Supported platforms
Platforms supported by Maestro: Android, iOS, React Native, Flutter, and web applications via UI-layer automation.
Maestro operates on the principle of UI-layer automation rather than code instrumentation. Like a test driver interacting with any vehicle through its controls (steering wheel, pedals), Maestro interfaces with applications through their visual and accessibility layers, regardless of the underlying technology stack.
Mobile operating systems (core)
Maestro provides comprehensive automation support for major mobile platforms:
Android: Full support for emulators and physical devices
iOS: Full support for simulators
Both platforms pass validation at scale by enterprise teams at Microsoft, DoorDash, and others for complex automation scenarios.
Framework agnosticism
Maestro decouples test automation from framework implementation by interacting directly at the UI layer. This removes the need for framework-specific instrumentation, which is a departure from tools like Detox or Appium, which depend on complex native drivers and in-app code injection.
Supported technology stacks include:
Native: Swift, Kotlin, Java, Objective-C.
Cross-platform: React Native, Flutter.
Other hybrid frameworks.
Web automation
Status: Functional with ongoing development.
Approach: Maestro extends support to web applications, enabling cross-platform test consolidation using consistent automation syntax.
Use Case: Unified testing strategy across mobile and web surfaces.
System-level interaction
Maestro supports device-level automation beyond app boundaries:
System Interaction: Navigate to Settings, modify permissions, toggle Wi-Fi, and monitor app behavior in response to system state changes.
Real-world Scenarios: Automated testing of notification handling, permission flows, and inter-app interactions.
