• Removes the maintenance burden entirely — no flaky-test triage on your side.
• You own the Playwright code, so leaving is possible.
• Coverage arrives in weeks rather than quarters.

• 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.

• It is headcount, not software — the cost profile is completely different from a licence.
• External team needs deep product context to test meaningfully.
• Fast-moving products can outpace the feedback loop with an external author.

• 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.

Funded startups that need coverage now and have no QA hire in the plan.

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