No credit card required."Voice AI has unique infrastructure demands that traditional cloud architectures aren't built for. By leveraging Cloudflare, Layercode delivers the most performant and low-latency voice AI infrastructure that scales."Dane KnechtCTO at Cloudflare"Layercode makes it very easy to build and prototype low-latency voice features for our text-based agents built with NextJS and React."Lance JonesAI Agent DeveloperVoice AI demos are easy.Production is hard.You built a working prototype in a weekend. But when real users start talking to your agent, everything breaks...The agent lags and users talk over itTurn-taking feels roboticIt mispronounces your customer's brandCalls fail and you have no idea whyScaling means rewriting your entire infrastructureThe gap between "cool demo" and production-ready voice AI can be months of work wrangling WebSocket connections, voice activity detection tuning, global deployment, session recording, observability tooling, etc.Layercode closes that gap.Not a visual builder. Not a framework. Just infrastructure.More control than Vapi or RetellVapi and Retell's visual builders work great for simple use cases and rapid prototyping. But when your logic gets complex, you start fighting their platforms instead of building your product. Layercode gives you a webhook: Write TypeScript. Ship.Simpler than LiveKit or PipecatLiveKit and Pipecat offer open-source frameworks with complete architectural control. But most teams can't afford to spend months on WebRTC, TURN servers, and audio pipeline debugging. Layercode handles the infrastructure. You handle the intelligence.More flexible than OpenAI RealtimeOpenAI's Realtime API is impressive technology and works well for simple demos. But it's a black box: you can't swap models mid-conversation, control prompts dynamically, or use your own fine-tuned LLM. Layercode calls YOUR backend. You control everything.Add voice to your Next.js app in under 50 linesLayercode's Node.js SDK integrates with the tools you already use. Here's a complete voice agent backend using the Vercel AI SDK:ServerClientapp/api/agent/route.tsimport { createOpenAI } from "@ai-sdk/openai"; import { streamText } from "ai"; import { streamResponse } from "@layercode/node-server-sdk"; const openai = createOpenAI({ apiKey: process.env.OPENAI_API_KEY! }); export const POST = async (request: Request) => { const body = await request.json(); return streamResponse(body, async ({ stream }) => { if (body.type === "message") { const { textStream } = streamText({ model: openai("gpt-4o-mini"), system: "You are a helpful voice assistant.", messages: [{ role: "user", content: body.text }], onFinish: () => stream.end(), }); await stream.ttsTextStream(textStream); } }); };Works with the LLM libraries you already use: Vercel AI SDK OpenAI Anthropic LangChain Ollama MastraHot-swap leading voice model providers: ElevenLabs Rime Cartesia Deepgram InworldView quickstartYour backend.

When your user is in Tokyo and your servers are in Virginia, latency kills the conversation. Pauses feel unnatural. Users talk over the agent.

But building production-ready voice systems is still too hard. We're fixing that.Today, any developer can ship a working demo in an afternoon. But demos aren't products. The gap between "cool prototype" and "production system" is still months of work: WebSocket infrastructure, latency optimization, turn-taking logic, global deployment. We've built serious infrastructure before, and we know not every team should have to do that work.Doctors with AI assistants that actually hear patients. Tutors that adapt to how a student learns. Support systems that respond to how someone feels, not just what they say.That's the future we're building toward.FoundersDamien TannerCEO, Co-founderStuart BownessCBO, Co-founderAidan HornsbyCMO, Co-founderWhat we believeSolve real problemsWe solve real problems for real users, period. Customer pain points are our roadmap, and customer success is our scoreboard. Everything else is just noise.Ship to learnProduct engineers don't hide behind Jira tickets. They ship to learn. Talk to actual customers. Feel the friction points firsthand. We build quickly, measure honestly, and adapt without ceremony.Adapt constantlyThe world is changing rapidly. We want thinkers who are capable of adapting to an ever-changing environment. More chameleons, less dodos.Autonomy-firstWe find exceptional people and trust them to do exceptional work. No micromanagement. No mandatory office hours. Results matter, location doesn't.Amplify with AIAI isn't replacing your job — it's eliminating the tedious parts you dread. We don't fight these tools; we use them to achieve more with less, and build things with unprecedented speed and scale.Sweat the detailsWe care deeply about quality. Not perfection, but work we're genuinely proud of. We don't ship "meh" or celebrate "good enough." If you're someone who loses sleep over details others overlook, we're looking for you.Backed for the long-termWe're building Layercode for the long haul.
