Yes, it’s possible. We built a video conferencing app using Tokbox, which is built on WebRTC. Then we iframe the video into our Bubble app. Apple just recently started supporting the WebRTC standard (which enables streaming via the browser without downloads) so it’s now available on Safari 12 in Beta. Already worked on Chrome, Firefox, etc. This is the same technology that Google Hangouts is built on, for context. We use Tokbox because they take care of all of the complicated aspects of video calls. Still required a custom build on top of Tokbox’s APIs though.
There’s aren’t currently any cheap solutions for this though – that’s the one drawback. At least, we weren’t able to find any cheap solutions before we built our system a year ago.
