## What it is
Muuri is a JavaScript layout engine for building responsive, sortable, filterable, and draggable grid layouts with animations. It combines the capabilities of Packery, Masonry, Isotope, and Sortable into a single low-level API.

## Use cases
- build draggable kanban boards
- create masonry-style responsive grid layouts
- add drag-and-drop sorting to grid items
- filter and sort grid items with animations
- implement bin-packing layouts in JavaScript
- drag items between multiple grids

## When to choose
- you need custom grid layouts beyond what CSS can do
- you want drag-and-drop, filtering, sorting, and animation in one library
- you need nested grids or cross-grid dragging
- you want layout calculations in web workers for performance

## When to avoid
- simple CSS grid or flexbox layouts suffice
- you need a maintained framework with frequent updates
- you only need basic list sorting without grid layout
- you need React/Vue-specific integration out of the box

## Facets
- artifact type: library
- maturity: maintenance

- domain: frontend, web-development, web-design
