From clone to your first call
Voice API gives you a typed product surface for agents, calls, and phone numbers so you can ship without rebuilding telephony plumbing.
Go live in minutes, not months
Self host locally, then place a call through the REST API. Inspect outcomes in the operator dashboard.
Clone and self host
Clone the repo, install dependencies, and run the app locally. Same product surface as the hosted dashboard.
Place a call and review the log
Create an outbound call with POST /api/v1/calls, then open transcripts, summaries, and outcomes when it finishes.
Bring your own stack. Keep control.
Connect Twilio with your own keys, choose models on the platform, and hook finished calls into n8n or your own webhooks.

Webhooks for finished calls
Receive structured events when calls complete so automations and operators can act immediately.
API first. Operator ready.
A Vapi and Retell style product surface you can self host. Typed routes, OpenAPI docs, and a control room UI for calls and agents.
Built for builders shipping voice products
Engineers get a predictable REST API. Operators get readable call detail without drowning in raw JSON.
Clone and host on Vercel
Clone the repo and deploy to Vercel. Post call jobs run on Workflow, recordings go to Vercel Blob through the files SDK, and the typed /api/v1 surface ships with OpenAPI at https://dashboard.voice-ai.dev/api/openapi.
Dashboard for call ops
Inspect transcripts, analysis, webhook delivery, and API keys in one place without rebuilding an admin UI.
Sign up. Add keys. Place a call.
Get from zero to a live voice agent with a clear path for developers and operators.
