Marzipano
What it is
Marzipano is a free 360° media viewer for the web, with a tool that turns panorama files into an exportable web application. The Marzipano Tool handles files in the browser without uploading them to a server. It accepts sphere (equirectangular) or cubeface panoramas in JPEG or TIFF format; equirectangular images need a 2:1 aspect ratio. You can set panorama names and initial views, then edit the exported JavaScript, HTML, and CSS for further customization. The viewer uses WebGL and supports modern desktop and mobile browsers and devices. It is optimized for 360° images of any size and is 55KB when gzipped. Developers can use its JavaScript API, build interfaces with standard HTML and CSS, or add Marzipano as a standalone JavaScript file or npm package. A simple tour demo includes hotspots and autorotate, and another demonstrates hotspots overlaid on content from YouTube, Google Maps, and Twitter. Exported tours can be deployed to any web hosting platform. The tool is listed as free, with no account required.
