Flat UI vs Xamarin: What are the differences?

Developers describe Flat UI as "Free Bootstrap Framework and Theme". Flat UI is a beautiful theme for Bootstrap. We have redesigned many of its components to look flat in every pixel. On the other hand, Xamarin is detailed as "Create iOS, Android and Mac apps in C#". Xamarin鈥檚 Mono-based products enable .NET developers to use their existing code, libraries and tools (including Visual Studio*), as well as skills in .NET and the C# programming language, to create mobile applications for the industry鈥檚 most widely-used mobile devices, including Android-based smartphones and tablets, iPhone, iPad and iPod Touch.

Flat UI belongs to "Front-End Frameworks" category of the tech stack, while Xamarin can be primarily classified under "Cross-Platform Mobile Development".

Some of the features offered by Flat UI are:

  • Bootstrap-based
  • Retina Ready Images and Icons
  • Custom form components

On the other hand, Xamarin provides the following key features:

  • Cross-platform development- Thinking about supporting iOS, Android, Mac and Windows? Xamarin allows you to write it all in C#.
  • Reuse existing code- Use your favorite .NET libraries in Xamarin apps. Easily use third-party native libraries and frameworks.
  • Discover as you type- Explore APIs as you type with code autocompletion.

Flat UI is an open source tool with 14.5K GitHub stars and 2.45K GitHub forks. Here's a link to Flat UI's open source repository on GitHub.

Rdio, Olo, and Rumble are some of the popular companies that use Xamarin, whereas Flat UI is used by Apexure, Leonis Holding, and SkyQuest. Xamarin has a broader approval, being mentioned in 74 company stacks & 65 developers stacks; compared to Flat UI, which is listed in 4 company stacks and 3 developer stacks.

    Finding the most effective dev stack for a solo developer. Over the past year, I've been looking at many tech stacks that would be 'best' for me, as a solo, indie, developer to deliver a desktop app (Windows & Mac) plus mobile - iOS mainly. Initially, Xamarin started to stand-out. Using .NET Core as the run-time, Xamarin as the native API provider and Xamarin Forms for the UI seemed to solve all issues. But, the cracks soon started to appear. Xamarin Forms is mobile only; the Windows incarnation is different. There is no Mac UI solution (you have to code it natively in Mac OS Storyboard. I was also worried how Xamarin Forms , if I was to use it, was going to cope, in future, with Apple's new SwiftUI and Google's new Fuchsia.

    This plethora of techs for the UI-layer made me reach for the safer waters of using Web-techs for the UI. Lovely! Consistency everywhere (well, mostly). But that consistency evaporates when platform issues are addressed. There are so many web frameworks!

    But, I made a simple decision. It's just me...I am clever, but there is no army of coders here. And I have big plans for a business app. How could just 1 developer go-on to deploy a decent app to Windows, iPhone, iPad & Mac OS? I remembered earlier days when I've used Microsoft's ASP.NET to scaffold - generate - loads of Code for a web-app that I needed for several charities that I worked with. What 'generators' exist that do a lot of the platform-specific rubbish, allow the necessary customisation of such platform integration and provide a decent UI?

    I've placed my colours to the Quasar Framework mast. Oh dear, that means Electron desktop apps doesn't it? Well, Ive had enough of loads of Developers saying that "the menus won't look native" or "it uses too much RAM" and so on. I've been using non-native UI-wrapped apps for ages - the date picker in Outlook on iOS is way better than the native date-picker and I'd been using it for years without getting hot under the collar about it. Developers do get so hung-up on things that busy Users hardly notice; don't you think?. As to the RAM usage issue; that's a bit true. But Users only really notice when an app uses so much RAM that the machine starts to page-out. Electron contributes towards that horizon but does not cause it. My Users will be business-users after all. Somewhat decent machines.

    Looking forward to all that lovely Vue.js around my TypeScript and all those really, really, b e a u t I f u l UI controls of Quasar Framework . Still not sure that 1 dev can deliver all that... but I'm up for trying...

    I'm working in Huge company and I'm in charge to choose the cross-platform environment to develop Mobile application for all our services. I choose Xamarin but because the error i get everytime in Visual Studio, I want to leave it and recommand another solution. In fact that's why I'm here.

    Weird, Install VS2017 with Xamarin on a new PC Create a new app GOT ERRORS.....!!!!!

    Thank you for considering this

    Xamarin enables us to develop for 3 platforms (iOS, Android and Windows Phone) with one core codebase coded in C#. Xamarin has allowed us to release an app on all three platforms and develop them simultaneously - not bad for a team of 2!
