Maestro

Maestro is an end-to-end UI testing framework designed for mobile and web applications. It supports iOS, Android, and web platforms, including various UI frameworks such as Jetpack Compose, SwiftUI, React Native, Flutter, and .NET MAUI. Tests are defined declaratively in YAML files called Flows, which represent user journeys like login or checkout. These tests can be executed via the command line interface, a desktop application called Maestro Studio, or through Maestro Cloud for scaling and continuous integration. Maestro Studio offers a visual integrated development environment that includes an element inspector for precise selector identification, action recording to generate test commands through interaction, and AI assistance via MaestroGPT for command generation and user support. The framework interprets tests without compilation, enabling fast iteration and automatic reruns on file changes. Local test execution through CLI or Studio is free, with a cloud plan available for scaling, although specific cloud pricing details are not publicly disclosed.
