One prompt · full SaaS

Describe your SaaS. We build the whole thing — auth, billing, dashboard, API.

SaaS Builder is Platform's specialized mode for product-shaped builds. You get a multi-tenant Next.js app with Supabase auth, Stripe Checkout + Customer Portal, role-based dashboards, admin console, public marketing site, and a typed API. Deployed in <5 minutes. Receipt-signed. Yours to own.

FAQ

Common questions.

Do I own the code?

Yes — on the Own plan you get the GitHub repo (MIT-licensed for your use), full source, no telemetry, no kill-switch. Host on Vercel, Fly, Cloudflare, AWS — your choice.

Can I customize after the initial build?

Yes — chat with DCS Edit (built-in) to add features by description, or open the repo in any IDE and write code yourself. The Visual Editor handles non-code changes.

What's the difference between SaaS Builder and Platform?

Platform builds general websites (restaurant, salon, agency). SaaS Builder builds *products* — multi-tenant apps with login, billing, dashboard. Different defaults, same underlying agent swarm.

How are receipts useful for a SaaS?

Every signup, plan change, refund, admin action emits a signed receipt. For B2B SaaS selling into regulated industries, you can hand a customer a CSV export of every action taken on their tenant — independently verifiable. Audit trail by default.

Can I use this for a side project?

Absolutely. Try plan is free, you get a real working SaaS on a dcsai.app subdomain. Upgrade only if it starts making money.
