Next.js 16 · Supabase · Stripe

Launch a paid SaaS this weekend. Not next quarter.

TSC Starter is a finished, production-ready SaaS codebase. Auth, billing, a working paywall, email — already built, already tested. Open it in Claude Code, run /setup, and it configures itself.

One-time. Your repo, forever. No subscription.

Next.js 16 Supabase Stripe Tailwind v4 Resend Vercel

The difference

Most boilerplates hand you a README. This one installs itself.

Open the repo in Claude Code. Run /setup. The agent wires up Supabase, Stripe, your database schema, and your branding — while you watch.

No Claude Code? A guided web wizard does the same job: live key validation, one-click Stripe plan creation, plain-language steps. Two paths in. Pick your speed.

What's inside

The parts everyone rebuilds. Already done.

Not a skeleton. The unglamorous, time-eating plumbing of every SaaS — finished and tested.

Auth that's done

Sign-up, login, password reset — wired to Supabase. The flows you always rebuild, already built.

Billing that works

Stripe subscriptions, checkout, customer portal, webhook sync. Money in on day one.

A real paywall

Subscription-gated routes that actually gate. Free users hit the wall; paying users walk through.

Two ways to install

Claude Code /setup or a guided web wizard. Both configure the whole stack.

Transactional email

Resend wired for welcome and password-reset mail. Branded, not boilerplate.

Legal, handled

Terms, privacy, the pages every SaaS needs and nobody wants to write. Ready to ship.

FAQ

The questions you're already asking.

What's the stack? +

Next.js 16, Supabase, Stripe, Tailwind v4 and Resend. Deploys to Vercel out of the box. Modern, boring-in-the-good-way, the stack you'd pick anyway.

Do I own it? +

Yes. It's your repo. Build and sell whatever you want on top — no royalties, no strings, no per-seat fees.

Is it actually finished, or another skeleton? +

Finished. It was smoke-tested end to end against real Supabase and Stripe: sign-up → paywall → checkout → subscription sync. The hard parts work before you touch a line.

Another boilerplate — why this one? +

Because it installs itself, and it's actually done. Most starters hand you a setup checklist. This one runs the setup for you and ships with the billing, paywall and auth already wired.

Do I need Claude Code? +

No. The guided web wizard does everything /setup does — live key validation, one-click Stripe plans, plain-language steps. Claude Code is just the faster path if you have it.

What about updates? +

Included. You keep access to the private repo, and updates land there. Pull when you want them.

Refunds? +

It's source code — once you have repo access, you have the product. If /setup genuinely won't run and we can't fix it together, email me and I'll refund you.

How do I get support? +

Email hello@thescalablecreative.com. Builder to builder — real answers, not a ticket queue.

Stop rebuilding auth. Start shipping.

The plumbing is done and tested. The install runs itself. The only thing left is your product.
