The Order of the Keystone · coming soon

Every structure hides one secret.

Auth, billing, metering, the AI spine — the eight stones every AI SaaS rebuilds from scratch. The true architects don't. They own the hardened arch, point their agent at it, and ship in under twenty minutes.

Built by the operator running a 24/7 autonomous AI fleet in production — and the academy that teaches it. The same hardened patterns, packaged for you to own.

Plate 01 · the tax

Everyone rebuilds the
foundation. Architects don't.

Finite build-cycles and token budget, spent re-pouring the same commodity plumbing every project — before you write a line of the thing that's actually yours. Move the dials. See the tax.

…re-pouring auth and billing you've written a dozen times. Keystone is bought once.

Plate 02 · the arch

Eight stones. One secret
that locks them standing.

Each stone is a production system — wired, hardened, and tested before you arrive. The keystone is the contract that makes them load-bearing. Hover the arch.

Hover or tap a stone · the green wedge is the secret

Plate 03 · the proof

Watch the architect work.

Point your Claude Code at the shipped CLAUDE.md. Branding, env, auth, billing, deploy — the deterministic path, no manual file edits. Type a command:

you@keystone — ● ready
you@keystone:~$
Guaranteed deterministic path Idempotent & resumable Gates stay green

…and this is what stands.

Not a scaffold — a real app. Auth, a metered AI feature, a usage dashboard, Stripe billing, an admin view. Yours, on your own keys, the moment the timer stops.

Plate 04 · the field

Owned. Hardened.
Agent-set-up.

Boilerplate is manual and weak on AI. App-generators invent slop you can't own. Only one is all three.

Plate 05 · the tools

A living codebase — and the
tools to evolve it.

Incumbents ship frozen code. Keystone ships Claude Code skills that operate the codebase across its life — the one thing they structurally can't match.

/keystone-setup

The deterministic path, formalized + executable: config, brand, env wiring, Vercel deploy to a live URL. Protects the < 20-min promise.

/keystone-verify

Build → lint → test → sec as one command. Keep every gate green as you extend the spine into your own product.

Plate 06 · the oath

One time. Yours forever.

No subscription to run the app you bought. The only optional recurring item is an updates renewal — new features, never a ransom on what you own.

01 / One-time

Buy it once

A single purchase. No seats, no metered runtime, no surprise invoice for shipping your own idea.

02 / Forever

Runs free, always

The app you own keeps running on your own infra and keys — independent of us, indefinitely.

03 / Optional

Updates if you want

An optional renewal pulls new features. Skip it and nothing breaks — you already hold the keystone.

Mastery beats possession. We give away the stones; the way you wield them stays yours.

Plate 07 · the answers

What the architects ask first.

Why not just prompt Claude Code to build it myself?
You can — and you'll spend the painful 40% on the parts that don't demo: usage-metering reconciliation, the auth-callback deadlock, quota 429s, webhook signatures, RLS. Keystone is that 40% already built, hardened, and proven green — so your agent spends its tokens on your product, not your plumbing.
What's the stack?
Next.js (App Router, TypeScript) on Vercel · Supabase auth + Postgres with RLS · Stripe subscriptions + usage meters · a provider-agnostic AI layer (Anthropic ↔ OpenAI) with streaming · quota at the API boundary. Standard, boring, production-grade — on purpose.
Do I bring my own API keys?
Yes. BYO provider, Supabase, and Stripe keys. The app runs entirely on your accounts — that's what "own it forever" means. setup:check tells you exactly which env vars are missing before you deploy.
Is it multi-tenant?
v1 is single-tenant by design — a thin, hardened spine you fully understand. Org/teams multitenancy is the headline Pro upgrade, deliberately deferred so v1 stays leak-proof and easy to own.
What does it cost?
A one-time purchase — you own it forever, no subscription to run your own app. Founding-cohort pricing drops first in the Discord. That's what early access is for.
When does it ship?
Soon — the spine is built; we're hardening the < 20-minute setup across fresh accounts and writing the CLAUDE.md contract. Join the order and you'll get the first build and the first say.
