Custom Shopify
App Development

Types of Shopify apps we develop
At Mageplaza, we build the kinds of Shopify apps that help your store work the way you need it to—more efficient, more flexible, and ready to grow with you:
Public apps
If you're offering a solution that other Shopify merchants could use too, a public app is the way to go. These apps are listed on the Shopify App Store, giving you access to a huge audience and instant credibility.

Custom (private) apps
Sometimes, your store needs something specific—something no existing app can do. That’s where custom apps come in. We build private apps tailored to your exact business needs, whether it's syncing data, automating workflows, or solving one-of-a-kind problems.
Headless & mobile apps
Looking to give your customers a faster, smoother, and more flexible shopping experience? Headless and mobile apps let you customize every part of your storefront, while still using Shopify’s powerful backend. We build headless setups that load fast, look great on any device, and give you full control over how your store feels.
POS-integrated apps
Selling in-store and online comes with challenges—disconnected data, inconsistent stock, and missed opportunities. Our POS-integrated apps solve that by connecting your physical locations to your Shopify store. Inventory, customer profiles, and orders stay in sync so your business runs smoother on all fronts.
Our Shopify app development services include
Custom app development
Mageplaza helps you build exactly the app your business needs. We can get your MVP up and running fast—so you can test ideas quickly—or develop a full-scale solution that’s secure, powerful, and built to grow with you. You just bring the vision, we’ll handle the tech.
UX/UI design
Your customers deserve a smooth, beautiful experience—and that’s exactly what we create. By following Shopify’s design best practices, including the Polaris design system, and building mobile-first, we ensure your app looks great and functions smoothly on any device. Plus, when your app is easy to use, your users stick around longer and convert more often.
API & backend development
We build APIs (REST, GraphQL) and server-side systems that support everything your app needs to run smoothly. Moreover, our backend architecture is designed to scale easily, so your app stays strong even as your business grows.
Integration
No one wants to copy and paste data between systems all day. So we make sure your app talks smoothly with the tools you already use — Shopify, payments, shipping, internal software, you name it. Everything connects, updates automatically, and just works in sync.
Maintenance & support
We don’t disappear after launch. Bugs? We’ll squash them. New features? Let’s plan them. Something’s acting weird? We’re on it. Mageplaza stays in the loop with your team, so your app keeps improving as your store evolves.

Our software development process
Step 1
Discovery
We kick things off with a conversation — no tech talk, just understanding what’s not working for you and what you'd love to improve. Once we’re clear on the “why,” we map out what your app needs to do and what success looks like.
Step 2
Prototyping
Before diving into code, we sketch things out. Think wireframes, clickable mockups — something visual to help you see how the app will work. You can give feedback early, and we can tweak things before any development begins.
Step 3
Development
Now it gets real. Our team builds the app based on the approved prototype, piece by piece. We use solid, scalable code and Shopify-friendly tools to make sure everything runs smoothly — both now and later.
Step 4
Testing
We perform rigorous testing, achieving a 99% bug-free rate with manual and automated QA processes for functionality, performance, and security.
Step 5
Launch & training
Once everything’s good to go, we roll out the app to your store. If your team needs help learning the ropes, we’re right there with training, docs, and support. We want you to feel confident using it — not guessing.
