## What it is
qiankun is a production-ready micro frontend framework for the web, built on top of single-spa. It lets a main application load, mount, and orchestrate multiple independently developed and deployed sub-applications (potentially built with different JavaScript frameworks) with features like JS sandboxing, style isolation, and preloading.

## Use cases
- combine multiple React, Vue, and Angular apps into one web application
- split a large frontend monolith into independently deployable micro apps
- sandbox JavaScript execution of sub-applications in the browser
- isolate CSS styles between a main app and its micro apps
- incrementally migrate a legacy frontend to a new framework
- let multiple teams deploy frontend features independently
- load sub-applications on demand based on URL routing rules

## When to choose
- you need to integrate sub-apps built with different JavaScript frameworks into one shell
- you want battle-tested, production-proven micro frontend tooling used at scale
- you need runtime JS sandboxing and style isolation out of the box
- your teams need independent development and deployment of frontend pieces
- you want an iframe-like integration model without iframe limitations

## When to avoid
- you are building a small app where a single codebase is simpler
- your team has no need for independent deployments or framework diversity
- you need first-class support for modern module federation tooling like Webpack Module Federation or native ES module imports
- you require IE support without extra polyfills
- you want a lightweight solution without lifecycle conventions in sub-apps
