Key differences between Puppeteer and Selenium

Below are the key criteria that set Puppeteer and Selenium apart.

Language support

Puppeteer is predominantly a JavaScript-centric tool. It is designed to work seamlessly with Node.js, a JavaScript runtime, and allows users to harness the power of JavaScript to script their automation tasks. JavaScript's asynchronous nature aligns well with Puppeteer's capabilities, enabling developers to handle asynchronous operations efficiently.

While Puppeteer itself is JavaScript-centric, it's important to note that Puppeteer scripts can be executed in various environments that support Node.js. This flexibility allows developers to integrate Puppeteer into their projects, whether they are building web applications using JavaScript, TypeScript, or even leveraging Node.js within a broader technology stack.

Selenium, in contrast, supports multiple programming languages. The Selenium WebDriver bindings are available for languages such as Java, Python, C#, Ruby, and JavaScript. This wide range of language support makes Selenium an attractive choice for teams working in diverse technology stacks, as they can choose the language that aligns best with their expertise and project requirements. 

Here's a brief overview of Selenium's language support:

Java: Selenium has robust bindings for Java, making it a preferred choice for many enterprises and Java-centric development environments.

Python: With Selenium's Python bindings, developers can leverage the simplicity and readability of Python to automate their web testing and scraping tasks.

C#: Selenium supports C# through its WebDriver bindings, catering to developers using Microsoft technologies and the .NET framework.

Ruby: Selenium's support for Ruby enables developers in the Ruby ecosystem to seamlessly integrate automated testing into their workflows.

JavaScript: Similar to Puppeteer, Selenium provides JavaScript bindings, allowing developers to write automation scripts using JavaScript and Node.js.

Browser support

Puppeteer is specifically developed to control and automate Chromium-based browsers, providing an optimized experience for tasks such as web scraping, generating screenshots, and creating PDFs.

In contrast, Selenium provides cross-browser compatibility, supporting a wide array of popular web browsers. Selenium WebDriver, the core component for browser automation, facilitates interactions with different browsers, making it a versatile choice for projects requiring compatibility across diverse environments. Supported browsers are Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, Opera, and Internet Explorer.
