Selenium
Testing
Browser automation framework and the W3C WebDriver standard
- From
- Free
- Rated
- -
The short version
- Each has a real cost: Selenium flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically; Puppeteer chrome and Firefox only, with no Safari or WebKit story
- They diverge on capability: Selenium covers W3C WebDriver, Puppeteer covers DevTools Protocol.
Where they differ
Only the attributes on which Selenium and Puppeteer actually diverge.
Identical on both: starting price (Free), pricing model (Open source, no licence fee), free tier (Yes), user rating (Not yet rated), category (Testing).

What people use each for
The jobs each tool is most often brought in to do.
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
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
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
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

Answered from the vendors’ own pages
Selenium: Is Selenium free?
Yes, open source with no licence fee. Paid costs come from grid infrastructure or services like BrowserStack.
Puppeteer: Is Puppeteer free?
Yes, open source from the Chrome team.
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: 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: 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.
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.
