How does CodeLab isolate execution?

CodeLab runs each submission in an isolated, sandboxed environment to ensure your code executes safely and independently. This prevents your work from interacting with other users, accessing external systems, or affecting any part of the HuntCode platform.

Secure, Isolated Execution

Every CodeLab submission is processed inside a tightly controlled runtime with strict limits on what the code can access. This sandboxing ensures your code can’t reach the network, modify files, or interact with anything outside the challenge itself.

• Sandboxed runtime: Code executes in a confined environment separate from other users.
• No external access: Submissions cannot make network requests or connect to any outside systems.
• Restricted behavior: Only the functions required for the challenge are allowed.
• Consistent results: Every user gets the same controlled execution environment.

Why isolation matters

Isolating execution keeps CodeLab safe, predictable, and fair. It ensures that challenges behave consistently and that your submissions can only influence the specific task you’re working on—not the browser, the platform, or external systems.

As CodeLab expands, additional safeguards and runtime enhancements will be added to support more advanced scenarios while maintaining secure isolation.
