Puppeteer
Puppeteer is a Node.js library that provides a high-level API to control Chrome or Firefox via the DevTools Protocol or WebDriver BiDi. It can run browsers in headless or headed modes, allowing automation of page interactions, navigation, and content extraction. The library is maintained by the Chrome DevTools team and is widely used for browser automation, testing, and scraping. Puppeteer supports features such as generating screenshots and PDFs, automating form submissions and UI interactions, capturing performance traces, and testing modern web applications including single-page apps. It can also emulate devices, intercept network requests, and run in environments like CI systems. With its extensive API, developers can automate complex browser tasks with concise JavaScript code. The project is open source under Apache License 2.0 and is actively developed on GitHub, with frequent releases and a large community of contributors. It integrates with popular testing frameworks and can be used alongside other browser automation tools.
