a code execution engine, provides a web based interface to write, compile and run code in multiple programming languages (Python 3, JavaScript / TypeScript, C / C++, Java, Go, PHP, Rust)

tech stack

• backend: rust (using std::net::TcpListener for networking and std::process::Command for execution)
• frontend: html, vanilla js and css
• networking: custom http server implementation over tcp

architecture

it consists of a rust based server that:

1. binds to a TCP port and listens for incoming requests
2. serves a web interface for code editing
3. receives code via POST requests, executes it using the relevant system compiler/interpreter and returns the output to the frontend
