PROMPT → PRODUCTION · UNDER 30 MIN

Say it once.
Ship it live.

Plain English goes in. A production web and mobile app comes out — real sign-in, real card payments, real hosting. Nothing to install, nothing to wire.

From one description
SHIPPING WITH PROTOFAST
ThePlotOffTheLoop

Three steps. One of them is yours.

You describe. The swarm designs, builds, wires and deploys. That is the entire workflow.

01

Describe it

Explain it like you would to a developer friend. No specs, no wireframes, no tickets — the sentence is the interface.

02

Agents build it

Data model, API, UI, auth and payments get split across specialised agents working in parallel — and you watch every decision land.

03

It's live

Production hosting, a shareable URL, sign-in that works and payments that can charge a real card. Same half hour.

The prompt fans out to five agents (Architect, UI, Payments, Auth and Deploy) building in parallel, which converge on the live app at its protofast.app URL

A real product, not a clickable mockup

Everything a launchable app needs is in every build — not an add-on you bolt on next quarter.

Parallel
A swarm, not a queue

Architecture, UI, API and infra agents build concurrently. That's why minutes, not months.

Accounts
Auth out of the box

Sign-up, sessions, password reset — wired from the first build. Testers log in like it's a real product.

Revenue
Payments built in

Subscriptions, checkout and billing pre-integrated. Flip off test mode and it takes real money.

Reach
Web and mobile, one prompt

Every build ships a responsive web app and a mobile-ready experience together.

Hosting
Production from minute one

No localhost, no staging purgatory. Managed hosting with TLS the moment the agents finish.

Iteration
Change it by chatting

"Make the dashboard dark." "Add referrals." Live in minutes — feedback loops measured in coffee sips.

What 30 minutes actually looks like

Not a demo-day estimate — the clock on a typical build, from submit to a URL you can text a friend.

0:00
You hit Prototype it

The planning agent drafts the architecture.

0:02
The swarm fans out

UI, API, data, auth, payments in parallel.

0:12
First working preview

Click real screens while the backend wires up.

0:22
Auth and payments green

Accounts sign in, test cards charge, hooks fire.

0:28
Deployed to production

A shareable URL with TLS, ready for users.

Build timeline from 00:00 to 27:58, one timestamped event per agent, ending on a card with the app's live URL
“I described the app over lunch. By the time I finished the sandwich, customers could sign up and pay. I've had sprints deliver less than that sandwich.”

Your next idea could be live before this meeting ends.

Describe it once. Get a production app with sign-in, payments and a shareable URL — in less time than a standup that ran long.
