Fight!

Browser Support

Puppeteer is developed by Google and primarily works with the Chromium browser. It provides better support for modern web features and has good compatibility with Chrome. SlimerJS, on the other hand, is based on Gecko (Firefox) and may have better compatibility with Firefox-specific features.

Performance

Puppeteer is known for its speed and performance, especially when it comes to headless browser automation tasks. It is optimized for performance and resource usage. SlimerJS, while capable, may not be as performant as Puppeteer in certain scenarios.

Ease of Use

Puppeteer has a more user-friendly API and is easier to get started with, especially for beginners. It provides a high-level API for common tasks and has good documentation. SlimerJS, while powerful, may have a steeper learning curve and a less intuitive API.

Community and Support

Puppeteer has a larger community and is actively maintained by Google, which ensures regular updates and support. SlimerJS, while still maintained, may not have as large of a community or as frequent updates as Puppeteer.

Flexibility

Puppeteer is more flexible in terms of the environments it can run in and the tasks it can perform. It supports headless mode, browser extensions, and has good debugging capabilities. SlimerJS, while versatile, may not offer the same level of flexibility as Puppeteer.
