How to use

Write JavaScript code in the editor panel, click Run to execute it in a secure sandbox. Console.log output, return values, and errors are displayed in the output panel. All execution happens locally in your browser.

  • VS Code-style syntax highlighting with autocompletion
  • Secure sandboxed execution — code cannot access your page
  • Real-time console.log output capture
  • Everything runs in your browser — no server involved
