Relaycast is winding down Programmable Video on 31 March. Our WebRTC team has moved 400-odd apps off it already, and we will sit with yours until the last room is switched over.
A named solutions engineer and a customer engineer are assigned the day you start the migration, at no extra cost, until you tell us you are done.
We do not sell messaging, telephony, or a marketing suite. Every engineer here works on the real-time stack you would be buying.
Start with a prebuilt room element, then drop to the React SDK for the parts you want to own. You are never forced to rebuild the basics.
Paste an embed tag, pass a room URL, ship. Most teams have a working call in an afternoon and a production room the same week.

“Relaycast was clunky and expensive to keep alive. We were filing a call-quality ticket most weeks and hearing back the week after. Halden gave us a plain, stable platform, and their support team stays in the thread until the thing is actually fixed.”

Halden was shaped around digital healthcare: rooms that can be run under HIPAA including recording, waiting rooms that behave like waiting rooms, and audit trails your compliance lead will read. Vitalis, Careloop and Medra all run their consultations on it.
