Vercel, Supabase, and Resend as a Hermes Control Plane

Map a production-friendly control plane where Vercel receives requests, Supabase stores state, Resend sends mail, and a local relay handles private machine work.

What the local Hermes build teaches

This build lab focuses on the web control plane around a local or hybrid Hermes-style agent. The goal is not to copy a private machine setup. The goal is to learn the architecture pattern well enough to build a small, classroom-safe version.

A web control plane should handle UI, auth, webhooks, job queues, audit logs, and notifications while private desktop actions remain behind a local relay.

Hermes pattern	Student build	Risk to handle
Name the boundary	an architecture diagram with Vercel, Supabase, Resend, local relay, and agent workers	putting service-role keys in the browser or expecting a serverless function to act like a permanent desktop controller
Keep the interface small	Start with one happy path and one failure path	Avoid a demo that only works when everything is perfect
Make the system observable	Log decisions, status, and errors in plain language	Do not log private data or secrets

Build the small version

Draw or write an architecture diagram with Vercel, Supabase, Resend, local relay, and agent workers.
Mark which parts are user-facing, which parts are internal, and which parts require approval.
Choose one low-risk workflow and implement only that workflow first.
Add one failure case before adding a second feature.
Write a short operator note: what the agent may do, what it must ask about, and what it must never do.

control plane flow:
  browser -> Vercel API
  Vercel API -> Supabase job_queue
  local relay -> polls authorized jobs
  relay -> executes approved local task
  relay -> writes audit result
  Vercel cron -> sends summary via ResendA classroom-safe skeleton inspired by the local Hermes architecture scan.

The big idea: control plane is not decoration. It is part of the product architecture students need before an agent becomes safe enough to use with real people.
