Relay server

Vyapar-like outside access without hosting the customer ERP database.

Zeyto Relay is the transport plane. It lets web and mobile clients reach the customer's local Edge through an outbound WebSocket while keeping operational data local.

Inside shop

Phone or browser connects directly to the Edge LAN URL shown by the installed server.

Outside shop

Edge opens an outbound encrypted WebSocket to relay.zeyto.app. The user connects through the relay.

No router setup

The customer does not need public IP, DDNS, or port forwarding.

No ERP data in cloud

Relay sees tenant, device, audience, connection state, and encrypted/opaque payload sizes only.

Offline behavior

If relay is down, LAN access and desktop billing continue. Mobile actions queue locally.

Commercial control

Relay tokens are issued only for active licensed devices and expire automatically.

How traffic moves

Edge outbound. Devices authenticated. Messages tenant-scoped.

The relay service now exposes authenticated WebSocket endpoints and forwards messages only between connections that share the same tenant. It is intentionally not a reporting database, not a backup store, and not a second ERP server.
