Plain English in.
Native machine code out.

No interpreter. No runtime. No packages. One binary that imports a single system library — and whole classes of attack that aren't filtered here, because they can't be written.

Free credits to start. No card needed.

What you actually get

Not a description of the process. The thing that lands on your machine.

Unwriteable, not filtered

No operation can name a file, a host, a port or a table. SQL injection, SSRF and path traversal aren't blocked here — they can't be written in the first place.

  • Native machine code

    Real x86-64 machine code. No interpreter and no runtime to ship alongside it. What you download is the program.

  • One system library

    The binary imports kernel32.dll and nothing else. No packages, no supply chain, nothing to keep up with — open it with any PE tool and count the imports yourself.

  • Come back to it later

    Every build gives you a receipt: the input that made it. Feed the receipt back and rebuild the same app from the input you gave.

What it doesn't do

Worth knowing before you start, rather than after.

  • It needs somewhere to run

    What you get back is a web app. It is a binary you host, not something that starts on its own when you double-click it.

  • It doesn't remember anything yet

    A build runs, answers, and keeps nothing between visits. That is every plan today, not just the free one — nothing is stored and nothing reaches another service.

  • Download links expire

    The links last about an hour. After that, build again — the app is unchanged, the link is not.

  • Web apps, as Windows binaries

    Today it builds web apps, and what you download is a Windows x86-64 executable. The preview runs anywhere — it is only the download that is Windows-only for now.

  • It isn't checked for correctness

    Nothing here proves your app does what you meant. That part is still yours to judge, which is why the preview is there before you download a thing.

On the way

Not here yet. These are new targets on a design meant to take them, rather than a rebuild.

  • Linux and macOS

    The same build, targeting more than Windows.

  • More than web apps

    Console apps and other shapes, alongside the web apps it builds today.

  • Step through it

    Read and step through your app in C, C#, PHP or Python, and send your edits back as input.

  • Apps that remember

    Stored data, accounts, and a record of what changed — the parts that need a database behind the page.

How you use it

The loop, once you are in. Change a word and run it again.

  1. 01

    Say what you want

    Plain words, a sentence or two. What the app does, and who uses it. No setup, no boilerplate, no framework to pick.

  2. 02

    Watch it come together

    When it comes back you get the shape of it — the pieces it needs and how they connect — next to a live preview you can click.

  3. 03

    Take it with you

    Download the binary and its support files. Where it runs is your call. It is yours to host, to keep, to change.

What would you build first?

A minute or two, and your first builds are on us.
