• One API for web and native mobile, which is rare and genuinely useful if you ship both.
• Vendor-neutral: swap between local, grid and any device cloud by changing config.
• Mature plugin ecosystem for reporting, visual testing and accessibility.

• 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.

• Configuration-heavy compared to Playwright; the wdio.conf.js file becomes a project of its own.
• Inherits WebDriver's flakiness characteristics when used in WebDriver mode.
• Smaller community than Playwright or Cypress, so obscure problems take longer to solve.

• 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.

JavaScript teams that need one framework covering both web and native mobile.

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