01 / The launch core
Scroll through the production layers that usually consume the first months of a build.
Email, Google OAuth, sessions, recovery, verification, and account security already share one model.
Membership, invitations, roles, and tenant boundaries are connected before your first customer arrives.
Checkout, webhooks, entitlements, invoices, and customer state move together instead of drifting apart.
Users, access, products, releases, waitlists, and support controls live in one protected workspace.
Typed schemas, migrations, health checks, and production-safe data paths give the product a durable core.
S3-compatible uploads, versioned downloads, transactional email, and notifications complete the loop.

02 / Inside the kit
57 working features across 9 connected systems. Every count comes from the actual product catalog.
better-auth with verified email, Google sign-in, and the account screens users expect.
Multi-tenant workspaces with invitations, roles, and per-org settings — the part that takes a month.
Stripe subscriptions and one-time purchases, including the webhook edge cases nobody warns you about.
A versioned REST API with per-user keys, and signed outbound webhooks with a delivery log.
Direct-to-S3 uploads, one notification dispatcher, and transactional email that already renders.
The public site: MDX content, real SEO, waitlist mode, and consent-gated analytics.
The internal tool you would otherwise build twice: users, money, files, and an audit trail.
Flags, an AI module, rate limiting, security headers, and error tracking — all optional, none crashing when off.
One command to a running stack, tests that already pass, CI, and a doc per feature.
03 / Flight plan
Create your account, purchase lifetime access, and download the complete source immediately.
The setup flow provisions local services, runs migrations, and leaves you with a working account.
Keep, reshape, or remove anything. Every system is documented for exactly that kind of ownership.
In production
Real products, live on their own domains, running on the same foundation you would be downloading.
04 / One pass, every kit
The pass grows. Your price does not. Everything released now and later lands in the same downloads account.
