Pannellum is a lightweight, free, open source panorama viewer for the web built with HTML5, CSS3, JavaScript, and WebGL. It ships as a single 21kB gzipped file that can be embedded via iframe or a JavaScript API, supporting equirectangular, cube map, partial, and multi-resolution panoramas.
Use cases
- display 360 degree equirectangular panoramas on a website
- embed a virtual tour with hotspots into a page
- show real estate property panoramas without plugins
- build a lightweight photo sphere viewer
- create multi-resolution panoramic image tours
- add a panorama viewer to a web app via JavaScript API
When to choose
- you need a plug-in free, framework-free panorama viewer
- bundle size matters and you want a single small file
- you need hotspots, tours, compass headings, or video panorama support
- you want easy iframe embedding or a CDN-hosted viewer
When to avoid
- you need a full 3D engine or game-like scene authoring
- you require server-side rendering of panoramas
- you need support for very old browsers without WebGL or CSS 3D transforms
