• One tool spanning web, API, mobile and desktop, which avoids stitching four frameworks together.
• Manual testers become productive in days rather than months.
• Built-in reporting and test management reduce the number of separate purchases.

• 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.

• Record-and-playback suites become brittle at scale unless someone refactors them into keywords and objects.
• Proprietary project format makes migrating away expensive — real lock-in.
• Heavy desktop IDE; version control and code review are awkward compared to plain-text tests.

• 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.

QA teams without dedicated automation engineers that need coverage across several platforms.

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