A full development environment that runs in your browser. Fork, prototype, and deploy without local setup.
CodeSandbox gives you a containerized dev environment in the cloud — React, Vue, Node, Next.js, and 50+ templates boot instantly. Share a URL and your collaborator gets the exact same setup. No 'works on my machine' ever again.
Who it's for: Front-end developers, educators, and teams who prototype constantly and want zero-config environments that live in the cloud.
Pick a template or import a GitHub repo and your environment is ready in seconds — no npm install locally.
Pair-program with live cursors and shared terminals, like Google Docs for code.
Need a backend? Devboxes give you a real Linux container with terminals, tasks, and ports.
Push to a live URL or connect to your CI. Previews regenerate on every commit.
For prototyping, teaching, and quick forks, CodeSandbox is unbeatable in 2026. Pair it with Cursor or your local IDE for deep work; use Sandbox for shareable, instant environments.
