XCUITest vs Appium

Free

Free and open source

Free with Xcode, but requires macOS hardware for every CI runner — that is the real cost.

Free. The real cost is the device lab or device-cloud subscription you run it against.

Included with Xcode.

• Fastest and most reliable option on iOS, with no third-party layer to break.
• Native accessibility-hierarchy access and built-in test recording.
• Guaranteed to keep working with each iOS release.

• 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.

• iOS and macOS only, and Swift only.
• Requires macOS CI runners, which are expensive to rent or own.
• Element queries are less expressive than modern web locators.

• 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.

iOS teams that ship native and want first-party reliability.

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