Things people build with this

USE CASE 1

Build a mobile app once and deploy it to Android, iOS, and web without rewriting the UI for each platform.

USE CASE 2

Share business logic and UI code across teams building for different devices.

USE CASE 3

Rapidly prototype and iterate on mobile app designs without maintaining separate native codebases.

In plain English

Weex is a framework for building mobile applications that run on Android, iOS, and the web from a single shared codebase. The idea is that a developer writes the UI once and Weex renders it natively on each platform, rather than showing a web view inside the app. The readme is minimal. It notes support for Android 4.1 and above, iOS 9.0 and above, and WebKit 534.30 and above. It links to a separate document for build instructions and points to the Apache 2.0 license. The project was originally developed by Alibaba and incubated under the Apache Software Foundation. The repository itself contains primarily the C++ core and Android SDK, with iOS and web packages linked externally.
