Spec
Brief in, spec out
Write a few lines about your AI chat app. We turn them into a clear spec, and nothing builds until you approve it.
AI SaaS builder with launch checks
Brief. Build. Ship.
Describe who pays, the problem, and your price. We write the spec, build a Next.js app with sign-in and checkout, and take it live only after every launch check passes. You keep the full source.
Signing up is free. Writing a brief, building and going live need a paid plan, from $29/mo.

What you get
Everything between brief and live
One clear path from idea to launch, and everything we build is yours to export.
Launch checks
Live only when it's ready
Sign-in works, checkout is present, secret keys stay out of the browser. The app goes live once every launch check passes.
Ownership
The source is always free
Download the full source with its launch-check report any time. Your sales stay yours.
Stack
One proven stack
Every app runs on Next.js, Better Auth, Polar billing and a Neon database, so nothing is improvised per app.
Preview
A live URL before you commit
Every build gets a hosted preview on whatasaas.com. Factory can use your own domain.
How it works
Four steps: write a brief, approve the spec, we build it, it goes live once every launch check passes.
STEP 1
Brief
Describe your AI chat app in a few lines: who pays, the problem it solves, and the price.
STEP 2
Spec
We turn your brief into a spec: screens, pricing, sign-in and data. Nothing builds until you approve it.
STEP 3
Build
We build from a tested template with sign-in, checkout, and error tracking already wired. API keys never reach the browser.
STEP 4
Go live
Every launch check must pass before the app goes live on its whatasaas.com address. Factory plans can use their own domain.
