# Next.js SaaS starter with PostgreSQL

Your Next.js SaaS needs a real data layer. The PostgreSQL adapter includes user records, waitlist patterns, and billing-friendly schemas you can swap later without rewriting helpers.

## The problem

A Next.js SaaS with PostgreSQL sounds simple until you need user records, verification tokens, and billing state in the same schema with swappable helpers.

Scaffold Next.js, find a PostgreSQL tutorial, wire env vars, fix auth sessions, then repeat for billing and email. Most teams lose weeks before the stack deploys cleanly or handles real users.

## Why LaunchFast

LaunchFast is a production Next.js repo where PostgreSQL already talks to auth, billing, and deployment. Add your keys, customize the UI, and ship while the cross-cutting SaaS plumbing stays done.

### Benefits

- SQL helpers for users and billing state
- Works with Neon, Xata, Supabase, or self-hosted Postgres
- Swap providers with env changes

## How it works

### Clone and configure

Add your PostgreSQL keys and provider settings to the included env template. The Next.js app boots with the integration active.

### Customize product flows

Adjust pages, pricing, and onboarding on top of pre-wired routes. Auth, webhooks, and integration helpers stay intact.

### Deploy with included configs

Use the bundled Vercel, Cloudflare Workers, or Node deployment setup. Sessions and webhooks are tuned for production, not just localhost.

### Swap providers later

Client wants a different payment processor or database? Change adapters through config instead of rewriting your Next.js app.

## FAQ

### Is this only about PostgreSQL?

No. The Next.js kit is a complete SaaS foundation. PostgreSQL ships alongside auth, billing, email, analytics, storage, and deployment so you are not assembling the stack from scattered tutorials.

### Can I see it working before I buy?

Yes. The live demo runs the same Next.js starter with real auth and billing flows. Open the demo, click through signup and checkout, then compare with your timeline.

### What if I need Astro or SvelteKit instead?

LaunchFast ships the same integration surface in all three frameworks. Related links on this page point to the PostgreSQL guides for Astro and SvelteKit too.
