CodeSandbox is a cloud-based development platform that provides instant, collaborative online IDEs and scalable VM sandboxes for rapid web development, prototyping, AI code execution, and team collaboration.

---

🚀 Overview

CodeSandbox is an innovative cloud development platform that delivers instant development environments, allowing users to code, collaborate, and ship projects from any device without local setup. It offers both lightweight Browser Sandboxes for quick prototyping and powerful VM Sandboxes for full-scale applications, supporting a wide range of frameworks and languages.

This project solves the problems of time-consuming environment setup, dependency hell, and insecure code execution by providing isolated, secure sandboxes that spin up in seconds. It's built for developers prototyping ideas, teams needing real-time collaboration, students learning modern web tech, and AI builders requiring safe, scalable code interpretation.

The platform was created to make web development faster, more accessible, and device-agnostic, evolving from a simple online editor to a robust cloud infra solution now powered by Together AI.
