Almost every developer working with 360 images will build a web site to share the 360 images at some point. This might only be for testing or to share with team members, but it could also be to show clients or customers.

Fortunately, there are many pre-built libraries and services to display 360 images in your custom web site.

A growing list of viewers is available here:

I’ll include a list of 12 popular viewers below. Thanks to eGene of 360 Photo to Video Online Converter for getting this list started.

Pannellum

Pannellum is a free open source panorama and 360° viewer. It’s small, fast, easy to use. Though pretty basic, it has an interesting feature — multires panoramas (ability to use images with different resolution depending on zoom for single panorama). It claims to work in all modern browsers with WebGL support. Mobile browsers are not officially supported, so they may or may not work properly.

360 Image Viewer

It’s a basic panorama viewer that doesn’t have lots of features, but it still can work for you depending on your needs as it does the job. Some settings include: field of view, rotation speed, damping and that’s pretty much all. It provides ability to set a callback function on frame change, so some customization is possible. Please note that its navigation mode is different from some other viewers: it uses what is called QTVR style when to navigate the image you need to press mouse button and move the cursor (and it can’t be changed to “drag” style). Check it out below or on their demo page to see if you are comfortable with it.
