Most of the answers you hear sound familiar:
These statements are not completely wrong, but they also do not explain what actually separates the two.
A few months ago, while helping a junior developer set up their first mobile app, they asked a simple but important question:
“Which one should I choose and why does this choice even matter?”
That question stayed with me, because most developers make this decision based on advice they hear, not on real understanding. So let’s dive in this. Not a comparison table nor a pros and cons checklist. Just the real difference about how each option works? What it hides? And What it exposes.
Expo and React CLI (Command Line Interface) are not two different frameworks. Both use:
Your components, hooks, state, styles and logic stays the same is both cases. The real difference is how much of the native side you see and control.
Think of it like: React Native acts as a bridge between JavaScript and native mobile code. Now imagine two ways of working with that bridge:
This is the real split between Expo and React Native CLI.
Expo is a layer built on top of React Native.
It provides:
When you choose Expo, you are essentially saying:
“I want to focus on building features instead of setting up the native environment first.”
That is what Expo is designed to support.
It’s also important to note that using Expo does not mean you avoid native code. With Expo Modules and Config Plugins developers can still write and use native code when needed, even inside an Expo project.
Out of the box, Expo gives you access to things like:
These features are available through Expo’s APIs, so you don’t need to set them up manually in the native project at the start.
You also don’t always need to work directly inside tools like Xcode or Android Studio in the early stages of development.
However, many developers still use those tools with Expo when they need deeper debugging, custom native work or when building the final production app.
React Native CLI is the raw, direct setup. It gives you:
When you choose the CLI, you are saying:
“I want full control, even if that means more work.”
You see everything:
If I have to state the difference in one line, I would say:
That single idea explains most of the difference in day-to-day development.
However, using Expo does not mean you are limited. You can still write native code and implement any native feature when needed using things like Expo Modules or by extending the native projects.
With Expo: When you use Expo, you work within a predefined setup.
If Expo already supports a native API, you can use it immediately without doing extra native setup. This makes it very quick to start building features. Because of this approach, Expo tends to be:
In the past, if you needed something that Expo did not support, you had to “eject.”
Ejecting meant converting your Expo project into a regular React Native project with full native folders (ios and android). After that, you would work directly with tools like Xcode and Android Studio to add native code or libraries.
However, the term “eject” is now deprecated.
Today, Expo uses a different approach called Prebuild. With the npx expo prebuild command, Expo can automatically generate the native ios and android projects based on your app configuration and the libraries you install.
This means:
Because of this change, you are no longer locked into only what Expo supports. You can extend the app with native code whenever it is needed while still using Expo’s tooling.
Now, on the other side of this same coin sits the CLI. Everything we just covered about Expo, the predefined setup, the managed APIs, the guardrails, the CLI takes the opposite approach.
With React Native CLI: There are no defined boundaries. You can use:
But this also means you are responsible for everything that comes with that freedom, including:
You get more control, but that control comes with more responsibility.
Let’s clear this up. Expo apps are not slower by default. Performance depends on things like:
These factors matter far more than whether you can chose Expo or the CLI.
Poor architecture will feel slow in both cases. Good architecture will feel fast in both cases.
Instead of following opinions, it helps to ask yourself a few practical questions.
Today, the general recommendation from the React Native Team is to start with Expo by default.
Choose Expo if:
Expo is now the default starting point for many new React Native projects because it handles a lot of the tooling and setup for you, while still allowing native code when needed.
Choose React Native CLI if:
Both options are fully professional and used in real production apps. The difference is not about skill level, it is about the use case. For the majority of projects, Expo covers everything you need, and that is exactly why the React Native team recommends it as the default starting point.
Many developers treat Expo vs CLI as a permanent choice; it is not…
A common and healthy approach is:
That is not switching tools. It is letting your app grow naturally
And thanks to Prebuild and Config Plugins, you rarely even need to leave the Expo ecosystem. You can add custom native code, use any React Native library, and generate native projects whenever needed, all without abandoning Expo's tooling.
Expo is not created to replace React Native CLI. It exists to remove friction until you are ready to handle more complexity yourself.
Once you understand this, the question changes. You stop asking:
“Which one is better?”
and start asking:
“What problem am I solving right now?”
That shift is what separates following tutorials from thinking like a developer.
If this breakdown helped you see React Native, Expo and the CLI more clearly, the next step is learning how to work with these ideas in real projects.
That’s exactly what our React Native course is built for. It starts from the basics, explains how React Native works behind the scenes and shows you how to make practical decisions as your apps grow from choosing Expo or CLI to knowing when and why to eject.
If you want a clear, structured path to learning React Native without guessing or jumping between tutorials, this course is a solid place to begin.
