Hosted Web Apps

Build great Windows 10 apps with your existing website code whether you’re using a Windows PC or a Mac. Choose your development platform, then follow the instructions.

What are Hosted Web Apps on Windows 10?

For existing web applications, Windows 10 makes it easy for you to create a Universal Windows Platform (UWP) app that packages your website for publishing to the Store.

  • Look great across all Windows-based devices, including PCs, tablets, phones, HoloLens, Surface Hub, Xbox and Raspberry Pi.
  • Update and call native Windows APIs from JavaScript running on your website, creating a more engaging user experience.
  • Integrate with Cortana voice commands.
  • Debug your app with Microsoft Edge F12 Developer Tools.
  • Track status, ratings, and reviews, see analytics, and get paid for all of your Windows app in the Windows Store.

Start your app

Create your app with Visual Studio on Windows

With Visual Studio, you can create your very own Hosted Web App in a matter of minutes. The free, full-featured Visual Studio Community 2015 includes the Windows 10 developer tools, universal app templates, a code editor, a powerful debugger, Windows Mobile emulators, rich language support, and much more.

Create your app with ManifoldJS or App Studio on a Mac

If you do not have access to Visual Studio, there are a few options from which you can choose. ManifoldJS is a Node.js app that easily installs from NPM. You can also use App Studio, a free, online app creation tool that allows you to quickly build Windows 10 apps.

Convert your Chrome app to work on the Universal Windows Platform

We have made it easy to convert your existing Chrome hosted app to a Windows Hosted Web App with the HWA-CLI tool, which generates an .appx package from your existing .zip or .crx files.
