• One API and one test suite for both platforms, in the language you already use.
• Every device cloud supports it, so you stay portable.
• No modification to the app under test — you test the same binary you ship.

• Dramatically faster to a first working test than Appium — minutes versus days.
• Built-in tolerance for asynchronous UI removes most flake without explicit waits.
• Readable YAML that a product manager can follow.

• Notoriously slow and flaky compared to the native frameworks it wraps.
• Setup is a genuine project: drivers, Xcode, provisioning, Android SDK, versions.
• Debugging failures across the Appium/driver/device layers takes real expertise.

• YAML limits complex conditional logic and data-driven scenarios.
• Younger project with a smaller ecosystem than Appium.
• Fewer integrations with enterprise device clouds.

Teams that must cover iOS and Android from a single suite and can absorb the setup cost.

Mobile teams that want working coverage quickly without an automation specialist.
