Expo vs Bare React Native — Which to Choose?
Direct answer
For most new apps in 2026, I recommend starting with Expo — modern Expo with development builds and config plugins removes almost every old reason to go bare, while giving you over-the-air updates, easier builds, and faster iteration. Go bare React Native only when you need a native capability Expo genuinely can't support, or you're integrating into an existing native app. The framework choice doesn't change the project budget much; most apps land in the $20K–$120K range based on features, not on Expo vs bare. The costlier mistake is ejecting from Expo prematurely because of an outdated assumption.

Why the old debate is mostly settled
For years, 'Expo vs bare' meant 'convenience vs capability' — Expo was easier but couldn't use custom native modules. That tradeoff is largely gone. Modern Expo supports development builds, which let you add any native library or custom native code while keeping Expo's tooling. Config plugins handle native configuration that used to force an eject. So today the honest default is Expo, because you get its benefits — cloud builds, over-the-air updates, a smoother upgrade path — without giving up native access.
Bare React Native still exists and still matters, but it's now the specialized choice, not the serious-developer default it was once seen as. Choosing bare should be a deliberate decision driven by a real constraint, not a reflex or a belief that Expo is only for prototypes.
When bare React Native still wins
There are legitimate reasons to go bare. If you're embedding React Native into an existing native iOS/Android app (the brownfield case), bare gives you the control you need. If you depend on a native SDK that isn't compatible with Expo's build system, or you need deep custom native code that fights the config-plugin model, bare removes the friction. Some teams with strong existing native expertise and established native build pipelines also prefer bare because it fits how they already work.
The key is that these are specific, nameable reasons. If you can't point to a concrete native requirement Expo can't meet, you probably don't have a reason to go bare — and you'd be taking on more build and maintenance work for no benefit.
What actually drives the budget
Neither Expo nor bare meaningfully sets your project cost — features do. The $20K–$120K range is driven by number of screens, backend complexity, real-time features, payments, offline support, and any AI or hardware integration. A simple app (a few screens, basic backend, standard auth) sits at the low end regardless of framework. A standard app (10–20 screens, real-time, payments, push) is mid-range. A complex app (heavy offline sync, custom native modules, deep integrations) reaches the top.
Where the framework does affect cost is indirectly. Expo tends to lower ongoing costs through easier builds, simpler CI, and over-the-air updates that let you ship fixes without an app-store review cycle. Bare can add maintenance overhead because you own more of the native build configuration. Over a multi-year app, that difference adds up more than the initial choice suggests.
Hidden costs, and how to decide safely
The biggest hidden cost is a premature eject. Teams sometimes leave Expo early over a requirement that a development build or config plugin would have handled, then inherit all of bare's maintenance burden permanently. Ejecting is easy to do and hard to undo. The opposite risk is smaller but real: choosing Expo while ignoring a genuine native constraint, then hitting a wall mid-project.
To decide safely, list your app's native requirements before you pick — cameras, Bluetooth, background tasks, specific SDKs — and check each against Expo's current support, not a two-year-old blog post. Start with Expo and a development build; you keep native access and can still eject later if a true blocker appears, which for most apps never comes. If someone quotes you far more 'because it's bare', ask what native requirement justifies it; often there isn't one.
People also ask
Can Expo apps use custom native code now?
Yes. With development builds you can add any native library or write custom native modules while keeping Expo's tooling and workflow. This is the single biggest change that makes Expo the sensible default today — the old limitation that Expo couldn't touch native code no longer applies. You only lose that convenience if you fully eject to bare.
Is it hard to switch from Expo to bare React Native later?
Switching from Expo to bare is straightforward and well-documented — you run a prebuild and gain full native project access. The hard part is that it's a one-way door in practice: once bare, you own all the native build config and lose Expo's managed conveniences. That's why I recommend starting with Expo and only ejecting if a concrete blocker appears.
Does Expo slow down app performance?
No meaningful runtime penalty for typical apps. Expo apps run on the same React Native engine and can use Hermes and the new architecture like bare apps. Performance is driven by how you write the app — list handling, re-renders, image loading — not by whether you used Expo. The old belief that Expo is inherently slower doesn't hold for modern Expo.
