Maestro
Open source mobile UI testing with YAML flows, and a cloud priced per concurrent device rather than per test minute
As of 30 August 2026, Maestro has a free plan and paid plans start at $250/month. A mobile and web UI test runner where tests are YAML files rather than code, from the team formerly known as mobile. Softwr lists it under Mobile Development. Maestro is available on iOS, Android, Web, macOS.
Overview
What Maestro does
Maestro runs end-to-end UI tests against iOS, Android and web applications. Tests are written as YAML flows listing actions such as tapping, typing and asserting visible text, with waiting and retry behaviour built into the runner rather than added by the test author. That design targets the single largest cost in mobile UI testing, which is not writing tests but maintaining flaky ones. Maestro Studio provides an interactive authoring surface, and the toolchain includes a viewer, an MCP integration and self-healing behaviour driven by local agents. The CLI is free and open source and runs against simulators, emulators and physical devices you already own. The cloud product is where the commercial decision sits, and its unit is unusual. Maestro Cloud is 250 USD per device per month and includes unlimited hosted test runs. The metered resource is maximum concurrent executions, not minutes, runs or test count. That inverts the usual device farm calculation: a team that runs an enormous suite overnight on two devices pays 500 USD a month regardless of volume, while a team that needs the suite green in eight minutes on every pull request buys concurrency and the number multiplies quickly. Working out the concurrency required to hit a target suite duration is the arithmetic to do before signing, and it is a different question from the per-minute billing of most competitors. Buyers are mobile teams that have abandoned or never adopted Appium and want tests that survive a UI refactor, plus continuous integration that does not require maintaining a device lab. The trade-offs are expressiveness and depth: YAML covers common flows well but complex conditional logic pushes you into embedded scripting, and because Maestro drives the app as a black box it cannot reach into application state the way an in-process framework can.
What people use it for
- A mobile team replacing an Appium suite that spends more engineering time on maintenance than on new coverage
- Running smoke tests on every pull request without buying and maintaining a physical device lab
- Letting a QA specialist who does not write application code author and own the end-to-end suite
- Reproducing a reported bug by recording the exact flow in Studio and committing it as a regression test

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Maestro.
- Cloud pricing is per concurrent device at 250 USD per month, so the cost is driven by how quickly you need the suite to finish rather than by how much you test, and a team wanting a fast pull request gate buys several devices at once.
- YAML is deliberately limited, so tests with real conditional logic or data-driven permutations end up in embedded scripting blocks where the readability advantage that justified the format disappears.
- Maestro drives the app as a black box, so it cannot assert on internal state, mock a network layer from inside the process or inspect application memory the way an in-process framework can.
- The hosted device catalogue is narrower than dedicated device clouds, so testing against a long tail of specific manufacturer builds and older operating system versions still requires another provider.
- The project rebranded from mobile.dev to Maestro, so a share of existing tutorials, blog posts and links point at old domains and documentation that no longer match the current tooling.

Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
Is Maestro free?
The CLI, Studio and local execution are free and open source. The hosted device cloud is 250 USD per device per month.
What exactly does per device mean?
It is a concurrency slot. One device runs one test at a time, so suite duration is a function of how many devices you buy.
How does it compare with Appium?
Tests are YAML rather than code and flakiness handling is built in, which reduces maintenance, at the cost of lower-level control.
Can it test web applications too?
Yes, the cloud offers hosted web devices alongside Android and iOS, though the product centre of gravity is mobile.
