The short version

  • Each has a real cost: .NET MAUI its release and support lifecycle is tied to the underlying .NET version, so a team on an odd-numbered .NET release faces a support cutoff roughly every eighteen months and must budget upgrade work accordingly.; 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: .NET MAUI covers Single C# and XAML codebase, Maestro covers YAML test flows.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

.NET MAUI

  • Its release and support lifecycle is tied to the underlying .NET version, so a team on an odd-numbered .NET release faces a support cutoff roughly every eighteen months and must budget upgrade work accordingly.
  • Platform-specific control styling and native look-and-feel have historically needed more manual work and workaround packages than Flutter delivers out of the box.
  • macOS and desktop support are less mature than the iOS and Android targets, so teams wanting a strong Mac app experience often still reach for native AppKit or a dedicated tool.
  • The talent pool of mobile developers fluent in MAUI specifically is smaller than for Flutter or React Native, even though C# itself is common.
  • Third-party control libraries such as Syncfusion and Telerik fill real gaps in the built-in component set, meaning a serious app often carries an additional commercial licence cost despite the framework itself being free.

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

.NET MAUI: Is .NET MAUI really free for commercial apps?

Yes. It ships under the MIT licence as part of the free .NET SDK, with no separate mobile licence fee from Microsoft.

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.

.NET MAUI: Is this the same as Xamarin?

It is the successor. Xamarin.Forms was retired in 2024 and Microsoft provides migration tooling from it to MAUI.

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.

.NET MAUI: How long is each .NET version supported?

Even-numbered releases get Long Term Support (around three years); odd-numbered releases get roughly eighteen months, and MAUI follows that same .NET release cadence.

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.
