The short version

  • Only Puppeteer has a free tier, so it costs nothing to try first.
  • Each has a real cost: Puppeteer chrome and Firefox only, with no Safari or WebKit story; Sauce Labs every published tier includes only a single parallel test session by default, so any team wanting to run multiple tests simultaneously needs to negotiate additional parallel sessions, which is not transparently priced on the public page.
  • They diverge on capability: Puppeteer covers DevTools Protocol, Sauce Labs covers Real device cloud.
  • Prices and features above were last checked on 1 September 2026.

  • Scraping sites that require JavaScript executionnot Sauce Labs
  • Automating browser tasks where a full test framework is unnecessarynot Sauce Labs

Sauce Labs

  • A QA team running Selenium or Appium test suites that needs cloud device and browser coverage without maintaining a physical labnot Puppeteer
  • A team wanting manual live testing sessions on real devices for exploratory or accessibility testingnot Puppeteer
  • An organisation needing video, screenshot and log capture on every automated test run for debugging flaky failuresnot Puppeteer
  • An enterprise wanting AI-assisted test authoring and insights alongside device cloud executionnot 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

Sauce Labs

  • Every published tier includes only a single parallel test session by default, so any team wanting to run multiple tests simultaneously needs to negotiate additional parallel sessions, which is not transparently priced on the public page.
  • Enterprise pricing, where AI agents and SSO live, is quote-only, so the most capability-rich tier loses the pricing transparency of the lower tiers.
  • It competes directly with BrowserStack on almost identical device cloud fundamentals, and the two vendors leapfrog each other on device inventory and pricing often enough that a comparison made today can be outdated within a year.
  • Real device availability for less common device and OS combinations can queue during peak usage, which affects CI pipelines that expect on-demand execution.
  • The unlimited-minutes model rewards teams that run tests constantly and penalises smaller teams paying the same base price for occasional, low-volume use.

Answered from the vendors’ own pages

Puppeteer: Is Puppeteer free?

Yes, open source from the Chrome team.

Sauce Labs: Is Sauce Labs priced by testing minutes?

No, every published plan includes unlimited testing minutes and unlimited users; the pricing lever is the number of parallel test sessions and device category.

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.

Sauce Labs: How does it differ from BrowserStack?

Both offer equivalent real and virtual device cloud testing for Selenium and Appium; differences are mainly in device inventory specifics, parallel session pricing and AI feature rollout, which change often enough to need a current comparison.

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.

Sauce Labs: Do I need Appium or Selenium separately?

Yes, Sauce Labs provides the device and browser infrastructure; test scripts are still written against the open source Selenium or Appium frameworks.
