Welcome to Appsanic
Appsanic builds phone apps. You describe the app you want in plain English. An AI agent plans it, writes it, and streams a live version onto your phone while you watch. When you're ready to go live, you connect your store account and click Publish, and Appsanic builds your app in the cloud and uploads it to the App Store and Google Play for you. Prefer to drive it yourself? You can always export the project to your own GitHub repo and run the standard Expo build tooling (EAS) instead.
You never have to write code. If you know how to, you can.
Hit a word you don't know? These docs have a Glossary with plain-English definitions of every technical term: API, backend, push notification, all of it. You don't need to read it cover to cover. Just open it whenever something looks like jargon.
Who this is for
If you've never built an app before. Good. That's exactly who Appsanic was built for. You don't need a Mac. You don't need anything called Xcode or Android Studio. You don't need a terminal. You don't need to install anything except a free app on your phone called Expo Go, which is what shows you the live preview. Read the Quickstart next. It walks you through building your first app, with nothing assumed.
If you've launched apps before. Everything Appsanic produces is real React Native with TypeScript, wired through Expo, with a Supabase backend. There's a Monaco-based code editor inside the builder, a real git history, and a one-click export to your own GitHub repo. Skim Writing Prompts and Fast vs Pro, then jump straight to the Connectors Overview.
What actually happens when you type a sentence
You write a description. Then:
- The agent reads what you asked for and writes itself a plan: the screens, what data gets stored, which services to plug in, what edge cases to handle.
- You read the plan and approve it (or adjust it in plain English: "actually, skip payments. And use sign-in-with-Apple, not passwords.")
- The agent builds the whole app, file by file. Every screen, every piece of boilerplate.
- A live preview streams to your phone via the free Expo Go app.
- You poke, tap, send feedback. The agent iterates.
- When you're ready to go live, you open the Publish dialog, connect your store account, confirm your app details, and click Publish. Appsanic builds the release in the cloud and uploads it for you - iPhone to TestFlight, Android to your Play internal testing track. No Mac and no command line. Prefer to drive it yourself? You can still export to GitHub and run EAS by hand.
Steps 1-5 happen without you installing anything on your computer. Just a browser tab and your phone.
Publishing through Appsanic is rolling out. The one-click flow below is how it works: you connect your store account, click Publish, and Appsanic builds and uploads your app for you. While we finalise it, if it is not yet enabled on your account you can publish today by exporting your code and running EAS yourself. We will remove this note when the flow is live for everyone.
What you keep
One thing up front: the app is yours. Not ours.
- Your code lives in a GitHub repository under your name.
- Your backend (Supabase) is in your account with your login.
- Your users' data belongs to you, not Appsanic.
- Your App Store listing is published under your own Apple Developer and Google Play accounts. Appsanic builds and uploads on your behalf using a revocable key you control - never a password - and you can export and run EAS yourself any time.
If you cancelled Appsanic tomorrow, your app would keep running. No lock-in, no data ransom, no migration pain.
What you need to get started
- An idea you can describe in a paragraph.
- A phone (iPhone or Android) to preview on.
- An email address.
You do not need:
- A Mac. Windows, Linux, and Chromebook all work.
- A code editor, Xcode, Android Studio, Node, or anything installed locally.
- Any coding knowledge.
The free tier doesn't require a credit card.
What publishing costs
Publishing a real app to Apple and Google has a little bit of real-world admin, no matter who built the app. When you get to that point:
- Apple Developer account ($99/year), required to publish on iPhone.
- Google Play developer account ($25, one-time fee), required to publish on Android.
Those are Apple and Google's fees, not Appsanic's. Publishing through Appsanic is a paid-plan capability (Pro and Business): the Publish dialog shows the exact credit cost before you confirm, with indicative figures of around 30 credits for iPhone and 15 for Android - each publish targets one store, so being on both stores is two publishes, about 45 credits in total (pricing is set server-side, so the dialog is authoritative). The App Store and Google Play guides walk you through connecting your store account and the console paperwork step by step.
The honest part
Appsanic is an agent, not magic. The first build of your app is usually 85-95% of what you want. The rest comes from talking to it:
- "The font is too small."
- "Add a dark mode."
- "The streak should roll over at midnight in the user's local timezone."
Each of those is a minute of back-and-forth, not a day. And the agent is transparent: you can read every decision as it makes it, open any file to see the code, and roll back anything that looks off.
Start
Open the Quickstart. In about fifteen minutes, you'll have a real app running on your phone.
