CasperJS vs Serverless Chrome: What are the differences?
Developers describe CasperJS as "Navigation scripting & testing for PhantomJS and SlimerJS". CasperJS is a browser navigation scripting & testing utility written in Javascript for PhantomJS or SlimerJS. On the other hand, Serverless Chrome is detailed as "Headless Chrome on AWS Lambda". 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.).
CasperJS and Serverless Chrome can be primarily classified as "Headless Browsers" tools.
CasperJS and Serverless Chrome are both open source tools. It seems that CasperJS with 7.3K GitHub stars and 1.06K forks on GitHub has more adoption than Serverless Chrome with 1.95K GitHub stars and 192 GitHub forks.
