Code Sandbox

Browser-based coding environment for missions and workshops.

Overview

The sandbox is a browser-based code editor with a live execution environment. You write, run, and test code directly in the browser without needing any local setup.

Features

  • Syntax highlighting and code completion
  • Python and JavaScript/TypeScript runtimes
  • Real-time output panel
  • Automated validation against acceptance criteria
  • Hint system with progressive reveals
  • Solution submission and XP tracking

Tips

💡Read the acceptance criteria carefully before coding. The validation engine checks specific outputs and behaviors, so understanding the requirements upfront saves time.
