• 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.

• Smart locators handle everyday UI churn well.
• The escape hatch to real JavaScript keeps complex cases possible.
• Reusable shared steps keep large recorded suites maintainable.

• 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.

• Test logic lives in the vendor's cloud rather than your repository, which complicates review and branching.
• Run-based pricing punishes running the full suite on every commit.
• Post-acquisition roadmap is bound to the wider Tricentis strategy.

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

Teams with fast-changing UIs that need maintenance to stay low.
