Build native apps on iOS and Android.

Simpler. Faster.

Don't just prototype it. Build it.

Fuse empowers designers to build the layout, animations and interactions themselves. All in real time, across any screen size, allowing you to build beautiful and dynamic interfaces, easily.

Own the UI

UI, layout, animation and interaction is all built into Fuse, in a way that makes sense. Everything you create in Fuse is editable even after developers get involved, and it's easy to go back and forth.

Do more with code and real data

Go beyond traditional sketches and dummy data - design with real data and assets.

Code you can understand

UX is a declarative markup language that works in a way familiar to designers. Ideas like hierarchy and relative positioning make building the UI feel as intuitive as traditional prototyping.

Ways to Fuse

No matter what your current process is, Fuse fits in your workflow: from prototype, to app, to embeddable components.

Real app prototype

Make usable prototypes on device to share with your team and test with users.

Full production app

Build full-scale production applications across iOS and Android.

Fuse Views

Make components in Fuse and use them in Xcode and Android Studio.

Create anything

With Fuse you can build all kinds of apps and interactions. We've created a long list of examples with full source code that you can download.

Make apps in real time.

Adjust layout, UI, animation and anything else you can imagine, while the app is running. Test your changes on multiple screens simultaneously. This is how apps are supposed to be made.

App development is teamwork

It can be hard to keep designers, developers and stakeholders on the same page, but with Fuse, they can all work together. When you work in Fuse, you always work on the actual app, and things stop getting lost in translation.

Native in every way

Native performance, native UI and native APIs. Use the full potential of the devices you are targeting. Anything you can do with the native platform provider tools, you can do with Fuse, even include Objective-C, Java or Swift code.

A development tool for everyone

Fuse makes it easy for people with little or no app development experience to get started. Creating your layout, UI and animations declaratively and writing business logic in JavaScript is incredibly accessible. All without sacrificing performance.

Build better apps faster.

The combination of Fuse's powerful UX engine and live-preview means that constructing dynamic and functional apps is easier than ever. Just press "Save" and the app updates in real time. Iterating on functions or designs suddenly become fun instead of a chore.

JavaScript, but no hybrid

In Fuse, JavaScript is only used for scripting. It runs on a separate thread and doesn't interfere with your UI or animations.

The Fuse architecture

Simplicity should not come at the sacrifice of performance. Fuse compiles down to 100% native C++ to ensure that your apps perform as you intended.

Declarative UI, interaction, and animation

UX markup is a simple XML-based language that we designed to handle the front end. Build the UI in UX markup and implement logic and data in reactive JavaScript.
