Appium vs. Maestro

Appium is an open-source automation framework designed for testing native, hybrid, and mobile web applications across various platforms, including iOS, Android, Windows, and macOS. It enables developers and testers to write and execute automated UI tests using a single API, regardless of the platform or programming language. Appium's architecture is built on the WebDriver protocol, allowing seamless integration with existing testing tools and workflows.

Maestro is the open-source agentic UI testing framework for mobile apps. It includes Maestro MCP, Maestro Studio, and Maestro Cloud. Maestro MCP gives coding agents a live device. Add the Maestro MCP server to Claude Code, Cursor, Codex, GitHub Copilot, Gemini CLI, or any MCP client. Teams use it in two ways. Check work while building: while the agent builds or changes a feature, it inspects the screen, taps through the new screens on an emulator, simulator, or physical Android device, and checks its own work.
