At Xamarin, we believe that great, native mobile user experiences have the power to transform customer relationships and employee productivity. Unlike other cross-platform mobile frameworks that deliver lowest common denominator experiences through UI abstraction libraries, we make 100% of the iOS and Android APIs available through our native bindings. Xamarin developers deliver high performance, fully native experiences and also share on average 75% of their source code across platforms.
Xamarin is the only platform with complete API coverage and deep code-sharing capabilities across iOS, Android and Windows apps, for a total of 2.6 billion devices you can reach in C#.
To develop cross-platform apps with Xamarin, simply create a single Xamarin Studio or Visual Studio solution with multiple projects. Developers will typically have one project per target platform, as well as shared library projects with abstracted business logic. Visual Studio's solution architecture was designed with this in mind, so if you've developed Windows applications for multiple Microsoft frameworks (such as WPF, Windows Phone, ASP.NET, Silverlight, or Windows.Forms), this approach will be familiar to you.
Yes! Unlike other cross-platform frameworks, your Xamarin app is compiled to a native binary, not interpreted. Native compilation gives users brilliant app performance for even the most demanding scenarios like high frame rate gaming and complex data visualizations. With a small footprint (2.5 MB added to your application code), and negligible impact to app startup time, you can build apps that run fast on any device.
Sound too good to be true? Watch this short video of some high-performance Xamarin apps.
On Android, Xamarin ships a fully functional implementation of the .NET runtime, called Mono, bundled with your app so that your code executes with all of the power of C# and .NET, including JIT-compilation, memory management, reflection, and the .NET base class libraries. Developers can use any native features by interacting with .NET class libraries that provide one-to-one mappings to all of the native APIs on Android.
On iOS, Xamarin uses Mono, a fully functional implementation of the .NET runtime, to fully compile your app into a native ARM executable ahead of time (AOT) so that your code executes with all of the power of C# and .NET, including memory management, reflection, and the .NET base class libraries. Developers can use any native features by interacting with .NET class libraries that provide one-to-one mappings to all of the native APIs on iOS, while complying with Apple's security restrictions which prevent execution of dynamically generated code on device.
Exactly! Xamarin's native bindings provide a complete one-to-one mapping of 100% of the native APIs on each target platform, ensuring that developers have the full power of the underlying platform at their fingertips. Anything that can be done in Objective-C and Java can be done with Xamarin.
Yes! Xamarin ships native binding project templates that make it easy to consume Objective-C and Java libraries on iOS and Android respectively, and many .NET library vendors (including Microsoft) are shipping Xamarin-compatible libraries today. The Xamarin Component Store has a growing portfolio of popular libraries ready for you to integrate into your apps with just a few lines of code.
You can write 100% of your app in C#. UI, business logic. Everything.
Yes! Xamarin ships native binding project templates that make it easy to consume Objective-C and Java libraries on iOS and Android respectively. Xamarin also has full support for building hybrid applications if you're moving from a mobile web application or other hybrid mobile app solution.
Yes! C# code that is not platform-specific (e.g., code that does not call Windows-specific functionality directly) can be easily ported to iOS and Android with little to no code changes.
Xamarin is for all mobile developers who want to reach users on major device platforms with great, native apps. Increasingly, app publishers and companies who initially built apps in Objective-C and Java are standardizing on Xamarin to share code across platforms, to go faster, and to spend more time on features and user experience, and less time maintaining disparate, duplicate code bases. Popular music streaming service, Rdio, is a great example of this.
The transition to C# is easy, and the language offers many advantages for mobile development.
Yes! Xamarin has full support for building hybrid applications. We recommend restricting HTML use to non-interactive web views and using native functionality for the interactive parts of your application.
Yes! Through code re-use and sharing, and by unifying mobile app development in C#, Xamarin makes it possible to deliver gorgeous, performant, native apps for all major device platforms quickly. Because Windows Phone and Windows 8 apps can be built in C#, Xamarin developers are already empowered to share code between iOS, Android, Windows Phone and Windows 8 apps for 2.6 billion devices.
Xamarin requires the platform SDKs from Apple and Google to target iOS or Android, and our system requirements match theirs. To build for iOS, you'll need the latest iOS SDK (currently iOS 6), which requires an Intel-based Mac running OS X 10.8 (Mountain Lion). Our Visual Studio Extensions for iOS and Android support any non-Express editions of Visual Studio 2010 and Visual Studio 2012.
After less than two years in business, Xamarin is used by 230,000 developers to build consumer, gaming, and enterprise apps, and has more than 12,000 paying customers including Clear Channel, Rdio, Portland Trailblazers, National Instruments, and McKesson. Growing extrememly fast, we are adding an additional 18,000 users to our developer community every month.
With offices in San Francisco and Boston, we have 62 employees in 14 countries. Financially, the company bootstrapped it's first year, funding operations from revenue. In July, 2012 we raised a $12M Series A round from three top tier venture capitalists to accelerate the growth of our developer community and expand our product portfolio.
When you begin a Xamarin Trial, you get access to the full Xamarin Business feature set, including the ability to run your app on actual device hardware, for 30 days. Apps built in trial mode can only be run within a 24 hour window after they are built, and bear a splash screen that indicates they were built using the Trial SDK. The Xamarin Trial is licensed for evaluation purposes only.
Xamarin Starter allows developers to build and publish simple apps, which contain no more than 32k of compiled user code (IL), and which do not call out to native third party libraries (i.e., developers may not P/Invoke into C/C++/Objective-C/Java. See the full product comparison chart.
Xamarin Business includes all the features of Xamarin Indie, as well as email support and business features, including support for WCF and System.Data.SqlClient. Additionally, Xamarin Business supports developing, deploying, and debugging apps from within Visual Studio. See the full product comparison chart. Xamarin Business may be used by companies of any size.
