PayPal sandbox. Test money only.PayPal sandbox. Test money only.

PayPal sandbox. Every order, hold, capture and refund here uses PayPal sandbox test money.

Try a rescue · about 7 minutes, you act for about 2

No hold, no keystrokes.
Only your server answering can charge you.

An AI fixes a dead server through its console. It gets the keyboard only while a PayPal hold is live, and you are charged only if your own check of the server passes. The VM boots in 5 to 30 seconds, then Claude takes a free look.

Every rescue, five steps

Passcode

Runs use a real test VM and a paid model, so /try is behind a passcode. It is in the submission's testing instructions, together with a one-click judge link.

No passcode? Every earlier run is in the ledger, or open a finished one:
