// Core capabilities

Browser-native IDE.
Zero configuration needed.

Unified Dashboard

Manage all your projects, cloud environments, and billing from a single centralized dashboard. Clone GitHub repositories with one click and organize your work seamlessly.

Instant Mode (WebContainers)

Boot fully-featured Node.js environments directly in your browser in milliseconds. Perfect for instant prototyping, interactive tutorials, and frontend frameworks—all with zero backend infrastructure.

Cloud Mode (VS Code Server)

Need more power? Spin up dedicated Docker containers running VS Code Server orchestrated by Kubernetes. Access real databases, heavy backend frameworks, and enterprise-grade compute.

// Use cases

One platform. Every use case.

Instant Mode

Rapid Prototyping

Got an idea? Boot a full Next.js or React environment in milliseconds. WebContainers run entirely in the browser, meaning you can start coding and previewing without waiting for a server to provision.

server.ts

1import { createServer } from 'http';
2
3const server = createServer((req, res) => {
4  res.writeHead(200, { 'Content-Type': 'text/plain' });
5  res.end('Hello from WebContainers!\n');
6});
7
8// This server runs entirely in your browser tab
9server.listen(3000, () => {
10  console.log('Server is running at http://localhost:3000/');
11});

Cloud Mode

Heavy-duty Backends

Building complex systems? Cloud mode provisions an isolated Docker container with VS Code Server, giving you the power to run Postgres, Redis, and massive monorepos just like your local machine.

database.ts

1import { Client } from 'pg';
2import { createClient } from 'redis';
3
4// Connect to databases running alongside your code
5const pgClient = new Client(process.env.DATABASE_URL);
6const redisClient = createClient({ url: process.env.REDIS_URL });
7
8await pgClient.connect();
9await redisClient.connect();
10
11console.log('Connected to Enterprise infrastructure.');

Share instantly

Live Previews

Share a live preview of your running application with your team or clients instantly. Every workspace gets a secure, publicly accessible URL that updates in real-time as you code.

app.ts

1// Every workspace exposes a secure URL instantly
2import express from 'express';
3const app = express();
4
5app.get('/', (req, res) => {
6  res.send('Hello World! This is live on the internet.');
7});
8
9// Port 3000 is automatically proxied to a public URL
10app.listen(3000, () => {
11  console.log('Live at: https://workspace-xyz.websandbox.com');
12});

// Benefits

Boot instantly. Scale infinitely.

Instant Boot Times

WebContainers boot in milliseconds, giving you an immediate browser-native environment.

Cloud Mode Capabilities

Spin up dedicated VS Code Server containers for heavy-duty full-stack development.

Enterprise Isolation

Fully isolated Docker containers orchestrated by Kubernetes for absolute security.

Seamless Previews

Dynamic subdomain proxying gives you instant, secure preview URLs for your apps.

Browser-Native Terminal

Execute real bash commands and run Node.js scripts exactly like your local machine.

Zero Setup Required

No more 'it works on my machine'. Share environments instantly with your team.

// Testimonials

Loved by developers. Built for productivity.

WebSandbox cut my development time in half. The instant WebContainers boot before I even have time to blink. No more 'npm install' on my local machine.

Sarah ChenSenior Engineer

Zero setup, instant productivity. I switched from CodeSandbox and never looked back. The dual modes are exactly what our team needed.

Get the exact environment you need with zero configuration. My productivity has skyrocketed.

Finally, a cloud IDE that doesn't feel like a toy. Connecting to a real Kubernetes-orchestrated VS Code Server gives me full terminal access and absolute isolation.

Best cloud environment I've ever used. It's like WebSandbox reads my mind—instant previews, fast boots, and zero local overhead. Plus, the Docker isolation gives me peace of mind.

Ethan RDevops

No more wading through broken local environments and conflicting dependencies.

I was skeptical about browser IDEs until WebSandbox. The precision is unmatched—it runs my heavy Next.js and Postgres stacks in the cloud without breaking a sweat.

Emma LarssonFull-stack Developer

WebSandbox eliminated the back-and-forth I had with other cloud platforms. Click once, get an isolated Docker container with dynamic port proxying. Game changer.

The enterprise-grade security approach gives me peace of mind.
