## What it is
Maestro is an open-source end-to-end UI testing framework for Android, iOS, and web apps that uses human-readable YAML flows interpreted at runtime. It ships as a CLI, a desktop test IDE (Maestro Studio), an MCP server for AI coding agents, and an optional paid device cloud for parallel execution.

## Use cases
- write e2e tests for my android and ios apps without compiling test code
- automate ui testing for react native and flutter apps
- run mobile ui tests in ci on every pull request
- let my ai coding agent write and run mobile ui tests via mcp
- test web apps in a browser with simple yaml flows
- replace flaky appium tests with a simpler framework
- run ui tests in parallel across many devices in the cloud

## When to choose
- you want fast, low-setup blackbox e2e testing for mobile or web apps
- your team prefers declarative YAML over compiled test suites like Espresso or XCTest
- you need cross-platform coverage including React Native, Flutter, and hybrid apps
- you want AI agents to author and debug UI tests through MCP

## When to avoid
- you need deep unit or integration testing inside your app's code
- you require fine-grained native access or custom instrumentation beyond what the YAML commands support
- you need a fully free parallel device cloud (Maestro Cloud is paid)
- you rely on Windows outside WSL without checking the regular Windows install path
