## What it is
Marzipano is a JavaScript 360° media viewer for the web, built on WebGL, for displaying panoramas and virtual tours. It provides a powerful API for scenes, views, hotspots, and autorotation, and ships as a standalone script or npm package.

## Use cases
- embed 360° panoramas on a website
- build a virtual tour from equirectangular or cube-face panoramas
- display large tiled panorama images with good performance
- add hotspots and autorotate to a panorama viewer
- create a custom WebGL-based 360 viewer with a JavaScript API

## When to choose
- you need a lightweight (~55KB gzipped) browser-based 360° viewer
- you want fine-grained control over scenes, views, and geometry via a JS API
- you need broad desktop and mobile browser support
- you want to export a virtual tour as a deployable web app boilerplate

## When to avoid
- you need 360° video playback rather than image panoramas
- you want a fully managed/hosted tour builder with no coding
- you need active feature development - the project is in maintenance mode with infrequent releases
