Shopify App Developers
Shopify Full-Stack Development Agency
We’ve specialised in Shopify backend development since 2012, and have a team of experienced developers who create bespoke functionality and apps for the world’s best ecommerce brands.
Public Shopify Apps And Custom Shopify Apps
What is the difference between a public Shopify app and a custom Shopify app?
A public app is one that’s listed in the Shopify App Store and can be installed by any business with a store on the Shopify platform. A custom app is not listed in the app store and is only installed on a single merchant’s store - the merchant that has created or commissioned the creation of the custom app.
1. Public Shopify Apps
Public apps provide additional functionality to extend Shopify’s native features, and are available to install on any Shopify site from the App Store. When developed, the apps are submitted to Shopify for verification before being made publicly available. These apps can be free, they can demand a one-off payment, or they can incur a monthly or annual cost. Sometimes an app will have a free plan, and often tiered or premium versions in which merchants pay for additional features and benefits.
One thing to consider with public apps is that because they are designed for mass use, they are never completely tailored to an individual store or one business’ highly specific need.
2. Custom Shopify Apps
Custom apps are a way to add features, functions, or improve usability on a store in a way that no publicly available apps are able to. Custom apps are built specifically for an individual merchant and can perform many functions, such as adding extra features to your admin panel or accessing your store data directly using Shopify’s APIs.
It can be hugely beneficial to go down the route of bespoke development for custom apps if the use is clearly defined.
Why choose custom Shopify apps?
Custom apps are tailored to solve an issue or enhance functionality specifically on your site as opposed to public Shopify apps, which are built to work on many stores with a ‘one size fits all’ approach.
You own the app so have complete control to make changes or add features as you require.
Custom apps can be used to add features to your Shopify admin, access your store’s data directly via Shopify’s subscription API, or extend your online store to other platforms using the Storefront API.
We're Expert Shopify App Developers
If you need a new Shopify store, require specific functionality via an app, or would benefit from custom integrations with your store, our Shopify developers are here to help. Shopify provides a robust and feature-rich ecommerce platform that suits most enterprises. But when you need something specific that's unique to your business, we can build it.
Eastside Co is at the forefront of Shopify app development. If there’s something you need your website to do outside the parameters of the standard Shopify platform, then talk to us about your needs for bespoke functionality. We also build public apps that can be listed in the Shopify App Store and installed by merchants around the world.
We’re also experts in payment gateway integrations and developed the public Shopify app for TrueLayer, allowing UK and EU merchants to add open banking payments to their checkout. As a result, they can quickly benefit from a faster, more secure payment option at a fraction of the cost of cards or PayPal.

Ecommerce testing covers every component of the site’s functionality and integrations. Our QA team helps prevent errors, adds value to the end product, and helps guarantee that your integrations and apps will run flawlessly on a variety of desktop and mobile devices.
Case Study: Pristine Classical
This is one of our favourite custom apps we’ve developed outside of Shopify. The requirement for Pristine Classical was to create an online streaming service specifically for remastered classical music. Immaculate sound quality was of the highest importance.
Pristine asked Eastside Co to develop an app which allowed for the perfect digital listening experience. We used cutting edge web audio technology and content streaming architecture to do just that, creating one of the first apps to support FLAC (Free Lossless Audio Codec), a high quality audio format.
Pristine now has over 12,000 perfectly remastered classical pieces, available to stream in the best audio quality via the app.
Case Study: Clicksit
Clicksit provides an out-of-the-box, cross-carrier, ecommerce returns solution for retailers of all sizes.
Recognising the potential to reach millions of online stores through the Shopify ecosystem, Clicksit approached Eastside Co to create a public app that Shopify merchants can install directly into their own store. The aim was to capture the existing functionality and superb service, but to make it available through an easy-to-install, intuitive public app in the Shopify store.
The end result? A five-star rated app, enabling millions of online store owners to improve their returns experience, giving their customers the confidence to buy, and keep coming back.

What Our Shopify App Clients Are Saying About Our Work
I really like Klarna On-Site Messaging, especially on the product page. It converts our customers over to the checkout very naturally. And, because it doesn’t cost anything to buy with Klarna, it’s a very nice offering. We’re really trying to help our customers make their purchases.

Shopify App Development FAQs
Some further information about our Shopify app development services.
-
What are the timeframes for creating an app or custom functionality?
If you choose Eastside Co for your project, your dedicated team will provide a timeframe for delivery including key milestones as part of the roadmap. Every app development project is different with many variables, and can involve different levels of complexity and requirements. Each project’s timeframe is unique to the project itself. Once we have agreed the delivery dates, we communicate progress transparently and regularly throughout the project via regular calls with your dedicated team. Contact us for a discussion. -
What language do you use to develop custom Shopify apps?
For Shopify app development we use PHP and the Laravel framework to create the core functionality. That includes custom apps that we are building for our clients, as well as the public apps we make available for installation from the Shopify App Store. We also use React for custom app development to provide components to extend the administration area User Interface (UI) and the UI of the app itself. -
How much does it cost to build Shopify custom apps or bespoke functionality?
This very much depends on the project - our consultative process means that we discuss the needs of each client in order to determine the best approach. Our business development team will scope the project with you to understand your requirements, and agree on the investment required. Get in touch with them for an initial chat. -
What are the benefits of working with Eastside Co to develop our custom app functionality?
We have a really experienced team of app developers here at ESC who have vast experience with the Shopify platform and the development of both public and custom apps. We’ve been working with the platform for over a decade. In addition, if the app has a user interface our expert UX and UI designers work closely with the development team to make sure that the app works brilliantly and is intuitive for the user. -
Do you have examples of some of the public or custom apps you’ve created?
Yes - we’ve developed public Shopify apps for the likes of Klarna, what3words, Voyado and Truelayer, and have created custom apps for other clients including Hearts of London (a jewellery store that needed a bespoke diamond selector) and Lust London (a wallpaper brand that needed custom functionality for working out how many rolls of paper are needed for specific sizes of walls). Our case study page goes into several of these in more detail. -
I have an idea for an app that I’d like to make available in the Shopify App Store - can you help?
Yes. Our development team can build apps for you to list and sell in the Shopify store under your name. If your business provides a service that you want to offer to Shopify users, we can help you create an app to integrate your solution into merchants’ stores. If you want to convert an online service into a Shopify integration, but don’t have the resources to build your own public app, we can build it to your specification, under your own name.
