Hi,
WebRTC is a free, open project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs.
***There will be only API implementation work, right?***
Can you please come to have a close discussion over CHAT?
We are too experienced on that platform which you want and definitely, we can assist you with a proper guideline.
Looking forward to your inputs.
Cheers,
Arup
