• 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.

• 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.

• 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.

• 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.

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

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