Maestro is an open-source end-to-end UI testing framework that supports iOS, Android, web, and hybrid frameworks like React Native and Flutter through a single test platform.

Tests are written in human-readable YAML syntax and can be created visually through Maestro Studio without requiring programming knowledge. The platform includes built-in handling for timing issues and flakiness, supports parallel testing across multiple devices, and integrates with CI/CD pipelines for automated validation.
