Online IDE Using Cloud Containers
Why Choose This Project?
An Online IDE allows users to write, run, and test code directly in their browser—without needing to install compilers or SDKs locally. By using cloud containers, each user session runs in an isolated and secure environment, ensuring scalability, performance, and safety.
Ideal for students, interview platforms, competitive coding portals, or enterprise code collaboration tools.

Execution Flow
-
User signs in → opens the IDE
-
Enters code, selects language, and clicks Run
-
Backend API spins a Docker container with preinstalled compilers
-
The code is executed inside the container, output captured
-
Output is sent back to frontend and shown in the terminal
-
After timeout or execution, the container is stopped/cleaned
