Included foundations

The boring-but-critical pieces every SaaS needs before feature work

Multi-tenant model

Tenant isolation patterns and membership so orgs stay separated from day one.

Stripe billing

Plans, checkout, customer portal hooks, and webhook handling for subscriptions.

Auth ready

Sign-up, login, sessions/tokens, and role checks you can extend for SSO later.

Teams and invites

Invite flows and basic org management so customers are not stuck as solo users.

API surface

REST endpoints and a clear place to hang your domain features.

Postgres schema

Migrations and a sensible starting schema instead of a greenfield scramble.

Stack

Modern defaults you can keep or swap as you grow

Frontend

Next.js
App Router, TypeScript, Tailwind

Backend

Node API
Auth middleware, Stripe webhooks

Data

Migrations and seed scripts
