## What it is
Chameleon (CML) is a cross-platform development framework by DiDi that lets you write one Vue-like codebase and compile it to web, WeChat/Alipay/Baidu/QQ/ByteDance mini-programs, and native Android/iOS apps via Weex. It provides a polymorphic protocol so developers can still handle platform-specific differences when needed.

## Use cases
- build a mini-program and web app from one codebase
- compile a single Vue-like codebase to WeChat, Alipay, and Baidu mini-programs
- develop native Android and iOS apps without writing platform-specific code
- share UI components across web and mini-program targets
- migrate an existing web app to mini-programs

## When to choose
- you need to target multiple mini-program platforms plus web and native from one codebase
- your team prefers a Vue-like syntax and wants high consistency across platforms
- you want a mature compile-time solution with a polymorphic protocol for platform differences

## When to avoid
- you only target a single platform like web or one mini-program
- you need cutting-edge framework features or active community development - the project has seen limited updates since 2023
- you prefer mainstream ecosystems like Taro or uni-app with larger communities
