• The human fallback covers scenarios automation genuinely cannot reach.
• Anyone on the team can author a test.
• Results in minutes, integrated into the deployment pipeline.

• 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.

• Human runs get expensive quickly at any real frequency.
• Human testers lack product context, so results need interpretation.
• Web only.

• 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.

Teams that need broad release-gate coverage including flows nobody wants to automate.

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