Run AI-written code without risking your own systems.

Litterbox runs untrusted code in a sealed box that cannot reach your network or your keys, returns the result, and deletes the box.

Without Litterbox

  • AI-written code runs on machines that hold your secrets
  • One bad command can delete data or leak a key
  • Building your own sandbox takes months

With Litterbox

  • Every run is sealed off and thrown away
  • One API call, no servers to manage
  • Every run recorded, so failures can be replayed

How it works

Three steps. That is all.

  1. Send

    Your app sends the code and any files it needs

  2. Run

    It runs sealed: no network, 60 seconds, capped memory

  3. Return

    You get the output back and the sandbox is destroyed
