Building a Multi-Agent Voice Command Center: How We Deployed 8 AI Agents on Supabase Edge Functions and Vercel

OPENING: We just shipped a production voice command center handling 8 concurrent AI agents orchestrated through VAPI webhooks, Supabase Edge Functions, and a normalized 8-table Postgres schema. This article breaks down the technical architecture we used to route real-time voice interactions across Load Bearing Empire's operations—from valet trash automation to real estate workflows—without managing a single dedicated server. We'll cover webhook validation patterns, agent state management in Postgres, Vercel serverless scaling, and the exact automation scenarios that let us handle high-concurrency voice traffic at the edge.
