Wholestack turns a plain-English prompt into a complete, verified SaaS app — auth, multi-tenant database, billing, realtime, and UI — then blocks anything it can't prove safe with ShipGate. Build from Intent. Ship with Proof.

Hey Product Hunt 👋 — maker here.
I built Wholestack because I got tired of the most dishonest sentence in software: "✅ Done! Your app is ready."
Every AI app builder says it. None of them know it. Earlier this year, security researchers found 170+ AI-generated apps with their databases fully exposed — emails, payment records, home addresses
— because the AI "finished" apps that were never actually checked. And we've all watched an AI burn $40 of credits looping on one bug it kept reintroducing.
So we built the opposite: an app builder that has to prove your app works before you can ship it.
One sentence in → a complete app out (real Postgres + row-level security, auth, payments, dashboards, its own design). Then, before you ever see "done," every build passes through ShipGate:
- Does it actually compile? (real exit codes, not vibes)
- Can one user see another user's data? (we attack the live database and try)
- Is every mutation behind auth? (checked in the code, not promised)
- Any secrets left in the source? Fake success screens?
Pass → you get a signed certificate with the evidence. Fail → it says NO_SHIP and tells you exactly why — it fixes itself and re-proves, and you don't pay for that loop. The gate is fail-closed: if
something can't be proven, it doesn't pretend.
The honest part: no tool can prove an entire app correct — that's a math limit, not a missing feature. We prove the parts that ruin you (data isolation, auth, money math), generate the rest, and
draw a visible line between the two.
Pricing is one we wish more tools had: $25 for a finished app — not tokens you burn watching a spinner. Free tier to try it; you only ever pay for verified results.
I'll be here all day — ask me anything, especially the hard stuff. If you want to try to break a generated app's tenant isolation, genuinely: please try. That's the whole point.
