Change my answersStart over

1. Mobile App Testing

Because you said: “We ship a mobile app and test it by hand”

Buyer’s guide
AppiumBest fitOpen source

The cross-platform standard for native, hybrid and mobile-web automation.

Why this fits you

  • One API and one test suite for both platforms, in the language you already use.
  • Every device cloud supports it, so you stay portable.

Main limitation

  • Notoriously slow and flaky compared to the native frameworks it wraps.
  • Setup is a genuine project: drivers, Xcode, provisioning, Android SDK, versions.
EspressoOpen source

Google's native Android UI testing framework. Fast, stable, Android-only.

Why this fits you

  • Automatic UI-thread synchronisation makes tests both fast and reliable.
  • First-party Google support, updated alongside Android itself.

Main limitation

  • Android only.
  • Testing across app boundaries requires UiAutomator alongside it.
XCUITestFree

Apple's native UI testing framework, built into Xcode.

Why this fits you

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

Main limitation

  • iOS and macOS only, and Swift only.
  • Requires macOS CI runners, which are expensive to rent or own.

2. Cross-Browser & Device Cloud

Because you said: “We ship a mobile app and test it by hand”

Buyer’s guide
BrowserStackBest fitfrom $29Paid

The largest browser and real-device cloud, with 3,500+ device/browser combinations.

Why this fits you

  • The broadest device and browser matrix available, including older versions and new devices quickly.
  • Works with essentially every automation framework, so migration is low-risk.

Main limitation

  • Parallel-session pricing gets expensive fast, and idle capacity is still billed.
  • Remote sessions are slower than local execution, lengthening feedback loops.
Sauce Labsfrom $39Paid

Enterprise-grade device cloud with deep analytics and strong security posture.

Why this fits you

  • Strong enterprise security and compliance story, including private device pools.
  • Test analytics genuinely help identify systemic flakiness rather than individual failures.

Main limitation

  • Generally the most expensive of the major device clouds.
  • Device matrix is slightly narrower than BrowserStack's.
