The short verdict
Rork is the better pick for a founder who wants a native Swift iPhone app and a Kotlin Android app with publishing from inside the tool, and a0.dev for one who wants a React Native app with built in over the air updates and paywalls. OneCraft suits a small business that wants one Expo app written around its services, with bookings, members or orders in its own database, for less per month.

Where Rork is better
Fully native code
Rork writes Swift with SwiftUI for iPhone and Kotlin for Android. OneCraft writes one Expo and React Native codebase for both.
Publishing from the tool
Rork's docs describe pressing Publish and entering a verification code to send the app to Apple. OneCraft never submits; you use eas submit from your own accounts.
Where a0.dev is better
Over the air updates
a0.dev ships updates to all platforms without a rebuild or a new store review. OneCraft's documented route to phones is a new Expo build.
In-app purchases on iPhone
a0.dev sets up subscriptions through the Apple App Store on iOS. OneCraft takes card payments through Stripe Checkout only.
Where OneCraft is different
Built for a business, not a consumer app
The agent plans tabs, an Account tab and screens for services such as classes, bookings and members, using 65 capability guides that build those features into the app's own database.
Access rules checked by the agent
Every table gets row level security, and the agent checks each new table as an anonymous visitor and as a signed in person before a build step can finish.
A website from the same account
OneCraft also writes React Router websites, and an app can be based on one of them so both share a database, colours and content.
Three different bets on the stack
Rork moved from Expo to native code, saying its agent writes better Swift apps, so an iPhone app and an Android app are now two codebases in one project. a0.dev keeps a React Native workflow, testing in its own app or Expo Go. OneCraft writes Expo with Expo Router and React Native Reusables: one codebase, built for iPhone and Android through Expo's build service, which any React Native developer can pick up.
Publishing and updates
Rork and a0.dev both connect to your App Store account and push the build for review from inside the tool, and a0.dev adds over the air updates. OneCraft stops one step earlier: it runs a test build or a store build for 5 credits on a paid plan, and you submit with eas submit. Apple's developer programme costs 99 USD a year and Google Play 25 USD once in every case.
Paying for the work
Rork Pro is $20 a month for 100 credits, with iOS builds and cloud simulator time charged on top. OneCraft Starter is $8 a month for 500 credits; a measured whole app generation used 55 to 72 credits and each Expo build adds 5.
Who should stay with Rork or a0.dev
Stay with Rork if you want separate native Swift and Kotlin apps and publishing from inside the builder, or with a0.dev if over the air updates and App Store subscriptions matter most. Move if you run a service business and want one Expo app with its bookings, members and payments written into a database you control.
Questions people ask
Can OneCraft write a native Swift app?
No. OneCraft writes React Native with Expo, which compiles to native iPhone and Android apps from one codebase. If you need Swift and SwiftUI specifically, for example to hand the code to an iOS team, Rork's native output is the closer fit.
Can I move a Rork or a0.dev project into OneCraft?
There is no importer. You can base a new OneCraft app on a web address so the agent reads its content and look, but the app is written again from your brief rather than converted file by file. Rork's docs describe imports into Rork from other builders through GitHub.
Does OneCraft use Supabase like Rork and a0.dev?
Yes. A site's data lives in Supabase, either as a schema in OneCraft's pool on every plan or as a project on your own Supabase account, with migrations and a schema file kept in the app's repository.
Which builder is cheapest to start?
All three let you start free. OneCraft's free plan generates and previews apps with 100 credits a month but cannot run Expo builds; Rork's free plan designs but does not build; check a0.dev's pricing page in a browser for its current plans.
Can members sign in with Google in a OneCraft app?
Yes, through OneCraft's Google sign in broker, alongside email and password with password reset. Google sign in works in the installed app and on the published website, but not in the builder preview. Rork's docs describe Google and Apple sign in through Rork Auth.
