Maestro
Mobile UI testing in a few lines of YAML, with tolerance for flakiness built in.
What it is
Maestro describes flows as short YAML files and handles waiting, retries and asynchronous UI settling internally, which removes the majority of hand-written synchronisation code. It works with native iOS and Android, React Native and Flutter, requires no app modification, and starts running in minutes rather than days.
Best for
Where it is strong
- Dramatically faster to a first working test than Appium — minutes versus days.
- Built-in tolerance for asynchronous UI removes most flake without explicit waits.
- Readable YAML that a product manager can follow.
Where it falls short
- YAML limits complex conditional logic and data-driven scenarios.
- Younger project with a smaller ecosystem than Appium.
- Fewer integrations with enterprise device clouds.
