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.

With Talker SDK

10 lines of code

Initialize, join channel, push to talk. That's it.

One SDK, all platforms

Identical API across iOS, Android, Web, and React Native.

We handle infrastructure

Global edge network, auto-scaling, 99.9% uptime. Sleep well.

Sub-200ms, always

Opus codec, adaptive bitrate, noise suppression built-in.

Ship in minutes, not months

Same simple API across all platforms. Copy, paste, push to talk.

17 console.log('Received from:', audio.sender);
18});
