• 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.

• Unmatched coverage of enterprise packaged software, especially SAP end-to-end processes.
• Model-based design means one change updates every affected test case.
• Risk-based prioritisation is a real answer to eight-hour regression packs.

• 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.

• Expensive, and priced for organisations with a procurement department.
• Steep learning curve; most customers buy consulting alongside the licence.
• Heavy and slow compared to modern code-first tools for plain web applications.

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