React Native, Flutter, and Kotlin Multiplatform: comparison

ParameterReact NativeFlutterKotlin Multiplatform
PerformanceGood for most business tasks; heavy UI requires native embedshigh, proprietary UI rendering engineclose to native: shared business logic, native UI

Read the table row by row under "Enterprise-fit" and "Offline and security": if the app is a showcase or MVP, RN and Flutter win; if it is a work tool tied to enterprise systems and offline operation, Kotlin Multiplatform with shared business logic and native UI is stronger.

When to choose what for each scenario

  1. 01

    Fast, vivid consumer interface

    Need a beautiful custom UI on iOS and Android from one codebase? Choose Flutter.

  2. 02

    MVP and fast team hiring

    Need to validate a hypothesis cheaply in a few months and hire developers easily? Choose React Native.

  3. 03

    Enterprise, integration, and offline

    If the app works with 1C, ERP or PIM, must run offline and meet security requirements, choose Kotlin Multiplatform with native UI (native-first).

Map out your integration landscape

A mobile app as a front end for 1C, ERP, PIM and ESB

  1. For mid-sized and large businesses, a mobile app rarely exists on its own.

  2. Most often, it is an employee work tool: warehouse, logistics, sales rep, or on-site receiving.

  3. Such an app is a front end to the enterprise landscape, and the technology choice is driven less by UI beauty than by how it fits into 1C, ERP, PIM, and the integration bus (ESB).

  4. Key requirements for such a front end are offline synchronization so work does not stop without a network, role-based access and device management, and predictable behavior at peak load.

  5. Here, shared business code (Kotlin Multiplatform) provides an advantage: synchronization and access rules are written once and reused across all platforms, while the native UI remains responsive.

  6. This angle - the app as an integration front end, not a showcase - is usually not the focus of specialized mobile studios. KT.Team approaches mobile development from enterprise systems integration practice: the app is designed together with the backend and data flows, not layered on top of an existing one.

KT.Team experience: mobile front end for enterprise processes

Need not to choose a framework, but to get an app for integration

If the goal is less to choose a technology and more to get a mobile app that fits into 1C, ERP or PIM and works offline, discuss the project with the KT.Team: order mobile app development. When the scenario is web-first and a lightweight solution without app store installation is enough, a progressive web app may be cheaper. PWA - a progressive web app instead of native cross-platform.
