Maestro
otherOpen source end to end UI testing framework for mobile and web apps. Write your first test in under 5 minutes.
Key features
Free tier available
Mobile development teams who need reliable UI testing across iOS and Android without learning separate testing frameworks for each platform
Extremely simple YAML syntax makes test creation accessible to anyone on the team, not just developers with testing framework experience
What it does
Simple YAML Test Syntax
Write tests in plain YAML that reads like English. No complex setup, no flaky selectors. Tests are concise, readable, and maintainable even as your app evolves.
Maestro Studio (Desktop IDE)
A free all in one testing IDE with a visual element inspector, action recording, and MaestroGPT AI assistant. Find elements visually, record interactions to generate test commands, and get AI help writing tests.
Cross Platform Support
A single test framework for iOS, Android, and web apps regardless of the underlying framework: React Native, Flutter, SwiftUI, Jetpack Compose, NativeScript, .NET MAUI, Capacitor, Cordova, and more.
MaestroGPT (AI Assistant)
An AI assistant trained specifically on the Maestro framework. Generates test commands from natural language descriptions and answers Maestro related questions directly in the Studio IDE.
Visual Element Inspector
See exactly what Maestro sees on screen. Instantly find the correct element selector without guessing, making test creation fast and reliable.
Action Recording
Interact with your app in Maestro Studio and it automatically generates the corresponding Maestro test commands. Ideal for non technical team members creating tests.
Maestro Cloud
Enterprise grade cloud infrastructure for running tests in parallel at scale. Integrates into CI/CD pipelines for pre release, nightly, and pull request testing with notifications and analytics dashboards.
CI/CD Integration
Run Maestro tests on every pull request, nightly build, or release candidate. Get notifications on test results and block merges when critical tests fail.
Analytics Dashboard
Track flow runs, failure rates, average run times, and passing percentages over time. Identify flaky tests and measure quality trends across your team.

Pros & Cons
Pros
- Extremely simple YAML syntax makes test creation accessible to anyone on the team, not just developers with testing framework experience
- True cross platform coverage: one framework tests iOS, Android, and web apps regardless of the underlying technology stack
- Free and open source CLI plus a free desktop IDE means zero cost to get started and evaluate the tool thoroughly
- Used by top tier companies (Microsoft, Meta, Uber, Amazon, Stripe, Disney) which validates reliability at scale
- Maestro Studio's visual inspector and action recording dramatically reduce the time to create new tests
- Built for the AI era where development speed has increased and quality assurance becomes the bottleneck
Cons
- Cloud pricing starts at $250/device/month for mobile and $125/browser/month for web, which can add up quickly for teams needing many concurrent devices
- The YAML syntax, while simple, may feel limiting for teams that need complex test logic or custom assertions beyond what the framework provides
- Maestro Studio's web testing support is still in beta, so web app testing may have rough edges compared to the mature iOS and Android support
- Smaller ecosystem and community compared to established tools like Appium, which has years of plugins, integrations, and documentation
How to get started
Install Maestro Studio or CLI
Download Maestro Studio for your platform (Mac, Windows, or Linux) for the full visual experience. Alternatively, install the CLI for command line usage.
Write your first test
Create a YAML file describing a simple user flow in your app. Maestro tests read like plain English: launch the app, tap a button, enter text, verify a result. The documentation includes starter examples for every supported platform.
Run and iterate
Execute your test from Maestro Studio or the CLI. Use the visual inspector to find elements, the recorder to capture interactions, and MaestroGPT to help write commands when you get stuck.
Scale with Maestro Cloud
When you need to run tests in CI/CD or across multiple devices in parallel, set up Maestro Cloud. It integrates with your existing pipelines and provides analytics on test health over time.
