Can i add openvidu in website without installing it in my server using api?
We don’t offer OpenVidu “As A Service”. It is a software that requires you to host it somewhere. And there’s really no streaming service that doesn’t require at least some backend code, I’m afraid. I was going to suggest you give Twilio or Tokbox a try, as they are the most important programmable real time video services out there, but both of them require you to manage video sessions from your backend. Of course it is that way: if you base your code only in client technology, you’d be force to have your secret api keys in the frontend and anybody could steal your credentials.
