How to Create a Custom Shopify App Without Coding
A custom Shopify app used to mean hiring a developer. Today there are several ways to get one without writing code — but they are not interchangeable. Some only work in your admin, some are automations rather than apps, and some build the full thing. Here is how to pick the right route for what you need.
What “custom Shopify app” means
A custom app is built for one store — yours — rather than sold to thousands of stores on the Shopify App Store. It uses Shopify's APIs to do exactly what your business needs: a report in your own format, a rule that matches your pricing, a block that says what your customers need to hear.
One source of confusion: Shopify lets store owners set up custom app credentials for API access. Those credentials are a key, not an app — something still has to be written that uses them. The no-code routes below are about getting that something without writing it yourself.
Not sure whether you need a custom app at all? Read custom app vs. App Store app first.
Route 1: Shopify Sidekick app generation
Sidekick, the AI assistant built into the Shopify admin, can generate simple apps from a description. Shopify's help center describes them as single-page tools that live in your admin and use the Admin API — for example, reorder recommendations or a discount-link generator.
- Good for: quick internal tools on the Grow, Advanced or Plus plans.
- Limits: generated apps only work inside the admin, so they cannot add anything customers see — no storefront, checkout or customer account features. Generation needs a desktop browser and has hourly and weekly usage limits.
Route 2: Shopify Flow
Shopify Flow is Shopify's no-code automation tool: when something happens (an order is placed, inventory drops), check a condition, then take an action (tag the order, send an email, hide a product). It is not an app in the sense of a screen or a block, but it solves many problems people first try to solve with one.
- Good for: “when X happens, do Y” rules using Shopify's built-in triggers and actions.
- Limits: no custom screens, reports or customer-facing features, and you are limited to the actions Flow and your installed apps provide. A custom app can add new actions to Flow — AppFly builds Flow steps for exactly that reason.
Route 3: An AI Shopify app builder
An AI app builder writes a complete custom app from a plain-language description, installs it on your store and hosts it. AppFly is one: a coding agent writes a real project, and you change it by chat.
- Good for: anything Shopify's app platform allows across seven surfaces — admin pages, storefront blocks, discount rules, checkout blocks, customer account pages, Flow steps and POS tiles — including scheduled jobs, webhooks and connections to services like Stripe, Klaviyo or Slack.
- Limits: like any app, it works within what Shopify's APIs allow. Very large integrations with undocumented private systems may still need a developer.
- Cost: free to build and preview one app; production deploys start at $29 a month, hosting and a database per app included.
Which no-code route should you use?
- “I want a quick tool in my admin and I'm on Grow or above.” Try Sidekick.
- “When something happens, I want something else to happen automatically.” Start with Shopify Flow.
- “Customers should see it” — a storefront block, a checkout or thank-you page block, a customer account page. Use an AI app builder.
- “It changes how prices or discounts are calculated.” That is a Shopify Function; use an AI app builder.
- “It needs its own data, runs on a schedule or connects to another service.” Use an AI app builder.
- “My Flow automation needs an action that doesn't exist.” Build a custom Flow step with an AI app builder and keep the rest in Flow.
Create your first custom app in five steps
Here is the short version with AppFly. The full step-by-step tutorial goes deeper on each step.
- Pick one problem. A chore someone does every week is ideal — a report, a bulk edit, a message that should change by itself.
- Choose where it lives. Pick the surface from the dropdown under the prompt box, or say it in your sentence.
- Describe the outcome. “A page in my admin that shows yesterday's sales, refunds and top five products, for me, every morning.”
- Preview and refine. The app runs against your store; ask for one change at a time.
- Deploy. The app gets its own subdomain, database and entry in your Shopify admin.
What to check before you rely on it
- You own it. Make sure you can read and export the code. With AppFly the app is a normal project you can take and run yourself.
- It only reads what it needs. Look at the access scopes it requests when it installs.
- You know what happens when you leave. In AppFly, uninstalling erases everything belonging to your shop within 48 hours; the security page has the details.
Frequently asked questions
Can I create a custom Shopify app without coding?
Yes. Shopify Sidekick can generate simple admin-only apps on eligible plans, and AI app builders like AppFly create complete custom apps — including storefront, checkout and discount features — from a plain-language description.
Is Shopify Flow a custom app?
No. Flow is Shopify's automation tool for “when this happens, do that” rules. It has no custom screens or customer-facing features, but a custom app can add new actions to it.
Do I need Shopify Plus to create a custom app?
No. Custom apps are not a Shopify Plus feature. Some features have plan rules of their own — checkout UI extensions inside the checkout steps require Shopify Plus, while the thank-you and order status pages are available on all plans.
How much does a no-code custom Shopify app cost?
Sidekick is included in eligible Shopify plans and Flow is free on most plans. AppFly is free to build and preview one app, with production plans from $29 a month.
