Code Editor

This tool provides a multi-language code editor with an integrated sandboxed runner to enable rapid coding experiments and snippet validation. It accepts a language, code input, and optional stdin, then executes the code in a secure environment and returns outputs. Conceptually, the editor decouples editing from execution, allowing users to iteratively refine logic and compare results across attempts. By isolating runs, it prevents side effects on the host page and supports deterministic testing. The primary beneficiaries are learners practicing problems, instructors validating submissions, and engineers testing small algorithms or API usage. Unique value lies in immediate, reproducible results, robust error reporting, and lightweight portability for embedding in tool pages. Core features include language selection, code input, optional stdin, execution timeouts, memory controls, and result capture (stdout, stderr, exit code). Advanced options may add multi-file support, templates, and run history for comparisons. Use cases range from debugging algorithms in Python or JavaScript to validating snippets in C/C++ during code reviews or teaching sessions.
