What is Puppeteer?
A Node.js library from the Chrome team that drives Chromium over the DevTools Protocol, used for scraping, screenshots, PDF generation, and headless testing.
Puppeteer launches a Chromium instance (headless by default, optionally headed) and gives JavaScript code direct access to the same control surface Chrome's DevTools uses. You can navigate to URLs, evaluate scripts inside the page, intercept network requests, capture screenshots, generate PDFs, and pull the rendered DOM out as HTML. Because it talks DevTools Protocol natively, Puppeteer is faster and exposes more low-level hooks than WebDriver-based tools.
For brand-data use cases, Puppeteer is a workhorse. Rendering a page above the fold for a screenshot, waiting for a logo image to load before extracting its src, or grabbing the post-hydration HTML of a Next.js app are all one or two API calls. Stealth plugins (puppeteer-extra-plugin-stealth) patch over the obvious automation tells, which buys headroom against anti-bot vendors before you have to escalate to residential proxies.
The main tradeoffs versus Playwright are scope and ergonomics. Puppeteer is Chromium-only and has fewer built-in waits, so you write more glue code. Playwright covers Chromium, Firefox, and WebKit with a cleaner API. If you only need Chrome and the team is already on Node, Puppeteer is the lighter dependency.

- Generating PDF invoices from an HTML template at request time
- Capturing a full-page screenshot of every URL in a sitemap
- Scraping product detail pages that lazy-load images on scroll
