# Maestro Cloud overview

Maestro Cloud is a hosted, enterprise-grade infrastructure designed to execute automated tests with high parallelism and reliable scaling. It allows teams to run their Flows in a stable, managed environment, eliminating the need to configure or maintain local emulators and simulators.

By offloading device management to the cloud, teams can reduce test execution time by up to 90% through asynchronous parallel runs, enabling faster shipping cycles with increased confidence.

{% hint style="info" %}
Maestro does not provide a separate "Cloud CLI." To take advantage of Maestro Cloud features, you use the `cloud` subcommand within the standard [Maestro CLI](https://app.gitbook.com/s/kq23kwiAeAnHkGJYMGDk/). This subcommand uploads your app and test flows to our cloud infrastructure and enables hosted test execution.

### Core capabilities

Maestro Cloud provides a purpose-built environment that ensures deterministic results by addressing the common causes of flakiness in mobile testing.

| Capability                 | Description                                                                                               |
| -------------------------- | --------------------------------------------------------------------------------------------------------- |
| **Device Isolation**       | Every virtual device is wiped and recreated between tests to ensure complete isolation and repeatability. |
| **Flexible Configuration** | Customize exact environments, such as Android API levels or specific iOS models.                          |
| **Global Testing**         | Test localized app behavior using the `--device-locale` parameter and fixed regional timezones.           |
| **Cross-Platform**         | Native support for Android (Views/Compose), iOS (UIKit/SwiftUI), React Native, Flutter, and Web.          |

### CI/CD and workflow integration

You can integrate Maestro into your existing development lifecycle. Maestro Cloud offers native integrations with popular CI providers to automate your testing pipeline.

| Feature                      | Description                                                                                                           |
| ---------------------------- | --------------------------------------------------------------------------------------------------------------------- |
| **Native CI Support**        | Ready-made integrations for GitHub Actions, Bitrise, Bitbucket Pipelines, and CircleCI.                               |
| **Pull Request Integration** | Specifically for GitHub and GitHub Enterprise, Maestro can block merging if test failures are detected in a PR.       |
| **Performance Optimization** | Reuse cached app binaries via the `app-binary-id` to skip re-uploading the application for every individual test run. |
