Xamarin vs Flutter (2026): Xamarin Is Retired, So Here Is .NET MAUI vs Flutter

Last updated: October 2026. Written by Josh Hutcheson. This comparison is based on each framework’s official documentation and release notes, the 2025 Stack Overflow Developer Survey and developer discussions, all read in October 2026. See our review methodology.

Xamarin vs Flutter was the C# vs Dart question for cross-platform apps: Microsoft’s framework against Google’s. In 2026 the question has changed, because Xamarin is retired. Microsoft replaced it with .NET MAUI, so anyone choosing today is really comparing .NET MAUI vs Flutter. This guide explains what happened to Xamarin, then compares MAUI and Flutter on language, performance, tooling, UI, platforms, jobs and long-term support.

Version numbers, support dates and platform-stability levels come from the official sources linked in this article, read on 13 October 2026. Frameworks ship new releases every few months, so check the linked release notes before you plan around a specific version.

Xamarin

Xamarin was a framework for building iOS, Android and Windows apps in C#. It launched in 2011, and Microsoft acquired the company in 2016 and made it free and open source. It came in two parts: Xamarin Native (Xamarin.iOS and Xamarin.Android), which exposed each platform’s full SDK to C#, and Xamarin.Forms, which added a shared XAML UI layer. Our Xamarin Native vs Xamarin.Forms guide covers the difference.

Microsoft’s Xamarin support policy confirms that support ended on 1 May 2024, that Xamarin.Forms “has evolved into” .NET MAUI, and that Xamarin.Android and Xamarin.iOS now ship inside .NET as .NET for Android and .NET for iOS. Android API 34 and Xcode 15 are the last targets it will ever support.

.NET MAUI, the successor

.NET MAUI is Xamarin.Forms rebuilt for modern .NET. Microsoft calls it “the evolution of Xamarin.Forms, extended from mobile to desktop scenarios, with UI controls rebuilt from the ground up for performance and extensibility.” One project builds for Android, iOS, macOS and Windows, and the old renderer model was replaced with lighter handlers that map each cross-platform control to its native counterpart.

Flutter

Flutter is Google’s open-source UI toolkit for building apps from one Dart codebase. It first appeared in 2017 and reached 1.0 in December 2018. Unlike MAUI, it does not use the platform’s own buttons and lists. Flutter draws every pixel itself with its rendering engine, which gives the same look on every device and full control over design.

Flutter now targets far more than phones. The same project can build for iOS, Android, the web, Windows, macOS and Linux. The current release is Flutter 3.47, and since Flutter 3.27 its new Impeller renderer is the default on iOS and on Android API 29 and later, replacing the Skia renderer that older comparisons describe. Impeller is the only supported renderer on iOS.

Older versions of this page said Flutter was “limited to just iOS and Android development” and that Dart was “a failure.” Neither is true today: Flutter supports six platforms, and Dart is a mature, actively developed language, even if fewer developers know it than C#.

Xamarin vs Flutter: Technology Stack

Language is the first filter. .NET MAUI uses C#, and Flutter uses Dart.

• C# is used by 27.8% of developers in the 2025 Stack Overflow Developer Survey. If your company runs ASP.NET Core, Azure functions or Windows desktop apps, a MAUI app can share models, validation and service code with them, and your existing developers already know the tools.
• Dart is used by 5.9% of respondents, almost entirely because of Flutter. It is easy to pick up for anyone who knows Java, C#, JavaScript or TypeScript: it is typed, has null safety, and reads much like those languages. Most Flutter developers learn Dart and Flutter together.

Older articles said Xamarin “wins” here because there are more C# developers. That is still true of MAUI, but it only helps if you already have those developers. For a beginner, learning Dart is a few weeks of work and is rarely the deciding factor.

Xamarin vs Flutter: Performance

Both .NET MAUI and Flutter produce fast apps when built well, but they get there differently.

• Flutter compiles Dart ahead of time to native machine code for release builds and renders with Impeller, which precompiles its shaders to avoid the first-run animation stutter (jank) that the old Skia renderer could cause. Smooth, complex animation is one of Flutter’s strengths.
• .NET MAUI uses native controls. iOS builds are fully ahead-of-time compiled; Android builds ship intermediate language that is JIT-compiled at launch, which can make cold start slower than a fully native app. .NET MAUI 10’s focus was quality and stability, including faster default handlers for CollectionView and CarouselView on iOS.

The old advice here, that Xamarin Native was faster than Xamarin.Forms because of the extra abstraction layer, still has a modern version: MAUI’s handler architecture is lighter than Forms’ renderers, but very complex screens can still need platform-specific code. Flutter avoids that layer entirely because it never maps to native widgets. We have not run our own benchmarks; published framework benchmarks vary widely with the test app, so treat any single chart with caution.

Xamarin vs Flutter: Development Environment

.NET MAUI installs as a workload in Visual Studio on Windows, which also gives you the Android emulator and Windows target. On a Mac, Visual Studio for Mac has been retired, so the supported route is VS Code with the .NET MAUI extension. Building for iOS always needs a Mac with Xcode.

Flutter installs as an SDK and works with VS Code, Android Studio or IntelliJ through official plugins. The flutter doctor command checks your setup and tells you what is missing. iOS builds also need a Mac with Xcode, but you can build and test Android, web and desktop versions on Windows or Linux.

Older versions of this page complained about adding Flutter to the system PATH by hand. That is now handled by the VS Code extension and installers, so setup is roughly equal: an hour or two for either, most of it spent on Android Studio and Xcode downloads.

Xamarin vs Flutter: Developer Productivity

Flutter’s stateful hot reload is one of its best features. You save a file and the running app updates in about a second, keeping its current state, so you can tweak a screen without navigating back to it. .NET MAUI has .NET Hot Reload for C# changes and XAML Hot Reload for UI, which work well for layout changes, though some code changes still need a rebuild.

Older comparisons quoted a “30% faster development” figure for hot reload; we could not find a source for it and have removed it.

Productivity also depends on what your team already knows. A C# developer will usually be productive in MAUI sooner. A JavaScript or Java developer, or a beginner, will often get further faster in Flutter, because its documentation, sample apps and community answers are more plentiful.

Xamarin vs Flutter: UI Components & API

This is the biggest technical difference. .NET MAUI renders each control as the platform’s own widget: a MAUI Button is a UIButton on iOS and an Android button on Android. Your app automatically looks and behaves like other apps on each platform, and picks up platform accessibility features. The trade-off is that pixel-perfect custom designs take more work, because each platform draws the control slightly differently.

Flutter draws its own widgets. It ships two full design systems, Material (Android style) and Cupertino (iOS style), plus everything needed to build fully custom designs. Your app looks the same on every device unless you choose otherwise, which is why brand-heavy consumer apps like it. The older claim that Flutter apps cannot look native on iOS is out of date: Cupertino widgets and adaptive components let you match each platform when you want to.

For device features (camera, location, notifications), MAUI includes platform APIs in the framework, and lets you call platform code directly from C#. Flutter uses plugins from pub.dev and platform channels to call Swift or Kotlin code when no plugin exists.

Xamarin vs Flutter: Community Support

Flutter has the larger and faster-growing community: more packages on pub.dev, more tutorials and more answers to everyday problems. Google even publishes a Flutter guide for Xamarin.Forms developers that maps Forms concepts to Flutter widgets.

The .NET MAUI community is smaller but backed by Microsoft documentation, Microsoft Learn training and commercial control vendors such as Syncfusion, Telerik and DevExpress. Developers who migrated from Xamarin in 2025 and 2026 report that the hardest part was third-party NuGet packages and custom renderers that never moved to MAUI, so check dependencies before you commit. The old Xamarin forums are archived; current MAUI questions go to GitHub, Stack Overflow and Microsoft Q&A.

Xamarin vs Flutter: Popularity

Flutter is used in far more public apps. The Flutter showcase includes Google’s NotebookLM, SoFi, KQED, talabat, Zoho Tables and Toyota’s in-car infotainment work. .NET MAUI is used mostly by companies that already run on .NET, often for internal or enterprise apps that never appear in public showcases. MAUI developers describe a quieter job market in 2026 discussions, with fewer remote listings than for Flutter or React Native.

This page used to list companies “using Xamarin in production.” Those lists are years out of date, and most apps on them have since been rebuilt or migrated, so we have removed them.

.NET MAUI vs Flutter: cost

Both frameworks are free and open source, so the real costs are tools, store fees and developer time.

• IDE licensing. Flutter works in free editors (VS Code, Android Studio). For .NET MAUI, Visual Studio Community is free for individuals and for up to five users in a non-enterprise organization, but companies with more than 250 PCs or more than US$1 million in annual revenue need a paid Visual Studio license (outside open-source, classroom and academic research use). VS Code with the .NET MAUI extension is another route.
• Store fees are the same for both. Apple charges US$99 a year for its developer program, and Google Play charges a one-time US$25 registration fee.
• Hardware. Either way, shipping to iOS needs a Mac with Xcode.
• Component suites. Many MAUI business apps buy commercial control suites (grids, charts, schedulers). Flutter apps more often rely on free pub.dev packages, at the cost of checking each package’s maintenance yourself.

The biggest cost is usually people. Hiring is easier for Flutter if you are recruiting mobile developers, and easier for MAUI if you are reassigning an existing .NET team.

.NET MAUI vs Flutter vs React Native

Many readers are choosing among three frameworks, not two. Here is how React Native fits in:

If you already write React for the web, React Native is the shortest path to mobile. If you write C#, MAUI is. If you are starting from zero, Flutter and React Native both have far more learning material than MAUI.

.NET MAUI vs Flutter: which should you choose in 2026?

Is .NET MAUI worth learning? Yes, if you are, or plan to be, a .NET developer: it extends skills employers already pay for. If you are choosing a first mobile framework with no .NET background, Flutter or React Native will give you more options.

3 lessons from the Xamarin era

This page used to end with three lessons from using Xamarin and Flutter. Updated for 2026, they are:

• Framework support ends, and stores enforce it. Xamarin apps still run, but Google Play’s target API rules and Apple’s Xcode requirement mean they cannot ship updates. Check the support policy of any framework you adopt: each MAUI version is supported for about 18 months, and Flutter releases every few months.
• Code sharing is real, but UI is where it leaks. Both MAUI and Flutter share most logic. MAUI apps still need platform code for some UI, while Flutter apps share UI too but need plugins or platform channels for device features.
• App size is a trade-off, not a dealbreaker. Both MAUI and Flutter add a runtime to every app, so a minimal app is larger than its native equivalent. For most apps this does not matter; for very small utility apps, native Swift or Kotlin may be the better choice; see also Kotlin vs Java for Android.

Conclusion

Xamarin vs Flutter has a clear answer in 2026: do not start anything new in Xamarin. The real decision is .NET MAUI vs Flutter. Flutter is the stronger general choice, with more platforms, a bigger community, more jobs and more control over design. .NET MAUI is the right call for C# teams, enterprise apps that share code with .NET backends, desktop-plus-mobile tools, and Xamarin.Forms apps that need a migration path.

If you are still unsure, build the same small screen in both. A day with each will tell you more about fit than any comparison table.

Frequently asked questions

Is Xamarin still used in 2026?

Only in older apps that have not been migrated. Microsoft ended Xamarin support on 1 May 2024, and its last versions target Android API 34 and Xcode 15, below what Google Play and the App Store require for new uploads. New projects should use .NET MAUI or another framework.

Is .NET MAUI better than Flutter?

For C# and .NET teams, often yes, because they can reuse skills and code. For most other developers, Flutter is the stronger choice: it supports more platforms, has a larger community and gives more control over custom UI.

Is Flutter faster than .NET MAUI?

Flutter usually has the edge for smooth animation, because it compiles Dart to native code and draws with its own Impeller engine. MAUI apps use native controls and perform well for typical business screens, but Android cold start can be slower because of JIT compilation.

Is .NET MAUI worth learning in 2026?

Yes, if you work with C# and .NET, since it extends skills employers already use. If you are new to mobile development and have no .NET background, Flutter or React Native offer more jobs and learning resources.

Can Flutter build Windows apps like .NET MAUI?

Yes. Flutter supports Windows, macOS and Linux desktop apps, plus the web, from the same codebase. .NET MAUI supports Windows and macOS but not Linux or the web.

How do I migrate a Xamarin.Forms app?

Microsoft’s supported route is .NET MAUI: convert projects to SDK-style .NET projects, replace custom renderers with handlers, swap deprecated controls such as ListView for CollectionView, and confirm every NuGet package has a .NET MAUI version. Rewriting in Flutter is an option if the UI is being redesigned anyway.

Do I need a Mac for Flutter or .NET MAUI?

Only for iOS. Both need a Mac with Xcode to build and sign iOS apps. You can build Android, Windows and (with Flutter) web and Linux apps on other machines.
