Accounts · Payments · Email · Mobile apps
Login, payments, email, and mobile app shells, done. Hand it to your coding agent and build the part that's actually yours, not the basics every app needs.
built for coding agents
Instead of rebuilding sign-in, payments, and email every time, your coding agent starts from a foundation that already works, and spends its effort on the part that's yours.
A short guide (CLAUDE.md / AGENTS.md) tells your coding agent the one obvious way to do each thing, so it builds without guessing.
Ask for a new screen, a paid feature, or an email, and it lands complete, wired up and ready, not half-built.
The project comes with its own tests, so your coding agent can confirm a change actually works before you ever see it.
The groundwork is done, so you describe what you want in everyday words, not the technical plumbing underneath.
the essentials
Accounts, payments, and email are built and ready. Connect your own accounts to switch them on, and get back to building your idea.
what's in the box
Google, Apple, or a one-time email code
Subscriptions and one-off payments with Stripe
Sign-in codes, welcomes, and receipts
iPhone and Android app shells, from the same app
More than one person per account, from day one
Sending and processing handled for you
Export or delete an account's data on request
Sensible limits and protections already in place
Ship it to your own host when you're ready
skip the rebuild
Sign-in, payments, and email look almost the same in every app, and building them again is time and effort spent on a solved problem. One Shot hands them over done, so your coding agent puts it all into the part that's yours.
mobile apps
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.
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.
how you get it
Subscribe and you get the full code, privately, plus every update while you're subscribed. Point your coding agent at it and start building.
Everything above, ready to build on, with new updates added while your subscription is active.
A real, browsable app built on this exact foundation.
The checkout and account area you're using right now are built on it.

Get startedfrom 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 🙏
Hand your coding agent a foundation that already works, and go from idea to a prototype in one shot.
