## What it is
A JavaScript library that automatically resizes iframes to match their content and keeps monitoring them to maintain the correct size. It supports same-origin and cross-origin iframes, ships framework wrappers for React, Vue, Angular, and jQuery, and adds an extended API for secure parent-child page integration.

## Use cases
- resize iframe to fit its content automatically
- embed a page from another domain in an iframe without scrollbars
- embed content in a WordPress site with correct iframe height
- keep an embedded widget sized correctly when its content changes
- make cross-origin iframe links and scrolling work with the parent page
- add iframe resizing to a React or Vue app

## When to choose
- you need reliable iframe height sizing that plain CSS cannot provide
- you embed cross-origin content and need communication between parent and child pages
- you want framework wrappers and a mature, long-maintained solution

## When to avoid
- your project is not GPL-compatible and you cannot purchase a commercial license (v5 cross-origin features are paid)
- you only need simple same-origin iframes you can size with CSS or a few lines of script
- you need to resize iframes in native mobile apps without a commercial license
