• Automatic synchronisation with the RN bridge eliminates most timing flake.
• Same JavaScript and Jest tooling the app team already uses.
• Fast execution because there is no external driver round trip.

• 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.

• React Native only — useless for native or Flutter apps.
• Requires building a special test binary, which complicates the pipeline.
• Grey-box coupling means an RN upgrade can break your test setup.

• 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.

React Native teams that want low-flake E2E tests in their existing toolchain.

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