Control Chrome and Firefox programmatically with a high-level JavaScript API
Puppeteer offers a high-level JavaScript API to automate Chrome or Firefox via DevTools Protocol, supporting headless operation and full browser control for testing and scraping.
Puppeteer is a TypeScript‑written library that gives developers a concise, promise‑based API to drive Chrome or Firefox browsers through the DevTools Protocol or WebDriver BiDi. By default it launches browsers in headless mode, making it ideal for CI pipelines, but it also supports full UI operation when needed. The library handles browser binary management— downloads a matching Chromium build, while lets you connect to an existing browser, keeping the footprint small.
puppeteerpuppeteer-coreWith Puppeteer you can script navigation, manipulate the DOM, capture screenshots, generate PDFs, and extract data from pages that rely on client‑side JavaScript. Its TypeScript definitions provide strong typing for IDE assistance. Installation is a single npm i puppeteer (or puppeteer-core) command, after which the library can be used in any Node.js environment, including Docker containers and serverless functions. The extensive documentation and active community help teams integrate browser automation into testing suites, scraping pipelines, and content generation workflows.
When teams consider Puppeteer, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Automated regression testing
Detect UI changes across releases with reliable screenshot and DOM comparisons
Dynamic data extraction
Scrape content from pages that rely on client‑side rendering
PDF generation
Create printable PDFs from web pages with exact layout fidelity
Visual monitoring
Capture pixel‑perfect screenshots for dashboard reporting
Chrome (and Chromium) are fully supported; Firefox support is available via the DevTools Protocol.
Use the `puppeteer-core` package, which provides the API without bundling a browser binary.
Yes, set the `headless` launch option to `false` to run in headful mode.
Absolutely; the library includes built‑in TypeScript definitions for full type safety.
