Real-Time Signaling
The signaling layer beneath modern realtime applications
Before media flows, something has to negotiate it. Sonoma operates the signaling fabric that sets up sessions, tracks presence, and delivers events at the latency realtime work demands.
Signaling is the quiet part of realtime that everything else depends on. It decides who is reachable, how a session is established, and which events reach which participants. When it is slow, the whole application feels slow. When it is wrong, nothing connects.
We run a signaling plane built for low latency and high fan-out: consistent presence, ordered event delivery, and session negotiation that holds up as concurrency climbs. It is the layer you should not have to think about, which is exactly why we think about it carefully.
What you get
A signaling plane that holds under concurrency
Session negotiation
SDP exchange, ICE coordination, and the offer and answer choreography handled reliably so media has a clean path to follow.
Presence and state
Consistent presence and connection state across regions, so your application always knows who is reachable right now.
Event delivery
Ordered, low-latency event fan-out with backpressure handling, so a surge of activity does not become a backlog.
Scales with you
Horizontal capacity that grows with concurrency, tested at the fan-out where naive designs quietly fall over.
Resilient transport
Reconnection, resumption, and graceful handling of the flaky networks your users actually live on.
Inspectable
Tracing across the signaling path so your engineers can reason about a session, not guess at it.
