Declarative YAML — no imperative test code, just steps

Automatic waiting — no manual sleep() or flaky waits

Built-in retry — reduces test flakiness

Fast execution — runs quickly without setup overhead

Maestro Studio — interactive test builder (maestro studio)

Sub-flows — reusable YAML sequences for DRY tests

JavaScript scripting — GraalJS runtime for HTTP calls and data manipulation

Maestro Cloud — real device testing in CI without local simulators
