Fight!

Popularity

Puppeteer is more popular and widely used compared to CasperJS. Puppeteer has gained significant popularity due to its powerful features and extensive documentation.

Functionality

Both CasperJS and Puppeteer are headless browser automation tools, but they have some differences in terms of functionality. CasperJS is built on top of PhantomJS and provides a higher-level API for browser automation. Puppeteer, on the other hand, is a Node.js library developed by the Chrome team and provides a more modern and powerful API for controlling Chrome or Chromium browsers.

Browser Support

CasperJS supports multiple browsers, including PhantomJS, SlimerJS, and SlimerJS2. Puppeteer, on the other hand, is specifically designed for Chrome or Chromium browsers.

Flexibility

Puppeteer offers more flexibility and control over the browser environment. It allows you to manipulate the DOM, take screenshots, generate PDFs, and perform various browser automation tasks. CasperJS also provides similar capabilities but may have some limitations compared to Puppeteer.

Documentation

Puppeteer has extensive and well-maintained documentation, including examples and API references. CasperJS documentation is also available but may not be as comprehensive as Puppeteer's.

Maintenance

Puppeteer is actively maintained by the Chrome team, ensuring regular updates and bug fixes. CasperJS, on the other hand, has seen a decline in maintenance and updates in recent years, with the last major release being in 2017. This may indicate that Puppeteer is a more future-proof and actively developed library.
