Puppeteer multiple browsers or pages

Question

I am trying to crawl about 50 pages with puppeteer, and right now I am doing one after another in a single browser, single page. To make this faster, should I use more pages or more browsers?

Answer 1

I don't think you want to use either:

• Using more pages isn't great because your browser will build up a history. This may not be what you intend.
• Using more browsers isn't great because creating a new browser is a fairly expensive operation.

I think you want to use Browser Contexts. Think of a browser context as an incognito window - you can open it quickly, but it doesn't share history, cookies, etc. with other contexts.
