WebdriverIO 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
- 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.
Limitations
- 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.
Best for
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.
All of these integrate with: GitHub Actions.
