Architecture

Web control plane, independent relay, private connector

Long-lived tunnels stay outside Vercel execution while the web application and relay share PostgreSQL authorization state.

Gatehouse Relay
multiplexed WebSocket

Gatehouse Connector

Internal Service

Next.js on Vercel provides accounts, organizations, policy, operations, and public documentation.

Supabase PostgreSQL is the durable source of truth. Redis supports ephemeral relay presence and future multi-instance routing.

The connector runs near the service and opens only an outbound encrypted WebSocket.
