Maestro is an AI-assisted end-to-end UI testing platform for iOS, Android, and web that lets teams create, run, and scale reliable tests fast via a CLI, Maestro Studio IDE, visual testing and recording tools, MaestroGPT guidance, and cloud-powered parallelization with CI-ready reporting.

Maestro is an open-source end-to-end UI testing platform for mobile (iOS and Android) and web applications that enables teams to ship at 'agentic velocity.' It combines a human-readable YAML test format with powerful CLI and desktop apps, easy CI integration, and an AI toolkit (MaestroGPT) that can read device screen hierarchies and write comprehensive test plans autonomously. Built for reliability and speed, Maestro tests are deterministic, repeatable, and auditable. It supports cross-platform testing with a single framework, offers visual assertion capabilities, and provides cloud-based parallel execution for scaling. The platform is extensible with no vendor lock-in, battle-tested by thousands of teams, and designed to close the agentic loop for modern AI-driven development workflows.
