Real Code Execution

Submit code in JavaScript or C++ and see it run against hidden test cases in a sandboxed environment.

Async Evaluation

Submissions are queued through a dedicated async worker and processed in isolation — no blocking the HTTP thread.

Instant Feedback

Per-test-case results with stdout, expected vs actual output, and pass/fail status.
