Appium vs Detox
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Strengths
- 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.
- 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.
Limitations
- 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 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.
Best for
Teams that must cover iOS and Android from a single suite and can absorb the setup cost.
React Native teams that want low-flake E2E tests in their existing toolchain.
