a bit confused. Should we move to puppeteerJS? Which one is better with NodeJS for generating PDF?

CasperJS
CasperJS
Serverless Chrome
Serverless Chrome

PhantomJS is a headless WebKit scriptable with JavaScript. It is used by hundreds of developers and dozens of organizations for web-related development workflow.

CasperJS is a browser navigation scripting & testing utility written in Javascript for PhantomJS or SlimerJS.

The aim of this project is to provide the scaffolding for using Headless Chrome during a serverless function invocation. Serverless Chrome takes care of building and bundling the Chrome binaries and making sure Chrome is running when your serverless function executes. In addition, this project also provides a few "example" handlers for common patterns (e.g. taking a screenshot of a page, printing to PDF, some scraping, etc.)

Multiplatform, available on major operating systems: Windows, Mac OS X, Linux, and other Unices; Fast and native implementation of web standards: DOM, CSS, JavaScript, Canvas, and SVG. No emulation; Pure headless (no X11) on Linux, ideal for continuous integration systems. Also runs on Amazon EC2, Heroku, and Iron.io; Easy to install: Download, unpack, and start having fun in just 5 minutes

What are some alternatives to PhantomJS, CasperJS, Serverless Chrome?

Playwright

Playwright

It is a Node library to automate the Chromium, WebKit and Firefox browsers with a single API. It enables cross-browser web automation that is ever-green, capable, reliable and fast.

Puppeteer

Puppeteer

Puppeteer is a Node library which provides a high-level API to control headless Chrome over the DevTools Protocol. It can also be configured to use full (non-headless) Chrome.

HeadlessTesting

HeadlessTesting

Headless Browser Cloud for Developers. Connect your Puppeteer and Playwright scripts to our Cloud. Automated Browser Testing with Puppeteer and Playwright in the Cloud.

jsdom

jsdom

It is a pure-JavaScript implementation of many web standards, notably the WHATWG DOM and HTML Standards, for use with Node.js. In general, the goal of the project is to emulate enough of a subset of a web browser to be useful for testing and scraping real-world web applications.

Splash

Splash

It is a headless browser that executes JavaScript for people crawling websites. It is open source and fully integrated with Scrapy and Portia. You can also use its API to integrate with any project that needs to render JavaScript pages.

Chromeless

Chromeless

Chrome automation made simple. Runs locally or headless on AWS Lambda.

SlimerJS
