React Native CLI vs Expo: When Should You Migrate?
Decision factors for brownfield apps: native modules, build pipelines, team skills, release cadence and risk.
Teams often ask whether to migrate a bare React Native CLI app to Expo. The answer depends on native code, release process, and how much build infrastructure you want to own.
When Expo is a strong fit
- Your native surface area is small or well-supported by Expo modules.
- You want EAS Build and streamlined credentials management.
- Your team benefits from consistent developer tooling and faster onboarding.
- You can adopt Expo incrementally (e.g. Expo modules in a bare app) before a full workflow change.
When to stay bare (or delay migration)
- Heavy custom native code or uncommon SDK integrations without Expo equivalents.
- Complex white-label or multi-app build matrices that do not map cleanly to EAS profiles.
- Regulatory or client constraints requiring full control of native projects.
Brownfield migration pattern
A pragmatic path is: audit native modules → prove a branch with Expo modules or prebuild → run parallel CI builds → migrate one platform at a time → cut over store pipelines only when release parity is demonstrated.
