It sends your code to a secure cloud-based execution engine (Judge0) that compiles and runs it in an isolated sandbox, then returns the output instantly.

No. Your code is sent directly to the execution engine for processing and is never stored, logged, or monitored by us.

This tool is ideal for learning, prototyping, and quick testing. For production development, we recommend using a full IDE with debugging capabilities.

The execution engine enforces a strict time limit. If your code exceeds it, the process is automatically terminated and you will see a 'Time Limit Exceeded' error.

Yes, each execution is sandboxed with a memory limit to prevent abuse. For most programs, this limit is more than sufficient.
