Ship the product, not the demo.
Auth, database, roles and deployment are there from the first prompt — a React frontend on a Python backend with its own PostgreSQL. Tested before every release, and the code is yours to take with you.
A prototype does not survive your first ten customers
Prototype-first tools get you to a convincing screen fast. The trouble starts on the day someone logs in, pays, or asks where their data is — because that is a backend question, and a prototype does not have one.
Airbuild generates the whole thing at once: interface, Python API, PostgreSQL schema with real constraints, authentication and roles. What you demo on Friday is what runs on Monday, and it keeps running once the tenth customer arrives.
What you get from the first prompt
The weeks normally spent on setup, before any of your product exists.
Full stack, not a front end
React and FastAPI with a managed PostgreSQL — foreign keys, constraints, Decimal money, UTC timestamps — plus authentication and team roles.
Tested before it ships
Tests are generated alongside the code, and a security and quality gate runs on every publish. High-severity findings block the release rather than reaching your users.
No lock-in at the raise
Standard exportable code, your own GitHub repository, self-hostable. Nothing about the application depends on us still being in the picture.
Idea to running product
The same four steps for the MVP and for everything you add after it.
Describe it
Write down what the product does — or bring notes, a spreadsheet or an existing spec and let Airbuild read them.
Review the plan
Data model, screens and API surface are laid out before a line is written, so corrections are cheap.
Generate and test
Frontend, backend and database are built together, with tests, and build errors are repaired as they appear.
Publish and iterate
One click to your own domain. The next change takes the same path and lands as a real Git commit.
What you keep when you outgrow us
The question every founder should ask a builder tool before committing to it: what exactly do I walk away with?
- Standard React and Python you can run on your own infrastructure
- Your own GitHub repository, with the full commit history
- An export of your application database on request
- EU hosting with EU data residency, GDPR-native
- Free to start: 250 AI Tasks in your first month with a business email address
Questions founders ask
How much can I actually build on the free plan?
The free starter month is sized to finish a real project rather than to try one: 250 AI Tasks in your first month when you sign up with a business email address, with no daily limit inside that window. Signups with a freemail address start with 50. After the first month every free account continues with 50 AI Tasks a month, at most 25 a day. An AI Task is a completed generation — a new page, a bug fix, a refactor — not every small edit.
What happens when we hire our first engineer?
They get a normal repository with normal code: React on the front, FastAPI and PostgreSQL behind it, migrations included. Connect your own GitHub repository (Website Builder Pro and above) and changes are committed and pushed there automatically, so the codebase already lives outside our infrastructure on their first day.
Can we take payments?
Yes — a Stripe checkout is generated on request as part of the application, the same way auth and roles are. It is your Stripe account and your keys.
Is the generated code good enough to raise on?
It is production-shaped: a real schema with constraints, generated tests, and a security and quality gate on every publish. What the gate does not prove is that your authorization rules are right — who may read which record is your application’s logic, so budget a review for anything handling sensitive data before you scale.
