// VERDICT
Reach for Maestro when you want to get mobile E2E coverage quickly with declarative, readable flows and minimal setup. Skip it when you need code-first control, complex logic, or gray-box access to app internals (Detox/native tools).
Best for
The simplest way to author mobile (and now web) E2E tests - declarative YAML flows with built-in waits and tolerance for UI flakiness, runnable in minutes with almost no setup.
Avoid when
You need code-level control, complex custom logic, or deep integration with an app's internals.

// BEST FOR
- Authoring mobile E2E flows in simple declarative YAML
- Getting a first working flow running in minutes
- Built-in waits that absorb common mobile flakiness
- Readable tests stakeholders can follow
- Covering both iOS and Android (and web) from one tool
- Lowering the barrier for manual testers to automate
// AVOID WHEN
- You need code-first control and complex custom logic
- You want gray-box access to app internals (Detox)
- Deep, framework-level customisation is required
- Your scenarios exceed what declarative YAML expresses cleanly
- You need the largest mature device-cloud ecosystem (Appium)
- The target is a mobile website best tested with a browser tool

maestro test flow.yaml # a YAML flow: launchApp, tapOn, assertVisible ...// ALTERNATIVES TO CONSIDER
// FEATURES
- Declarative YAML test flows
- iOS and Android (native, hybrid, React Native, Flutter)
- Built-in tolerance for flaky UI
- Maestro Studio for visual flow authoring
- Maestro Cloud for parallel device-lab runs
- Hot-reload-style fast feedback loop
// PROS
- Dramatically simpler authoring than Appium
- Cross-platform (iOS, Android, RN, Flutter) in one syntax
- Built-in flake mitigation
- Great for QA and product teams without deep mobile expertise
// CONS
- Cloud device farm behind paid tier
- Newer project — smaller community than Appium
- YAML-based flows can hit limits on complex logic
// EXAMPLE QA WORKFLOW
Install the Maestro CLI
Write a declarative YAML flow (launch, tap, input, assert)
Run against an emulator/simulator or device
Refine flows using Maestro Studio if helpful
Run in CI via the CLI or Maestro Cloud for real devices
Keep flows current as screens change
