Push-to-Talk SDK
for Modern Apps
Real-time voice communication infrastructure that works. Messaging, channels, presenceβship in days, not months.
Hold to talk β’ Release to send
Building voice is hard.
Until it isn't.
We spent years solving WebRTC pain so you don't have to.
Building in-house
Months of WebRTC debugging
NAT traversal, codec negotiation, echo cancellation β it never ends.
Different code per platform
iOS, Android, Web β three codebases to maintain, three times the bugs.
Scaling nightmares
Media servers, TURN servers, load balancing β infrastructure that breaks at 2am.
Audio quality issues
Choppy audio, high latency, background noise β users complain constantly.
