## What it is
Zoid is a JavaScript toolkit for building cross-domain components that render as iframes or popups on a different domain while passing props, objects, and functions between parent and child windows. It abstracts away postMessage plumbing and provides native bindings for React, Vue, and Angular.

## Use cases
- render an iframe component on another domain and pass props and callbacks
- embed a login widget from my site into other sites
- open a popup and communicate with it without dealing with postMessage
- share functionality from my site as an embeddable component
- render a cross-domain component as a React or Angular component
- build data-down actions-up components across domains

## When to choose
- you need to embed interactive UI from your domain into third-party pages
- you want iframe/popup communication without hand-rolling postMessage
- you need framework bindings (React, Vue, Angular) for cross-domain widgets

## When to avoid
- your components run entirely on a single domain
- you need server-side rendering of the embedded component
- you want a general-purpose state management or micro-frontend solution

## Facets
- artifact type: library
- maturity: active
- function: ui-components, middleware, developer-tools
- domain: web-development, frontend, apis, cross-platform
- platform: browser
- tags: cross-domain, iframe, popup, postmessage, react, vue, angular, ember, web-components, nodejs, javascript
