## What it is
WordPress Playground runs a full WordPress site entirely in the browser (or Node.js) using PHP compiled to WebAssembly, with no server or database setup required. It ships as an embeddable iframe/JavaScript client, a CLI, and a blueprint system for provisioning WordPress instances programmatically.

## Use cases
- try wordpress in the browser without installing anything
- test a plugin against different php and wordpress versions
- embed an interactive wordpress demo in a website
- preview pull requests with a live wordpress instance
- learn wordpress development with zero setup
- run wordpress locally in nodejs for automated testing

## When to choose
- you need instant, zero-setup WordPress for demos, learning, QA, or CI
- you want to embed a live WordPress sandbox in a web page via an iframe
- you need to run PHP/WordPress in environments without a server, like browsers or mobile apps

## When to avoid
- you need a production WordPress site with real database persistence and performance
- you require all PHP extensions or native plugins that WebAssembly PHP does not support
- you need guaranteed API stability - the embed is experimental and may change
