• 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.

• Self-healing genuinely reduces maintenance on UIs that change often.
• Auto-captured visual, performance and accessibility signals on every run without extra setup.
• Very little infrastructure to own — no grid, no runners.

• 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.

• Cloud-only. If your application is not reachable from mabl's infrastructure, the setup gets complicated.
• Complex conditional logic hits the ceiling of the low-code model.
• Opaque pricing and a substantial minimum commitment.
