Ecosystem-first Shopify App Development
What we do best
Welcome to our lab. This is where we build ecosystem-first Shopify apps, built on native UI, solving real-world problems, and always aligned with how commerce evolves. We develop on-demand for others: from custom merchant solutions, to SaaS companies entering the Shopify ecosystem, to secure, scalable payment integrations.
Custom App Development
Bring your unique workflows to life with tailored apps built just for your business. We create seamless, scalable solutions fully aligned with Shopify’s architecture.
Public App Development
Launch apps that solve real problems and scale in the Shopify App Store. From concept to approval, we handle the full lifecycle, code, UX, and compliance.
Payment Gateway Development
We help third-party payment providers integrate their solutions into Shopify, from building the technical integration to meeting Shopify’s requirements for a successful launch.
How we build ecosystem-first apps
All insights start at iggy.agency, where we work hands-on with leading Shopify merchants. From those real-world challenges, we identify patterns, turn them into app concepts, and build scalable solutions. This way we skip long market studies, move fast, and ship apps merchants truly want.
How we build and think about apps
A Shopify App Development Partner is a company or developer officially registered in the Shopify Partner Program with a focus on creating apps for the Shopify ecosystem. These apps can be either public (available through the Shopify App Store) or custom-built for individual merchants with specific needs.
Partners in this category follow Shopify’s technical standards, API guidelines, and app review processes to ensure quality, security, and platform compatibility. Becoming a registered partner demonstrates verified access to Shopify's developer tools, partner resources, and app publishing infrastructure.
This partnership role is essential to the broader Shopify ecosystem, allowing merchants to extend their store functionality with trusted, purpose-built app solutions.
On Shopify, apps are categorized as either Public or Custom, and the key difference lies in their audience and distribution.
Public apps are designed to serve a broad range of merchants. They are distributed through the Shopify App Store and must meet strict security, performance, and UX standards. These apps are subject to Shopify’s approval process and offer built-in features like app billing, discoverability, and automatic updates.
Custom apps, on the other hand, are built for a single Shopify store or a specific client use case. They are not listed on the App Store and do not require approval from Shopify, which allows for quicker deployment and complete flexibility. Custom apps are often used for highly specific workflows, private integrations, or when merchant data needs to remain strictly internal.
For us, ecosystem-first means building apps that are fully aligned with Shopify’s native features, roadmap, and best practices. Instead of reinventing the wheel, we extend what’s already there—keeping apps lightweight, scalable, and future-proof.
Yes. All our apps are designed using Shopify Polaris UI. This ensures a familiar, consistent experience for merchants, reduces the learning curve, and guarantees full alignment with Shopify’s interface standards.
Insights come directly from iggy.agency from requests, where we work hands-on with Shopify merchants. Real-world merchant challenges drive our roadmap, ensuring we solve actual problems instead of building features no one needs.
Once an app is built, rolled out and configured, we continuously listen to merchant feedback, analyze usage data, and release updates. This way, our apps evolve with merchants’ needs and Shopify’s ecosystem changes.
