Describe your Shopify app.
Watch it fly.
AppFly turns a plain-English description into a working Shopify app — OAuth, Admin API, webhooks, extensions, Polaris UI and billing wired up — then deploys it under your own Partner organization.
No credit card. Your code, your Partner account.
On it — building Restock Alerts.
- Scaffolded app with Shopify CLI
- Wired OAuth + session storage
- Added inventory_levels/update webhook
- Built Polaris settings page
- Adding usage-based billing plan
Restock Alerts
ActiveNotify staff when inventory falls below threshold.
Files written
- Mapp/routes/app._index.tsx
- Aapp/routes/webhooks.inventory.tsx
- Aapp/lib/alerts.server.ts
- Mshopify.app.toml
How it works
Idea → built → deployed
That's the whole flight path. Three steps, one browser tab.
Describe it
Write what the app should do in plain English. No boilerplate, no starter template to fork, no Shopify docs tab open.
AI builds it
The agent creates and edits files, runs commands, reads errors and iterates — producing a real Shopify app you can open and read.
Ship it
Connect your Shopify Partner account and deploy to development or production under your own organization, via the Shopify CLI.
Shopify-native
It knows the platform, not just the language
General-purpose AI builders produce a React app. AppFly produces a Shopify app — with everything the platform requires already in place.
OAuth, done right
Install flow, scopes, session storage and token refresh are generated correctly the first time — the part everyone gets wrong.
Admin & Storefront APIs
Typed GraphQL queries and mutations against the current API version, with pagination and rate limiting handled.
Webhooks & HMAC
Subscribe to topics, verify signatures, handle retries and process events idempotently — registered in your app config.
Extensions
Checkout UI, admin blocks, theme app extensions and Shopify Functions, scaffolded and wired into your extension directory.
Billing
Recurring plans, usage charges and free trials through the Billing API, including the approval redirect merchants expect.
Shopify CLI native
The agent runs the same CLI you would — dev, deploy, app config link — so nothing about your project is proprietary.
The agent
A coding agent, not a code generator
AppFly doesn't hand you a one-shot file dump. It works the way a developer works — writing, running, reading errors and fixing them — inside a browser editor with live preview and AI chat side by side.
- Creates and modifies files across the whole project
- Runs commands and reads the output
- Debugs failures and iterates until it works
- Explains every change in plain language

Deploy
Ships under your name, not ours
AppFly is the infrastructure between your idea and the Shopify App Store. What comes out the other side is yours.
Your Partner organization
Connect your Shopify Partner account once. Apps are created and deployed under your org — you own the listing, the clients and the revenue.
Dev and production
Iterate against a development store with live preview, then promote the same app to production when the build is green.
No lock-in
It's a standard Shopify app on disk. Export it, push it to your own Git remote, and keep working in your own editor whenever you want.
