About This Tool

Code Run Tool provides a sandboxed environment to compile and run code snippets in multiple languages. It captures standard output and errors, isolates execution, and returns structured results including exit codes and timing metrics. Conceptually, the tool maps each language to a lightweight runtime container or interpreter, enforces resource limits, and streams results back to the requester. Benefits include developers who want quick feedback during prototyping, educators who demonstrate concepts safely, and technical writers who include runnable examples in documentation. Unique value lies in reproducible environments, language-agnostic I/O capture, and straightforward result formatting that supports automation and reporting. Core features include language selection, input data handling, stdout/stderr capture, resource limiting, and exportable results; optional features cover stdin data, multiple files, and execution logs. Use cases span algorithm testing, API mock demonstrations, and teaching loops that require deterministic behavior across languages.

How to Use

Provide inputs: paste code and select language.
Provide optional stdin and resource constraints.
Run code: execute the sandboxed runner.
Review outputs: inspect stdout, stderr, exit code, and timing.
Iterate: modify code and re-run as needed.

Frequently Asked Questions

Find Quick Answers

What languages are supported?
The tool supports a broad set of popular languages including Python, JavaScript, Java, C/C++, Go, and Rust, each executed in isolated sandboxes. Compiled languages undergo a compile step before execution. Outputs include stdout, stderr, and a runtime metric. Network access is disabled by default to maintain reproducibility and safety.
Is the execution isolated from my environment?
Yes. Each run executes in a sandboxed environment with strict resource limits and no access to the host file system or network unless explicitly permitted. This isolation prevents cross-session leakage and protects the host system while ensuring consistent results.
Can I provide input data to the program?
Yes. The tool supports providing stdin data as an input stream and optional file-based inputs. This enables testing of programs that require input from standard input or file I/O, with outputs captured for verification.
Are results stored for later reference?
Runs are ephemeral by default. Outputs, metadata, and logs are returned to the caller for integration with automation, but are not retained long-term unless explicitly configured in a managed workspace or export workflow.
