## What it is
Isotope is a JavaScript layout library for creating filterable and sortable grid layouts with animated transitions, supporting multiple layout modes like masonry, fitRows, and packery. It works with jQuery, vanilla JavaScript, or declarative HTML attributes.

## Use cases
- filter and sort a portfolio grid with animations
- create a masonry-style image gallery with category filtering
- build a sortable product grid for a website
- animate reordering of card layouts in the browser
- implement a filterable list of items without a framework

## When to choose
- you need animated filtering and sorting of grid items in the browser
- you want multiple layout modes (masonry, fitRows, packery) in one library
- your project is open source under GPLv3 or you have a commercial license

## When to avoid
- your project is commercial and you cannot accept GPLv3 or purchase a license
- you need a fully MIT-licensed solution (consider Masonry instead)
- you need a maintained library - development ended around 2020 and releases are infrequent
- you are using a modern framework like React or Vue where CSS grid or framework-native solutions may fit better
