Flutter: If you want more mature cross-platform UI polish and are open to Dart

Microsoft-maintained, free framework for native iOS, Android, Windows and macOS apps from one C# codebase
As of 1 September 2026, .NET MAUI is free to use. The successor to Xamarin. Softwr lists it under Mobile Development. .NET MAUI is made by Microsoft Corporation, available on Windows, macOS, iOS, Android.
Overview
.NET MAUI (Multi-platform App UI) lets developers write a single C# and XAML codebase that compiles to native UI on iOS, Android, Windows and macOS. It replaced Xamarin.Forms, which Microsoft retired in 2024, consolidating what had been a separate mobile-focused product line into the mainline .NET SDK and Visual Studio tooling. The distinguishing fact is cost and cadence rather than architecture: .NET MAUI itself is free and open source under the MIT licence, funded entirely by Microsoft as part of .NET, with no separate mobile licence fee. What buyers need to track instead is .NET's support lifecycle: even-numbered .NET releases (.NET 8, .NET 10) are Long Term Support with roughly three years of support, while odd-numbered releases get about eighteen months, and MAUI's own release train has historically lagged slightly behind the core .NET release, so a team must plan upgrade cycles around Microsoft's calendar rather than its own. Buyers are organisations already invested in C# and .NET, often with an existing Windows or Xamarin codebase, wanting to extend into mobile without adopting a new language or a second toolchain. The trade-off is platform-specific polish: MAUI's Android and iOS output has historically had more rough edges (control styling gaps, tooling bugs) than Flutter or React Native at comparable maturity, and its desktop story outside Windows is thinner than its mobile one.
The honest half
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 .NET MAUI.
Cross-shopped
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Answered, with sources
Each answer names the page it came from, so you can check it rather than take our word for it.
Yes. It ships under the MIT licence as part of the free .NET SDK, with no separate mobile licence fee from Microsoft.
It is the successor. Xamarin.Forms was retired in 2024 and Microsoft provides migration tooling from it to MAUI.
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.

Softwr does not host reviews and shows no star rating for .NET MAUI, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
