Compare CasperJS to these popular alternatives based on real-world usage and developer feedback.

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

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.

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.

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.

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

It allows you to manipulate a web page with an external Javascript script: opening a webpage, clicking on links, modifying the content... It is useful to do functional tests, page automation, network monitoring, screen capture etc.

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.)
