An online React compiler lets you write, run, and test React code instantly in your browser—no installation or setup required. Just open Nottri.com, select React, and start coding. Whether you're a student, teacher, or developer, our platform provides a fast, accessible, and powerful way to practice, learn, and build projects from anywhere.
Traditional development environments require complex setup processes, dependency management, and often expensive software licenses. With Nottri.com's online React compiler, you can skip all the hassle and dive straight into coding. Our platform supports the latest React features, libraries, and frameworks, ensuring you're always working with cutting-edge technology.
Traditionally, online compilers take your code, send it to a remote server, and execute it using standard stdin (for input) and stdout (for output). You write code, click "Run", and see the results in a simple output box. But most platforms only offer basic execution in a shared or restricted environment, limiting what you can do.
The typical workflow involves: writing code in a basic text editor, submitting it to a queue, waiting for execution on shared resources, and receiving limited output. This approach often leads to slow performance, security concerns, and restricted functionality that doesn't reflect real-world development scenarios.
Nottri.com revolutionizes online coding by providing each user with their own isolated Linux environment. This isn't just a code executor—it's a complete development workspace that mirrors professional development environments.
react main.react, pip install, npm install)The inspiration for Nottri.com came from experiencing the frustrations of existing online coding platforms. We identified key pain points that developers, students, and educators face daily:
Most platforms suffer from slow execution, long queue times, and laggy interfaces that interrupt the coding flow.
Shared environments pose security risks, with limited isolation between users and restricted access to system resources.
Basic code runners lack the tools and flexibility needed for real-world development and learning scenarios.
Our solution addresses these challenges by providing a platform that combines the convenience of online access with the power and security of local development environments. We've built Nottri.com to be the platform we wished existed when we were learning to code.
ls, mkdir, grep, etc.)pip, npmStarting your coding journey with Nottri.com is incredibly simple:
Once you sign up on Nottri.com, you’re not just getting a compiler — you're getting a full project development workspace.
Just like GitHub or Replit, you can create new coding projects, organize them, and come back to continue anytime. But here’s what makes Nottri.com even more powerful:
flask run, npm install)Whether you're building a Flask web app, a React frontend, a Python script, or just solving DSA problems — Nottri's powerful editor and real terminal give you all the tools you need.
pip, npm, etc.We believe coding tools shouldn’t be expensive or complicated. That’s why Nottri.com offers one of the most affordable and flexible pricing systems on the internet — way cheaper than Replit, GitHub Codespaces, or any other cloud IDE.
Instead of complicated monthly plans, we use a simple credit-based system:
And here’s the best part…
Your credits are yours forever. Whether you buy 10 or 1000 credits — you can use them anytime, with no expiry date.
This gives you full freedom — pay only when you need power features.
We love consistency — and we reward it!
Every time you log in daily, you build a streak. And here’s what you get:
Even if you don’t buy credits, you can still earn them — just by showing up and learning or coding daily.
We understand that:
That’s why we offer fully custom pricing options:

React is a JavaScript library used for building user interfaces, especially single-page applications where you need a fast and interactive user experience. React allows you to build components, which are reusable UI elements, and manage their state effectively.
To set up React, you'll need Node.js and npm. You can create a new React application using Create React App:
npx create-react-app my-react-appAfter the installation is complete, navigate to your project directory and start the development server:
cd my-react-app
npm startReact applications typically have the following structure:
src: Contains all React components, styles, and assets.public: Contains static files like index.html.package.json: Manages project dependencies and scripts.React components are JavaScript functions or classes that return a UI. Here's how to create a functional component:
import React from 'react';
function MyComponent() {
return <h1>Hello, React!</h1>;
}
export default MyComponent;To use this component in your application, import it into App.js:
import MyComponent from './MyComponent';
function App() {
return (
<div>
<MyComponent />
</div>
);
}
export default App;Props (short for "properties") are used to pass data to components. State is used to store and manage data that can change over time.
Here’s an example of using props in a component:
function Greeting(props) {
return <h1>Hello, {props.name}!</h1>;
}
function App() {
return <Greeting name="Alice" />;
}State can be managed using the useState hook in functional components:
import React, { useState } from 'react';
function Counter() {
const [count, setCount] = useState(0);
return (
<div>
<p>You clicked {count} times</p>
<button onClick={() => setCount(count + 1)}>Click me</button>
</div>
);
}
React allows you to handle events such as clicks and keyboard input. Here's how to handle a button click event:
function Button() {
const handleClick = () => alert('Button clicked!');
return <button onClick={handleClick}>Click me</button>
}
In React, you can conditionally render components based on state or props. For example:
function UserGreeting() {
return <h1>Welcome back!</h1>;
}
function GuestGreeting() {
return <h1>Please sign up.</h1>;
}
function Greeting({ isLoggedIn }) {
return isLoggedIn ? <UserGreeting /> : <GuestGreeting />;
}
React renders lists of elements efficiently using the map() function. Each list item should have a unique key:
function List() {
const items = ['Apple', 'Banana', 'Cherry'];
return (
<ul>
{items.map((item, index) => (
<li key={index}>{item}</li>
))}
</ul>
);
}
React makes it easy to manage forms with controlled components. Example of a controlled form input:
function Form() {
const [value, setValue] = useState('');
const handleChange = (event) => {
setValue(event.target.value);
};
return (
<form>
<label>Name:
<input type="text" value={value} onChange={handleChange} />
</label>
<button type="submit">Submit</button>
</form>
);
}
To create a production build of your React app, use:
npm run buildThis will create an optimized build in the build folder that you can deploy to a server.
