Detox vs XCUITest

Free and open source

Free

Free and open source. You pay in engineering time and CI minutes.

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

Everything, self-hosted

• 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.

• 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.

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

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