React Native’s capability markers are different from other frameworks, because its distinctive strengths are integrating with existing native applications and surviving a demanding upgrade cycle. A team that can build a greenfield app may still be unable to do either. This page covers what to verify, with particular attention to the architecture transition that has recently made a large amount of accumulated experience partially obsolete.
New Architecture Experience Is Now the Baseline
The framework completed a multi-year architectural transition, and teams differ sharply in whether they have worked on the current architecture or only on what preceded it.
Ask Directly About the New Architecture
JSI, Fabric, and TurboModules replaced the old JavaScript bridge, and as of version 0.82 there is no legacy fallback available. A team unfamiliar with this is describing outdated experience.
Ask Whether They Have Migrated an App
Migrating an existing application to the New Architecture is materially harder than starting on it. Teams who have done it have encountered the real problems.
Check Their Position on Library Compatibility
Not every third-party library supports the current architecture equally. Teams who assess library readiness before committing have been through this.
Listen for Outdated Performance Claims
A team still describing bridge overhead as a current limitation has not worked on a recent project. Our cross-platform app development assessments use current behaviour.
Brownfield Integration Capability
Adding React Native to an existing native application is the framework’s distinctive capability and the one fewest agencies have genuinely done.
Ask Whether They Have Shipped Brownfield
Integrating React Native into a working native app, for specific features, without rebuilding the product. This is a meaningfully different skill from greenfield delivery.
Check They Can Work in Native Code
Brownfield work requires reading and writing Swift, Kotlin, or Objective-C alongside JavaScript. Teams without that capability cannot do it.
Ask How They Handle Navigation Boundaries
Moving between native and React Native screens is where brownfield integrations get awkward. Specific answers here indicate real experience.
Why This Matters Commercially
It means you can adopt incrementally rather than betting a product. Our mobile app development work uses this to de-risk migration.
Native Module and Platform Work
React Native covers common needs through libraries and requires native work beyond them. Teams differ in whether they can cross that line.
Ask About Native Modules They Have Written
Teams who have written TurboModules or native components have worked at the boundary. Teams who have only consumed libraries have not.
Check Their Library Evaluation Practice
The ecosystem contains abandoned and poorly maintained packages. Strong teams check maintenance status before adopting and are willing to fork or replace.
Ask About Platform-Specific Handling
React Native uses native components, so interfaces differ between platforms by default. Teams should describe how they handle that deliberately rather than claiming it does not happen.
Confirm Both Platforms Are Tested Properly
Expect meaningful but not complete code reuse, with platform-specific work remaining. Our software development estimates account for that split.
Upgrade and Maintenance Practice
React Native has historically been demanding to upgrade, and a team’s practice here determines whether your codebase stays maintainable or becomes stranded.
Ask How They Handle Version Upgrades
A defined practice for tracking releases and applying upgrades, rather than upgrading only when forced. This protects you from an unupgradeable codebase.
Check Dependency Discipline
The JavaScript ecosystem has substantial dependency churn. Teams with a policy on adding dependencies produce more maintainable applications.
Ask About Their Build and Release Pipeline
Automated builds, environment configuration, and store submission handled routinely. Our DevOps services work covers this layer.
Confirm They Can Support After Handover
Whether they offer ongoing maintenance and what that covers. Upgrade work is continuous rather than occasional in this framework.

FAQs
How do I evaluate a React Native development company?
Ask whether they have worked on the New Architecture and migrated an app to it, whether they have shipped brownfield integrations, what native modules they have written, and what their version upgrade practice is.
What is the New Architecture and why does it matter?
JSI, Fabric, and TurboModules replaced React Native’s JavaScript bridge, and as of version 0.82 it is the only architecture with no legacy fallback. Teams unfamiliar with it are describing experience that is now partially outdated.
What is brownfield React Native and why ask about it?
Adding React Native to an existing native application for specific features rather than rebuilding. It is the framework’s distinctive capability, requires native code skills alongside JavaScript, and fewest agencies have genuinely done it.
Does a React Native team need native platform skills?
Yes, for anything beyond straightforward applications. Native modules, brownfield integration, and platform-specific handling all require reading and writing Swift, Kotlin, or Objective-C. Teams without that capability hit a ceiling quickly.
How much code is shared across platforms in React Native?
Meaningful but not complete. Platform-specific work remains, particularly for interface differences, since React Native renders using native components which behave differently on each platform by design.
Why does upgrade practice matter so much?
Because React Native has historically been demanding to upgrade, and a team without a defined practice leaves you with a codebase that becomes progressively harder to move forward until it is effectively stranded.
