The short version

  • Each has a real cost: Puppeteer chrome and Firefox only, with no Safari or WebKit story; Selenium flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically
  • They diverge on capability: Puppeteer covers DevTools Protocol, Selenium covers W3C WebDriver.
  • Prices and features above were last checked on 29 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Puppeteer

  • Generating PDFs or screenshots of rendered pages on a servernot Selenium
  • Scraping sites that require JavaScript executionnot Selenium
  • Automating browser tasks where a full test framework is unnecessarynot Selenium

Selenium

  • Cross-browser testing where Safari and legacy browsers must be coverednot Puppeteer
  • Teams whose test suites are written in Java or C# rather than JavaScriptnot Puppeteer
  • Distributing a large suite across a grid of machinesnot Puppeteer

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Puppeteer

  • Chrome and Firefox only, with no Safari or WebKit story
  • Not a test framework: assertions, retries and reporting need Jest or similar bolted on
  • Bundles a Chromium download, which makes installs large and awkward in constrained CI images

Selenium

  • Flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically
  • Setup involves drivers, versions and grid infrastructure that Playwright and Cypress bundle away
  • Slower to run than tools that talk to browsers over a debugging protocol rather than WebDriver

Answered from the vendors’ own pages

Puppeteer: Is Puppeteer free?

Yes, open source from the Chrome team.

Selenium: Is Selenium free?

Yes, open source with no licence fee. Paid costs come from grid infrastructure or services like BrowserStack.

Puppeteer: Puppeteer or Playwright?

Playwright came from the same original team, adds WebKit and Firefox support, automatic waiting and a test runner. Puppeteer stays a focused Chrome automation library, which is simpler if automation rather than testing is the goal.

Selenium: Selenium or Playwright?

Playwright handles waiting automatically and is faster to set up, which removes most flakiness complaints. Selenium wins on language breadth, browser coverage including Safari, and existing suites you already have.

Puppeteer: Can Puppeteer generate PDFs?

Yes, and it is one of the most common uses — rendering a page and printing it to PDF server-side.

Selenium: Is Selenium still relevant?

Yes. Its WebDriver protocol is a W3C standard implemented by every major browser, and very large existing suites are not rewritten cheaply.
