Build a custom Shopify app by describing it
AppFly is the AI Shopify app builder. Describe the app you want — it writes the code, installs it on your store, and hands you a real Shopify app. No coding needed.

What you can build
One prompt, seven kinds of Shopify app
AppFly knows the rules of each surface — the scopes it needs, where it installs, how it is registered — and writes for it directly. Name the one you want.
Surface 1: An admin page
A page inside your Shopify admin — reports, tools, bulk edits.
Surface 2: A storefront block
A block you place on your storefront in the theme editor.
Surface 3: A discount rule
A discount rule that runs in Shopify's checkout.
Surface 4: A checkout block
A block in checkout or on the thank-you page — upsells, notes, trust badges.
Surface 5: A customer account page
A page or block in your customers' account — loyalty, returns, wishlists.
Surface 6: A Flow automation step
A step you can use in Shopify Flow automations.
Surface 7: A point-of-sale tile
A tile and screen in Shopify POS for your in-person staff.
How it works
Three steps, and the second one is the product
A coding agent writes your app into a container you can watch. You are not waiting on a queue — you are reading the build.
Step 1: Describe it
One sentence. “A bulk editor that lets my team retag 500 products at once.” If you want to narrow it first, AppFly asks a few questions before it starts writing anything.
Step 2: Watch it build
A real coding agent writes a real project into a real container. Files, commands and installs stream to the screen as they happen — not a progress bar with a timer on it.
Step 3: Iterate, then ship
Ask for changes in the same panel as the preview. When it is right, deploy it: your app gets its own subdomain, its own database and its own entry in the Shopify admin.
Pricing
Start free. Pay when you ship.

FAQ
The questions we get asked
Do I need to know how to code?
No. Everything you do is a sentence: describe the app, then describe the changes. The code is generated, installed and run for you, and if something is wrong with it the fix is another sentence rather than a hiring process.
Whose AI account does the building run on?
Yours. You connect Claude Code, Codex or OpenCode with the account you already have, and the agent you pick is the one that writes the app. Your plan's monthly ceiling caps how much agent work your apps can do, so the bill stays bounded.
Who owns the code?
You do. An app is a normal project on disk, not a lock-in format. You can read every file, and you can take the app and run it yourself. The only thing AppFly keeps is the running container, and that is a convenience, not a licence.
Do you store my customers' data?
No. AppFly holds your account, your store domain, the prompts you wrote and the apps built from them. It never reads your store's customers, and the access scopes it asks Shopify for do not include them. A Shopify customer-data request receives a reply that says so.
What happens to my apps if I delete my account?
They are deleted: the container, the database, the files on disk, the deployment, its DNS record and its session. Deletion is queued and retried until it succeeds, so a teardown that fails halfway does not leave an orphaned database running.
What happens if I uninstall the Shopify app?
Everything belonging to your shop is erased within 48 hours, including every generated app and its database. That is the same window Shopify requires, and it is enforced by a scheduled sweep as well as by the uninstall handler.
Can I use it in the Shopify admin, or do I have to leave it?
Either. AppFly runs embedded in the Shopify admin, where the app it builds installs into the same admin, and it runs as a standalone app at this address. Same accounts, same apps, same code.
What does it cost?
A free plan that builds one app and previews it. Paid plans start at $29 a month and add production deploys, more apps and more agent budget; 20% off when you pay yearly. The full list is on the pricing section above.
