• 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.

• Zero setup: no drivers, no browser downloads, works on any installed browser including mobile Safari on a real phone.
• Automatic waiting and stable selectors with very little configuration.
• Genuinely simple concurrency flag for parallel runs.

• 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.

• The proxy architecture occasionally breaks on apps with strict CSP, service workers or unusual auth flows.
• Smaller community and slower ecosystem growth than Playwright or Cypress.
• No component testing story.

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

Small teams who want a working cross-browser suite with the least possible setup.
