Facts

Everything this site claims about sup3rapp, in one place, with the scope of every measurement stated. If another page on this site disagrees with this one, this page is right and that page is a bug.

What sup3rapp is

sup3rapp is an AI app builder that verifies the application it generates — typecheck, tests, a production build and a smoke test — before the preview reaches you.

Category: AI app builder. Availability: sup3rapp is in private beta. Access is by request; there is no self-serve signup yet. No date has been announced for general availability.

The verification chain

Every build runs the same chain, in this order: typecheck → tests → production build → smoke test. A failure at any stage triggers an automatic repair loop and the chain re-runs from the top. The preview is released only when the chain passes.

Wall-clock for one full verification chain, measured on our marketing-site scaffold in a network-less sandbox. The four stages account for 36.4s of it; the remainder is the sandbox handoff between stages. These are measurements of one scaffold under one set of conditions, not a promise about your application.
Stage	Measured	Scope
typecheck	4.2s	measured on the marketing-site scaffold, in a network-less sandbox
tests	4.3s	measured on the marketing-site scaffold, in a network-less sandbox
production build	24.0s	measured on the marketing-site scaffold, in a network-less sandbox
smoke test	3.9s	measured on the marketing-site scaffold, in a network-less sandbox
full chain	37.4s	wall-clock, measured on the marketing-site scaffold in a network-less sandbox

Every build is verified before you see it: typecheck, then tests, then a production build, then a smoke test.
shipped capability · verify-before-preview
A verification failure triggers an automatic repair loop rather than an error message. The chain re-runs from the top.
Structured diagnostics from the failing stage are fed back for a bounded number of repair attempts before anything surfaces to the user.
shipped capability · repair-loop
You see a working application or you see honest progress. A failed chain never reaches you as a broken preview.
shipped capability · no-broken-preview

Execution and isolation

Generated code runs in a per-project isolated sandbox. That includes the preview.
shipped capability · per-project-isolation
Untrusted generated code never executes on shared infrastructure, and never shares infrastructure with another project.
shipped capability · no-shared-infra

Versions and rollback

Every build produces an immutable, content-hashed version. Iterating creates a new version; nothing is edited in place.
shipped capability · immutable-versions
Rolling back is a pointer change to an earlier version, not a rebuild — so it is instant and cannot fail.
shipped capability · pointer-rollback

How the model changes code

The model proposes structured file-edit operations. A deterministic executor validates them and applies them atomically — all of them or none.
shipped capability · structured-edit-ops
The model never touches a filesystem or a network directly.
shipped capability · no-model-fs-network
Generation starts from a pre-built, tested scaffold rather than an empty directory. The model modifies working software; it never invents project structure.
shipped capability · scaffold-start

Scaffolds

Generation starts from one of these, not from an empty directory. Each is a real, tested application that the model modifies.

The three scaffolds available at the time of writing.
Scaffold	What it is	Ships with
marketing site	A landing page, a lightweight content model, and contact forms.	routing, content model, contact forms, design tokens, a passing test suite
SaaS starter	Authentication, a Postgres schema, a dashboard shell, and billing wiring.	auth, Postgres schema, dashboard shell, billing wiring, a passing test suite
internal tool	CRUD tables, filtering, and role-based access.	CRUD tables, filtering, role-based access, design tokens, a passing test suite

Pricing

sup3rapp is charged per build operation. Prices are not published while the product is in private beta, and this site does not quote a number it cannot stand behind.

You are charged per build operation, not per token — for work completed, not for the model’s verbosity.

Goals, stated as goals

These are engineering targets. They are not shipped product metrics, and they do not appear anywhere on this site as promises.
