Maestro
Modern, YAML-based mobile UI testing. Simple syntax, fast setup, and cross-platform support for iOS and Android.
Overview
Maestro, created by mobile.dev (now part of Robinhood) in 2022, is a modern mobile UI testing framework that uses simple YAML files to define test flows. It aims to solve the complexity and flakiness of existing mobile testing tools by providing a declarative, human-readable syntax and built-in synchronisation that waits for UI elements automatically.
Maestro has gained rapid adoption in 2024-2025 as teams seek simpler alternatives to Appium. It supports both iOS and Android, runs on simulators and real devices, and can be integrated into CI/CD pipelines with minimal configuration.
What it's used for
Maestro is perfect when:
- Simple mobile test automation needed: Write tests in YAML without coding knowledge.
- Cross-platform mobile testing: One YAML test runs on both iOS and Android.
- Fast setup is critical: Install via Homebrew, write a YAML file, run — no complex configuration.
- Flaky tests from Appium: Maestro's built-in synchronisation reduces timing issues.

NZ Context
Maestro is gaining traction in NZ mobile teams that find Appium too complex or flaky. Several NZ startups have adopted Maestro for its simplicity. For NZ QA professionals looking to add mobile testing skills, Maestro is the fastest path from zero to running tests.
Alternatives
- Appium — More mature and flexible but harder to set up and maintain.
- Detox — Better for React Native specifically.
- Espresso / XCUITest — Native frameworks for Android-only or iOS-only teams.
