Maestro is a YC-backed open-source mobile UI testing framework that uses a simple YAML-based syntax to write reliable end-to-end tests for iOS and Android.
Maestro is an open-source mobile UI testing framework, backed by Y Combinator, that takes a radically simplified approach to end-to-end mobile testing by replacing code-based test scripts with a declarative YAML syntax that describes user interactions at a high level rather than at the level of platform-specific automation APIs. Traditional mobile UI testing frameworks — Appium, Espresso, XCUITest — require teams to write code that directly manipulates UI automation APIs, handle synchronization, write explicit waits, and manage platform differences between iOS and Android, creating a high barrier to entry and generating brittle tests that break with minor UI changes. Maestro abstracts all of this into simple action declarations — tap, swipe, scroll, input text, assert visible — that the framework executes against the running application with built-in synchronization that waits for elements to be ready before interacting with them.
