The short version
- Each has a real cost: EAS Build iOS builds run on macOS workers charged at a much higher rate than Linux, so the invoice is dominated by the platform you have least ability to move off.; 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.
- They diverge on capability: EAS Build covers Hosted macOS and Linux workers, Maestro covers YAML test flows.
- Prices and features above were last checked on 31 August 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
EAS Build
- iOS builds run on macOS workers charged at a much higher rate than Linux, so the invoice is dominated by the platform you have least ability to move off.
- Lower tiers queue behind higher paying customers, which is invisible until a hotfix build waits in a queue while an incident is running.
- It is specific to React Native and Expo, so a company with a native Swift or Kotlin codebase alongside gets no benefit and needs a second build system anyway.
- Deep use of managed credentials and over the air updates makes leaving harder than swapping a continuous integration provider, because the release process itself has been built around the service.
- Build failures happen on infrastructure you cannot inspect, and reproducing an environment specific failure locally is harder than with a self hosted runner you can log into.
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.

Answered from the vendors’ own pages
EAS Build: Does it work without the Expo managed workflow?
Yes. Bare React Native projects build fine, which is a common misconception that costs teams an unnecessary evaluation.
Maestro: 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.
EAS Build: Why not just use GitHub Actions macOS runners?
You can, and it is often cheaper. You then own credential management and the Xcode version treadmill, which is the work EAS is actually selling.
Maestro: 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.
EAS Build: Can JavaScript updates skip App Store review?
Yes through EAS Update, within Apple's rules about not changing the app's purpose. Native changes still require a store submission.
Maestro: 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.
Maestro: 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.
