6 Best Shopify App Development Companies for US Brands in 2026

For US brands that want to own the code behind their store's most important features, the best Shopify app development company in 2026 is Netalico, a Shopify Plus Premier Partner founded in 2011 whose in-house team across the Americas handles custom Shopify app development alongside the store itself. The other five Shopify app development companies on this list are offshore teams with lower hourly rates, each strong in a different kind of app.

The question brands ask has changed this year. October's App Store incidents took popular search and upsell apps offline overnight, and Shopify now requires public apps to move to expiring access tokens by January 1, 2027. The decision is no longer only which app to install: it's which features to keep renting and which to build and own.

How We Ranked These Shopify App Development Companies

We scored each company on five weighted criteria, using its own site, its Shopify App Store listings and its published case studies:

• Shopify platform depth (30%): hands-on work with Shopify Functions, checkout UI extensions, the GraphQL Admin API and App Bridge, not general web development.

• Code ownership and handover (25%): whether the brand gets the source code, documentation and hosting accounts at the end.

• Security and maintenance (20%): how the team handles access tokens, API version updates and Shopify's 2027 deadlines.

• US fit (15%): working-hour overlap, US offices or hubs, and experience with US mid-market brands.

• Price transparency (10%): published rates, ranges or a free scoping step.

Shopify App Development Companies at a Glance

The 6 Best Shopify App Development Companies for US Brands

1. Netalico

Netalico builds custom Shopify apps, theme features and Shopify Functions for stores it also designs, migrates and supports, so its developers already know each store's data, theme and checkout. Every project starts with a rent-or-own call: apps that hold years of data, like reviews and email, stay, while purchase-path features such as search, filtering, product options and pricing rules get rebuilt. When a search app went down overnight in October 2026 and blanked a client's collection pages, the team began rebuilding search and filters natively as a backup.

Apps that need a server run on Cloudflare, the same network Shopify's storefronts use, and the client receives the full source code and the accounts it runs on. For brands unsure where to start, a Shopify app risk audit ranks installed apps by how much the store depends on each one and what breaks when it fails.

• Notable builds: a custom app that syncs Spanish product content from Salsify into Shopify for Shop QEP, and native volume pricing through Shopify Functions for SpeedTech Lights, with no pricing app and no added JavaScript.

• Clients: Big Green Egg, Shop QEP and SpeedTech Lights.

• Process: scope with a written fallback, build on a development store, launch with the old app still installed until the new build is proven, then hand over code and documentation.

• Pricing: projects from $25,000 to $250,000+, and retainers from $2,700 to $10,000 a month for ongoing app maintenance.

• Best for: US brands doing $2M to $50M GMV that want one team for the store and its custom code.

2. DigitalSuits

DigitalSuits, a Shopify Plus partner founded in 2016 with offices in Miami and New York, builds both single-store custom apps and public apps for the App Store. Its app work covers OAuth, embedded app architecture, billing, multi-store support and preparation for Shopify's app review, which matters if a brand plans to sell its tool to other merchants.

Its public app work includes ReturnGo, a returns management app, and SecuLinks, a link redirection app. The agency also runs a separate practice for app extensions, focused on keeping them compatible as Shopify updates its APIs.

• Team: 60+ staff and 200+ delivered projects.

• Specialty: public App Store apps and app extensions.

• Pricing: quote-based, with retainers from $2,700 for 60+ hours a month.

• Best for: brands that want to turn an internal tool into a public app.

3. CodingKart

CodingKart has built on Shopify since 2013 and works from New York with a development team in Indore, India. Its app practice centers on subscription brands: delivery partner and 3PL integrations, subscription event automation, admin tools built with App Bridge, and data sync apps that work with Recharge and Appstle.

One example is a custom app for ChiDog that picks up Shopify subscription orders through webhooks, attaches each pet's profile data and sends the order to the brand's delivery partner. CodingKart publishes its timelines: 2 to 4 weeks for a simple app, 4 to 8 weeks for a mid-size app and 3 to 5 months for a complex one.

• Stack: Admin, Storefront and Webhooks APIs, App Bridge, Shopify Functions and checkout UI extensions.

• Specialty: subscription and fulfillment apps.

• Pricing: quoted after a free scope review, with no discovery fee.

• Best for: subscription brands running Recharge or Appstle.

4. BSS Commerce

BSS Commerce, part of BSS Group since 2012 and based in Hanoi, publishes and maintains its own apps on the Shopify App Store. Its BSS B2B Wholesale Solution app, on the App Store since September 2020, handles custom pricing, volume discounts, registration forms, minimum orders and net payment terms.

That product experience carries into client work. BSS builds new apps on demand, adds features to existing apps and connects third-party tools, and its FAQ puts typical custom Shopify development at 8 to 12 weeks.

• Specialty: App Store products plus custom builds.

• Credentials: Shopify Partner with 580+ projects across Shopify, Plus and Magento.

• Pricing: $25 to $49 an hour, with projects from $5,000.

• Best for: brands that want developers who maintain live apps used by other merchants.

5. Magneto IT Solutions

Magneto IT Solutions was founded in 2010 in Ahmedabad and has US offices in New York and San Francisco. It is a Shopify Plus partner whose app work leans on Plus-only tools: Shopify Functions for custom discounts, delivery rules, payment logic and validation, and checkout extensions.

That makes Magneto a fit for stores whose app needs sit inside checkout rather than the admin. It also builds custom apps that automate workflows and connect Shopify to business systems, and it sells developer time in hourly packages that start at 60 hours.

• Specialty: Functions and checkout extensions.

• Also builds: Hydrogen and Next.js storefronts, and migrations from Magento, WooCommerce and BigCommerce.

• Pricing: $25 to $49 an hour, in packages from 60 hours.

• Best for: Plus stores with custom pricing, shipping or payment rules.

6. WebContrive

WebContrive, founded in 2012 in Surat, India, builds custom public and private Shopify apps. Its integration work is the main draw, with documented connections to ERPs such as NetSuite and SAP, CRMs such as Salesforce and HubSpot, and PIM, 3PL and loyalty platforms.

Every engagement starts with a written functional specification before a price is agreed, which keeps scope creep out of integration projects. Its own cost guide runs from about $5,000 for a basic app to $200,000+ for enterprise builds.

• Specialty: ERP and CRM integration apps.

• Also offers: white-label development for other agencies.

• Pricing: $25 to $49 an hour, with projects from $1,000.

• Best for: brands connecting Shopify to NetSuite or SAP on a tighter budget.

How Much Does Shopify App Development Cost?

Published prices put a basic custom app at around $5,000 and an enterprise integration at $200,000 or more. Offshore teams on this list bill $25 to $49 an hour, while US-based teams cost more per hour but share your working day.

Timelines are CodingKart's published ranges. Ongoing cost matters as much as the build: Shopify releases a new API version every quarter, and a custom app needs a named owner to update it, monitor it and fix it when a webhook changes. Budget for a retainer from day one.

Custom App or Public App: Which Do You Need?

A custom app is built for one store, isn't listed on the App Store and can't be delisted by anyone else. A public app is listed on the App Store, installed by many merchants and has to pass Shopify's review.

• Build a custom app for features on the purchase path, integrations with your own systems and logic that gives you an edge over competitors.

• Keep renting an App Store app for reviews, email and SMS, fraud screening and other tools that hold years of data or vendor expertise.

• Build a public app only if you plan to sell the tool to other merchants, which means App Store review, billing and support for other people's stores.

Custom Shopify Functions and checkout extensions require Shopify Plus. Most other custom apps and theme features run on any plan.

Shopify Rules Every App Developer Must Follow in 2026

Two platform rules shape every Shopify app built this year:

• GraphQL only for new public apps: apps submitted to the App Store since April 1, 2025 must use the GraphQL Admin API, and the REST Admin API has been legacy since October 1, 2024.

• Expiring tokens by January 1, 2027: public apps still using non-expiring offline access tokens will be delisted and blocked from new installs, and from April 1, 2027 those tokens return errors. Custom apps aren't affected.

Ask any company on this list how its code handles both before you sign.

How to Choose a Shopify App Development Company

Ask every shortlisted company these six questions:

1. Who owns the code, the hosting account and the app's API credentials after launch?

2. Which Shopify APIs and extensions will the app use, and does any of it need Shopify Plus?

3. How will you test it: on a development store, with the old app still installed?

4. What's your plan for Shopify's quarterly API versions and the 2027 token deadline?

5. Who answers when the app breaks during Black Friday, and in which time zone?

6. Can you show a live app or a case study with a similar integration?

Walk away from any team that can't name who maintains the app after launch.

Shopify App Development Companies: FAQs

What does a Shopify app development company do?

It builds software that extends Shopify: admin tools, ERP or 3PL integrations, Shopify Functions for pricing and shipping rules, and checkout or theme extensions. Some also build public apps for the App Store.

How much does it cost to build a Shopify app?

Published ranges run from about $5,000 for a basic custom app to $200,000+ for enterprise integrations. Offshore teams charge $25 to $49 an hour, while US teams cost more but overlap your working hours.

How long does Shopify app development take?

A simple custom app takes 2 to 4 weeks, a mid-size app 4 to 8 weeks and a complex integration 3 to 5 months. Features like a wishlist or native filtering take weeks, not months.

Do I need Shopify Plus to build a custom app?

Not for most custom apps and theme features. You do need Plus for custom Shopify Functions and checkout extensions, which run inside Shopify's checkout and pricing logic.

Should I build a custom app or use an App Store app?

Build features on your purchase path and integrations unique to your business. Keep App Store apps for reviews, email, SMS and fraud tools that hold years of data or vendor expertise.

Who maintains a custom Shopify app after launch?

The agency on a support retainer, or your own developers. Either way, you should own the source code, hosting account and documentation so you can switch teams without a rebuild.

Which is the best Shopify app development company for US brands?

Netalico ranks first for US mid-market brands because the team that builds the store also builds and maintains its custom apps. DigitalSuits suits brands launching a public app, and CodingKart suits subscription brands.
