Maestro vs. TestGrid

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.

TestGrid is the AI operating system that runs quality engineering. It pairs agentic test creation and maintenance with the infrastructure those tests execute on, including real mobile devices and browsers across dedicated cloud, on-premises, and hybrid deployments. CoTester, TestGrid's AI testing agent, turns requirements and user stories into executable tests and uses self-healing capabilities to help keep automation stable as application interfaces change. Existing Selenium, Appium, Cypress, and Playwright suites run on TestGrid without rewrites.
