Open it in Cursor and start building

Cursor puts the agent right in your editor. Plan mode maps out the work before any code is written, Agent edits across files and runs the commands, and you see every change as a diff before you accept it. One Shot opens as a clean, conventional codebase with the essentials already built, so you are extending a real app from the first keystroke. Cursor spends its tokens on your product, not the boilerplate.

01 / in your editor

Built to open in Cursor

Cursor brings the agent into your editor, with Plan mode for mapping the work first, Agent for multi-file edits and running the commands, and a diff for every change. One Shot gives it a solid base to read, edit, and extend from line one.

A codebase you can read

One Shot opens as a clean, conventional project, easy for Cursor to navigate.

Agent sees it all

Edit across files at once, with the whole project in context.

Diffs before you accept

Every change is shown as a diff, so nothing lands without your say.

04 / skip the rebuild

Stop rebuilding what every app needs. Sign-in, payments, and email look almost the same in every app, and building them again is tokens spent on a solved problem. One Shot hands them over done, so Cursor puts it all into the part that's yours.

iPhone and Android, from the same app

The app you build on the web is wrapped by native iPhone and Android shells, with in-app purchases already wired up. Build the part that's yours, then submit to the App Store and Google Play.

⚠ worth knowing

Apple and Google take a cut of in-app subscriptions (about 15% to 30%) and review every app before it goes live. You'll need their developer accounts.

08 / from the creator

I ship an app most weeks. It bootstraps my aerospace work and earns the passive income I live on. One Shot is the tooling I put together to make that prototyping as fast as possible for me. I hope it's as helpful for you 🙏 @wbnns

Start with key features already built

Hand Cursor a foundation that already works, and go from idea to a prototype in one shot.
