Maestro

Maestro provides an end‑to‑end UI testing framework that works across iOS, Android, and web applications. Users can write, run, and debug tests through a command‑line interface or the Maestro Studio desktop application, which offers visual test creation, an element inspector, and autocomplete for device‑specific commands. The platform supports a wide range of development frameworks, including React Native, Flutter, Jetpack Compose, SwiftUI, and others, allowing a single test suite to cover multiple app types.

The tool is open source and available for free in its core tier, with optional scaling to Maestro Cloud for larger test workloads. Integration points include continuous‑integration pipelines, notifications, and result viewing, enabling teams to catch UI regressions early in the development cycle. An AI assistant, MaestroGPT, is bundled to help generate commands and answer usage questions.

Maestro is intended for developers and QA engineers who need a unified testing solution for mobile and web interfaces, as well as non‑technical contributors who can rely on visual recording and AI assistance to create maintainable UI tests.
