The short version

  • Each has a real cost: Puppeteer chrome and Firefox only, with no Safari or WebKit story; TestNG maintainership is concentrated around creator Cedric Beust rather than a broad team or foundation, which is a real continuity risk compared to JUnit's independent team or Jest's foundation backing.
  • They diverge on capability: Puppeteer covers DevTools Protocol, TestNG covers Test dependencies.
  • Prices and features above were last checked on 1 September 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 TestNG
  • Scraping sites that require JavaScript executionnot TestNG
  • Automating browser tasks where a full test framework is unnecessarynot TestNG

TestNG

  • A Java integration test suite that needs to skip dependent tests automatically when a prerequisite test failsnot Puppeteer
  • A team wanting XML-based suite configuration to manage large, grouped test suites without touching code for each runnot Puppeteer
  • A project needing native parallel test execution at the class or method level without adding a separate pluginnot Puppeteer
  • A Selenium-based UI test suite that uses TestNG as the underlying runner for grouping and parallelisationnot 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

TestNG

  • Maintainership is concentrated around creator Cedric Beust rather than a broad team or foundation, which is a real continuity risk compared to JUnit's independent team or Jest's foundation backing.
  • It is a smaller ecosystem than JUnit, so fewer third-party integrations, tutorials and Stack Overflow answers exist for edge cases.
  • XML-based suite configuration, while powerful, is an extra file and syntax to maintain alongside the codebase, which some teams find adds friction JUnit's more code-centric model avoids.
  • There is no commercial support tier or vendor relationship of any kind, unlike JUnit's OpenElements arrangement, so an enterprise wanting a support contract has no route to buy one.
  • Release cadence, while active, is slower and less frequent than JUnit 5's, since it depends on a much smaller pool of active maintainers.

Questions people ask

Is Puppeteer or TestNG better?
Neither clearly leads. Puppeteer starts at Free and TestNG at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Puppeteer or TestNG?
Puppeteer starts at Free and TestNG at Free.
Does Puppeteer or TestNG run on more platforms?
Both run on Linux, macOS, Windows, so platform support will not decide this one for you.

Both have a free tier, so you can try either at no cost before committing.
What is Puppeteer best used for?
Puppeteer is most often used for generating pdfs or screenshots of rendered pages on a server, scraping sites that require javascript execution, automating browser tasks where a full test framework is unnecessary. Of those, generating pdfs or screenshots of rendered pages on a server and scraping sites that require javascript execution are not what TestNG is typically brought in for.

Puppeteer covers DevTools Protocol, Headless by default, PDF and screenshots, Network interception. TestNG covers Test dependencies, XML suite configuration, Native parallel execution, Data providers.

Answered from the vendors’ own pages

Puppeteer: Is Puppeteer free?

Yes, open source from the Chrome team.

TestNG: Is TestNG still actively maintained in 2026?

Yes, it continues to receive releases in its 7.x line with support for current Java versions, though maintenance is concentrated around a small team led by its creator.

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.

TestNG: What does TestNG offer that JUnit does not?

Native test dependencies, XML-based suite configuration and built-in parallel execution without needing external plugins, all of which JUnit users typically add via separate libraries.

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.

TestNG: Is there a commercial support option for TestNG?

No, unlike JUnit there is no commercial support arrangement; support is purely community-based through GitHub.
