One codebase, two apps

Web and mobile share API, validation, permissions and formatting. You write the rules once.

apps/web

Next.js with Cache Components, Server Actions and a tRPC endpoint.

apps/mobile

Expo and React Native with Expo Router, Uniwind and an offline queue.

packages/*

Shared code: database, DAL, auth, API, validation, formatting.

@repo/apitRPC router

@repo/authSessions and can()

@repo/dalData access

@repo/dbDrizzle schema

@repo/validationZod schemas

@repo/formatDates and numbers

@repo/domainDomain logic

Same tRPC API

Same can() check

Offline queue with replay

Organization switching

Everything every SaaS builds twice

Wired up once, properly, so you work on the product instead of the plumbing.

Sign-in with two-factor

Email and password via better-auth, reset by link, TOTP with backup codes. Sessions live in your own database.

Organizations and roles

Owner, admin, member — invitations by email included. Permissions and limits are checked by a single function.

Billing through Stripe

Checkout, customer portal and a trial period. The subscription belongs to the organization, not the owner's account.

Transactional email

React Email for the templates, Resend for delivery. The templates sit in the repo and preview locally in your browser.

Bilingual from line one

German and English via next-intl, locale in the path. Another language is one JSON file and one entry.

Typed and tested

TypeScript strict, migrations as readable SQL, unit tests with Vitest and two Playwright smoke tests.

Running in three steps

1
Clone and install
Pull the repository, run pnpm install. That is all the first start needs.
2
Set up the environment
Fill .env from the example file, then pnpm db:migrate and pnpm db:seed. Postgres is enough.
3
Build and ship
pnpm dev while you build, then deploy to Vercel or any other Node environment.

Common questions

Which database do I need?

Postgres. Access runs through Drizzle and the connection is a single environment variable — Neon, Supabase, RDS or a container on your machine.

Can I leave Stripe out?

Yes. Without a price ID in the config the plan catalogue stays free and Stripe is never called. Per-plan limits still apply.

Who owns the code?

You do. It is a repository you copy and change — not a library that phones home at runtime, and not an account that can expire.

Where can I host this?

Built for Vercel, but it runs in any Node environment that can reach a Postgres database.

How do I add a language?

Add a JSON file under messages and the locale code to the routing config. The route prefix follows automatically.

Are the legal pages included?

The pages are, the texts are not. They hold placeholders — do not go live without your own reviewed legal copy.
