I have been using Panoraven but recently it had become chargeable so I have switched over to Kuula. Love that it is able show a few 360 videos within a single iframe with the selection of the photo from the thumbnail bar at the bottom.

Kuula is equally user friendly and you can easily create a tour with multiple photo uploads, similar to that of Panoraven.
Select create tour from the menu.
Add the title and click on select images and choose from your files the 360 images to upload.
You can choose the transition type. Remember to click on post.
To get the link or code to embed on your site, click on share under my tour.
With a free plan, you can build a complete walk-through tour. However, hotspots will not be visible to anyone except yourself using the free plan.
You are able to see the photos and move between them using the thumbnail bar with the free plan.
On the free account you can upload a maximum of 25 images at one time and a total of 100 images each month.
