Xamarin and Ionic were two of the most popular ways to build one app for iOS and Android: Xamarin with C# and .NET, Ionic with web technologies. This comparison has a different shape in 2026, because one side no longer exists in its original form. Microsoft ended support for Xamarin on 1 May 2024, and its successor is .NET MAUI. So the useful question today is: if you have C# skills or an old Xamarin app, should you go to .NET MAUI, or move to Ionic and the web stack?
Status update, October 2026
Xamarin is out of support. Per Microsoft’s Xamarin support policy, support ended on 1 May 2024 for all Xamarin SDKs, including Xamarin.Forms. Android API 34 and Xcode 15 are the last SDKs it targets, so Xamarin apps cannot adopt newer store requirements without migrating. Do not start a new project on Xamarin.
Pick .NET MAUI if your team writes C#, you are migrating a Xamarin.Forms app, or you want native controls on Android, iOS, macOS and Windows.
Pick Ionic if your team writes web code (Angular, React or Vue), you want one codebase for mobile, desktop and the web, or you are turning an existing web app into an app-store app.
| Xamarin (historical) | .NET MAUI (successor) | Ionic | |
|---|---|---|---|
| Status | Support ended 1 May 2024 | Active: .NET MAUI 10 (Nov 2025) | Active: Ionic 9 (Aug 2026) |
| Language | C# / XAML | C# / XAML | HTML, CSS, JavaScript/TypeScript |
| UI | Native controls | Native controls | Web components in a WebView |
| Platforms | Android, iOS (+ others) | Android, iOS, macOS, Windows | iOS, Android, web, desktop (as a web app) |

Xamarin let C# developers build Android and iOS apps from shared .NET code. Microsoft bought the company in 2016 and made it free and open source. Xamarin.Android and Xamarin.iOS gave full access to each platform’s APIs, and Xamarin.Forms added a shared UI layer.
Those pieces have since been folded into .NET itself. Microsoft’s support policy states that Xamarin.Android and Xamarin.iOS became .NET for Android and .NET for iOS (starting with .NET 6), and Xamarin.Forms evolved into .NET Multi-platform App UI (MAUI). Developers on r/xamarindevelopers in 2026 still describe keeping old Xamarin.Forms apps alive against new App Store and Play Store requirements; most threads end with a migration plan. If you are comparing the two Xamarin flavors, our Xamarin Native vs Xamarin Forms page covers that history.
Ionic
Ionic is an open source (MIT-licensed) UI toolkit for building mobile and desktop apps with web technologies. According to Ionic, it was founded in 2012 by Max Lynch and Ben Sperry, its open source community counts more than 5 million developers, and its customers include GE, Mastercard and H&R Block. Ionic is now an OutSystems company. (An earlier version of this article named the founding company incorrectly.)
An Ionic app is a web app whose screens use Ionic’s components, which adapt their look to iOS and Android. Capacitor, Ionic’s native runtime, wraps that web app for the app stores and gives it access to device features through plugins. Per the Ionic support policy, Ionic 9 became the active version on 19 August 2026, and Ionic 8 is in maintenance until 19 February 2027. Ionic works with Angular, React and Vue.
Xamarin vs Ionic: Performance
Xamarin, and now .NET MAUI, render real native controls and run compiled .NET code, so scrolling, animation and heavy computation behave like a native app. Ionic renders its interface in the device’s WebView. On modern phones that is smooth for forms, lists, dashboards and content apps, which is most business software. It is a poorer fit for graphics-intensive apps, games or apps that process large amounts of data on the device.
The first version of this article said Ionic apps “can’t deliver native app look and feel.” That is too strong today: Ionic’s components follow each platform’s design conventions closely, and most users will not notice the difference in a typical business app. The performance gap shows up at the edges, not in everyday screens.
Xamarin vs Ionic: Technology Stack
| Layer | .NET MAUI (and Xamarin before it) | Ionic |
|---|---|---|
| Language | C#, with XAML for UI (F# possible) | TypeScript/JavaScript, HTML, CSS |
| UI framework | MAUI controls mapped to native controls | Ionic web components + Angular, React or Vue |
| Native layer | .NET for Android / .NET for iOS | Capacitor (Cordova still supported for Angular projects) |
| Shared with the web | Little (Blazor Hybrid is an option) | Most of your code and skills |
| Package ecosystem | NuGet | npm |
The deciding factor is usually what your team already knows. A C# team reuses its language, libraries and back-end code in MAUI. A web team reuses its framework, components and design system in Ionic.
Xamarin vs Ionic: Development Environment
.NET MAUI development happens in Visual Studio on Windows or in Visual Studio Code with Microsoft’s .NET MAUI extension. Building for iOS still requires a Mac with Xcode, either locally or paired over the network.
Ionic development needs Node.js, the Ionic CLI and any editor. You can build and test most of an Ionic app in a desktop browser, which makes the edit-and-refresh loop fast. For device builds you use Android Studio and, for iOS, Xcode on a Mac, the same as every other cross-platform tool.
Xamarin vs Ionic: Developer Productivity
- Ionic is faster for web developers: browser dev tools, live reload, and the same component patterns they use on the web. A working prototype can run in the browser before anyone installs a mobile SDK.
- .NET MAUI is faster for .NET developers: strong typing, Visual Studio tooling, XAML Hot Reload, and the ability to share models and services with an ASP.NET back end.
- Migration work is the hidden cost on the .NET side. Developers who moved Xamarin apps to MAUI describe it on Reddit as harder than expected, especially for apps with many third-party controls.
Xamarin vs Ionic: UI Components
.NET MAUI provides a cross-platform set of controls (buttons, lists, navigation, layouts) that become native Android, iOS, macOS and Windows controls. Commercial component vendors fill the gaps with charts, grids and data forms. Ionic provides a large library of mobile-style web components, from tabs and modals to swipeable list items, and adapts them to iOS and Android styling automatically. Because they are web components, your existing CSS and design system apply directly.
Xamarin vs Ionic: Community Support
Xamarin’s community has largely moved to .NET MAUI, the .NET community and Microsoft Q&A. The MAUI community is active but smaller than the cross-platform giants; one 2026 thread on r/dotnetMAUI asked why the remote job market for experienced Xamarin and MAUI developers had gone quiet. Ionic’s community lives on its forum, Discord and GitHub, and it benefits from the much larger Angular, React and Vue ecosystems. Ionic users on Reddit in 2026 ask the same question every framework faces (“is Ionic still worth it?”), and the common answer is yes for web teams building business apps.
Xamarin vs Ionic: Popularity
Xamarin’s popularity is now historical: no new projects should start on it. Between its successors, .NET MAUI is the default mobile option for organizations committed to .NET, while Ionic remains a common choice for enterprise web teams and agencies. Both are smaller than React Native and Flutter, which dominate cross-platform discussion; see our Xamarin vs Flutter and React Native vs Xamarin comparisons.
3 reasons why Ionic framework became popular fast
- It uses skills web developers already have. HTML, CSS and JavaScript, with Angular, React or Vue, are known by millions of developers.
- One codebase, every surface. The same app can ship to iOS, Android and the web, which matters for internal and customer-facing business apps.
- It is free and open source. Ionic Framework has been MIT-licensed from the start, and Capacitor is open source too.
Xamarin vs .NET MAUI: what changed
Microsoft describes .NET MAUI as “the evolution of Xamarin.Forms, extended from mobile to desktop scenarios, with UI controls rebuilt from the ground up for performance and extensibility.” The main differences for a Xamarin developer:
- One project instead of several: a single MAUI project targets Android, iOS, macOS and Windows.
- Desktop is first-class: Windows and macOS are supported targets, not add-ons.
- Part of .NET: MAUI ships with each .NET release and follows its support cycle. Per Microsoft’s MAUI support policy, .NET MAUI 10 shipped on 11 November 2025 and is supported until 11 May 2027.
- New handler architecture: Xamarin.Forms custom renderers need to be rewritten as MAUI handlers, which is where most migration effort goes.
.NET MAUI vs Ionic in 2026: which should you choose?
| Your situation | Better choice | Why |
|---|---|---|
| Existing Xamarin.Forms app | .NET MAUI | Microsoft’s supported upgrade path; C# code and business logic carry over |
| C#/.NET team, new app | .NET MAUI | Reuse language, libraries and back-end models |
| Web team (Angular, React or Vue) | Ionic | Reuse components, design system and skills |
| App must also run as a website | Ionic | The same code runs in the browser |
| Windows desktop app is a must | .NET MAUI | Native Windows target |
| Graphics-heavy or performance-critical app | Neither; consider native or Flutter | Native rendering matters most here |
What each option costs
All three frameworks are free to use. .NET MAUI is open source and ships with the free .NET SDK; Visual Studio Community is free for individuals and small teams, while larger companies need a paid Visual Studio license if they use the full IDE. Ionic Framework and Capacitor are free and MIT-licensed; Ionic also sells commercial products for enterprises, such as Appflow (cloud builds and live updates) and Identity Vault (secure authentication), which most small teams never need. Whichever you choose, publishing costs the same: an Apple Developer Program membership for the App Store and a Google Play developer account for Android.
How to migrate an old Xamarin app
You have three realistic paths:
- Upgrade to .NET MAUI. Microsoft’s support page links to its official guide for upgrading Xamarin projects to .NET and .NET MAUI. This keeps your C# code and is usually the cheapest path for Xamarin.Forms apps, but budget time for custom renderers and third-party controls.
- Move Xamarin.Android / Xamarin.iOS apps to .NET for Android / .NET for iOS. Microsoft says these should be upgraded to .NET SDK-style projects for continued support.
- Rewrite in another stack. If the app is small or the team now works mainly in web technologies, a rewrite in Ionic, React Native or Flutter can cost less over time than maintaining a migrated codebase nobody on the team enjoys.
How to learn .NET MAUI or Ionic
For .NET MAUI, the best starting point is free: Microsoft’s Build mobile and desktop apps with .NET MAUI learning path on Microsoft Learn, a beginner path of 8 modules and about 6 hours 39 minutes. We have no affiliate relationship with Microsoft; it is simply the most current material.
For Ionic, these were the strongest options when we checked them on 13 October 2026:
| Course | Rating / size | Notes |
|---|---|---|
| Ionic: Build iOS, Android & Web Apps with Ionic & Angular (Udemy, Maximilian Schwarzmüller) | 4.5 from 17,188 ratings | Last updated 4/2024, so it predates Ionic 9; the Angular and Capacitor fundamentals still apply |
| Developing Mobile Apps with Ionic and React (Educative) | Text-based, interactive | For React developers who prefer reading to video |

Conclusion
Do not start anything new on Xamarin. If you write C# or are migrating a Xamarin.Forms app, move to .NET MAUI. If you are a web team or want to reuse a web app, choose Ionic with Capacitor. If neither fits, React Native and Flutter are the larger cross-platform ecosystems; our React Native vs Ionic, React Native vs Flutter and native vs hybrid apps guides compare them, and the best mobile app programming languages covers the languages behind them.

Frequently asked questions
Is Xamarin still supported?
No. Microsoft ended support for all Xamarin SDKs, including Xamarin.Forms, on 1 May 2024. Android API 34 and Xcode 15 are the last SDKs Xamarin targets. Microsoft recommends migrating Xamarin.Forms apps to .NET MAUI and Xamarin.Android or Xamarin.iOS apps to .NET for Android and .NET for iOS.
What replaced Xamarin?
.NET Multi-platform App UI (.NET MAUI) replaced Xamarin.Forms, and .NET for Android and .NET for iOS replaced Xamarin.Android and Xamarin.iOS. .NET MAUI 10 shipped in November 2025 and is supported until May 2027.
Is Ionic still worth learning in 2026?
Yes, if you are a web developer who wants to ship mobile apps. Ionic 9 became the active version in August 2026, it works with Angular, React and Vue, and it lets the same code run on iOS, Android and the web. It is less suited to graphics-heavy apps.
Is Ionic better than Xamarin?
For new projects, Ionic is the better choice of the two simply because Xamarin is out of support. The real comparison today is Ionic vs .NET MAUI: Ionic for web teams and apps that also need a website, .NET MAUI for C# teams and Xamarin migrations.
Is .NET MAUI faster than Ionic?
Generally yes for demanding apps, because .NET MAUI uses native controls and compiled .NET code while Ionic renders in a WebView. For typical business apps such as forms, lists and dashboards, Ionic performs well on modern phones.
Can I convert a Xamarin app to Ionic?
Not automatically. Ionic uses web technologies, so moving from Xamarin means rewriting the UI and most app code in HTML, CSS and TypeScript. It can make sense for small apps or teams that now work mainly on the web; otherwise upgrading to .NET MAUI keeps your C# code.
Who owns Ionic?
Ionic was founded in 2012 by Max Lynch and Ben Sperry and is now an OutSystems company. Ionic Framework itself remains free and MIT-licensed.
