Adopt React Native in simple and incremental way
We help large organizations adopt React Native the right way—incrementally, safely, and without business disruption. Whether you're extending native apps or planning a full transition, we build the technical foundation and processes needed to succeed at scale.
What makes React Native adoption hard for enterprise teams
Adopting React Native in a large organization isn't just a tech decision—it’s a process challenge. Without a clear migration path, teams often struggle to integrate React Native effectively—or abandon adoption altogether.
No clear migration path
Deciding what to migrate, when, and how is often unclear. Without a solid plan—screen selection, KPIs, validation steps—teams lose momentum before they start.

Code sharing often fails
Even with React Native, teams may keep building features separately. Without clear ownership and structure, cross-platform reuse breaks down before it delivers real value.

Lack of internal buy-in
Getting native engineers onboard takes time. Without training, context, and proper technical setup, teams struggle to build confidence around new tooling and workflows.

AutoZone migrated to React Native while releasing every two weeks
Callstack worked closely with AutoZone to plan and execute a gradual migration from native to React Native. Over 18 months, the app launched a full redesign, added new functionality like push notifications and mobile payments, and improved its Google Play rating from 4.2 to 4.6—all while doubling its user base.

Migrate to React Native safely without disrupting your native app
React Native Brownfield was designed to solve one of the hardest parts of React Native adoption at scale: enabling gradual, type-safe migration without affecting existing Android and iOS development. It allows teams to introduce React Native incrementally without changing how native teams operate.
- Zero overhead for your existing Android and iOS teams
- Type-safe boundaries between native and React Native
- Transition gradually toward a fully cross-platform architecture

FAQs
Migrating to React Native raises critical questions about technical risk, team readiness, and delivery stability. Here’s how we approach the most common challenges teams face when planning and executing a safe transition.
We use a brownfield approach—introducing React Native as a module inside your app—so you can transition incrementally, without risking stability or breaking workflows.
We build a production-grade POC inside your app to validate integration points, UX performance, navigation, and backend connectivity—allowing early, low-risk validation.
We assess your app architecture, user flows, and business priorities to recommend low-risk, high-impact entry points for React Native adoption.
Yes. We design migration plans that integrate with your existing CI/CD pipelines and development schedules—minimizing disruption to releases.
We focus on critical areas like startup time, navigation smoothness, and animation performance—applying platform-specific optimizations where needed.
We deliver technical trainings, workflow adjustments, and ongoing architectural guidance to ensure your teams can scale React Native confidently after initial adoption.
Yes. Our approach is designed for gradual migration—allowing you to add new screens or features in React Native without rewriting the entire app at once.
