Selenium WebDriver vs Puppeteer
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Strengths
- The widest language and browser support of anything in the category, including legacy browser versions.
- A W3C standard, so it will outlive any single vendor. Skills transfer between employers.
- Every device cloud speaks Selenium, which keeps you portable between vendors.
- Small, fast, and very well documented for Chrome-specific work.
- First-class access to the Chrome DevTools protocol for performance tracing and coverage.
- Excellent at non-test jobs: PDF rendering, screenshots, scraping.
Limitations
- No built-in waiting strategy, reporting, parallelism or assertions — expect to assemble and maintain a framework around it.
- Explicit waits are your problem, and getting them wrong is the number one source of flake in real Selenium suites.
- Out-of-process communication makes it slower than Playwright or Cypress.
- No test runner, assertions, retries or reporting — you assemble all of it.
- Chrome and Firefox only; no WebKit.
- For E2E testing specifically, Playwright is a strict superset. Choose Puppeteer only when you want a minimal automation library.
Best for
Enterprises with polyglot teams, legacy browser requirements, or an existing grid investment.
Automation jobs that are not tests, or Chrome-only tooling where you want minimal dependencies.
All of these integrate with: Docker.
