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
