• 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.

• Shared vocabulary between product, QA and engineering when the practice is actually followed.
• Scenarios double as living documentation that stays honest because it executes.
• Available in every major language.

• 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.

• Almost always adopted as a syntax rather than a collaboration practice, at which point it is pure overhead on top of your real tests.
• The step-definition layer is a second codebase to maintain and refactor.
• Gherkin obscures technical detail that developers need when a test fails.

Automation jobs that are not tests, or Chrome-only tooling where you want minimal dependencies.

Teams genuinely practising BDD with three-amigos sessions, not teams who just want prettier test names.
