Top 6 software development companies working with React Native

For years, the market debated whether cross-platform solutions were viable for enterprise-grade applications. That debate is over. When giants like Microsoft, Shopify, and Meta rely on React Native for their core products, the technology has proven its stability. The challenge now isn’t the technology itself; it is finding the right partner to execute it.

The market is crowded with agencies claiming expertise. Most are generalists who dabbled in JavaScript and added React Native to their portfolio to capture leads. You do not want generalists. You want specialists who understand the bridge between native code and JavaScript, who contribute to the open-source ecosystem, and who can solve architectural bottlenecks before they threaten your launch date.

Below is a list of software development companies that define the current standard for React Native development.

The selection process: what you need to know

Before you review the list, understand how to evaluate these vendors. A high hourly rate or a slick website is not a guarantee of quality.

Look at open source contributions

React Native is open-source. The best agencies don’t just use the library; they build it. If a company maintains key libraries (like navigation, testing, or animation tools) used by the rest of the world, they possess a depth of knowledge that standard agencies cannot match. They can debug issues at the framework level.

Assess technical communication

Your partner must translate complex technical constraints into business decisions. If they cannot explain why a specific animation will impact performance on low-end Android devices in plain English, they will struggle to manage your budget effectively.

Check for "brownfield" experience

If you have an existing native app and want to integrate React Native screens gradually, this is called "Brownfield" development. It is significantly harder than building from scratch. Ask potential partners about their experience with this specific architecture.

1. Curiosum

Location: Poland

Best for: Scalable MVPs and the Elixir + React Native technology stack.

This agency secures a unique competitive advantage by working with a specific full-stack environment: React Native for the user interface and Elixir’s Phoenix Framework for server-side operations. This is a strategic business choice. Elixir is known for handling massive concurrency and real-time communication with high reliability.

If you are building a platform that requires real-time features - such as a messaging app, a betting platform, or a complex fintech solution - Curiosum provides a backend infrastructure that will not crash under heavy load, paired with a React Native mobile experience. They are an ideal partner for startups and scale-ups that want to build an MVP that is technically capable of handling millions of users from day one without a complete rewrite.

2. Software Mansion

Location: Poland

Best for: Multimedia apps, complex animations, and heavy UI interactions.

Software Mansion engineers are the architects behind some of the most important libraries in the ecosystem, specifically react-native-reanimated and react-native-gesture-handler. If you have used a React Native app with smooth, 60fps animations, it likely relied on code written by this team.

They focus heavily on the "native" part of React Native. Their expertise lies in bridging the gap between JavaScript and native platform capabilities, particularly in multimedia. If your product involves video streaming, camera manipulation, or complex gesture-based navigation, Software Mansion has likely already written the underlying code to make it possible. They are less of a generalist agency and more of a specialized technical strike team.

3. Callstack

Location: Poland / Remote

Best for: Enterprise scaling, performance optimization, and difficult technical challenges.

Callstack is not just a development agency; they are effectively an extension of the React Native core team. They organize the React Native EU conference and maintain critical tools like the React Native Testing Library. Their position in the market is unique because they often handle the problems other agencies fail to solve.

If your application demands complex integrations, heavy performance optimization, or you are a large organization migrating from native to cross-platform, Callstack is the safe bet. They specialize in high-stakes environments where technical debt is not an option. They also offer "brownfield" integration services, helping companies like Shopify embed React Native into their massive existing applications.

4. Infinite Red

Location: USA

Best for: US-based consulting, code audits, and long-term partnerships.

Infinite Red is a household name in the React Native community, primarily known for the "Ignite" boilerplate, which is the standard starting point for thousands of apps worldwide. Being fully US-based, they offer a level of communication and time-zone alignment that creates a workflow for North American clients.

Their service model is premium. They don't just write code; they guide your entire engineering culture. They are excellent for code audits—coming into a project that is failing and providing a roadmap to fix it. Their team hosts the React Native Radio podcast and the Chain React conference, keeping them permanently plugged into the latest industry shifts. Choose them if you want a partner who acts as a technical co-founder.

5. Miquido

Location: Poland

Best for: Full-cycle product development and AI integration.

Miquido positions itself as a business partner first and a software house second. While they have deep technical expertise, their value proposition focuses on the entire product lifecycle—from market research and strategy to post-launch support and growth.

They have integrated Artificial Intelligence into their service offering more aggressively than many competitors. If your React Native application needs personalized recommendations, voice assistants, or computer vision features, Miquido has the in-house data science talent to support the mobile team. They are a strong choice for startups and scale-ups that need a "one-stop-shop" to take a concept from a whiteboard to a revenue-generating product.

6. Droids On Roids

Location: Poland

Best for: Transparency and high-quality visual apps.

Droids On Roids has built a reputation on radical transparency. They provide clients with detailed access to the development process, ensuring there are no black boxes regarding billing or progress. Their culture is heavily focused on long-term relationships rather than quick fixes.

They are particularly skilled at creating visually stunning applications. While some agencies focus purely on logic, Droids On Roids emphasizes the "feel" of the application. They are an excellent fit for consumer brands where the app creates the primary connection with the customer. Their open-source contributions and active blog demonstrate a team that takes pride in technical craftsmanship.
