A card-free trial
Get a one-time $5 runtime credit for 30 days without a card. The trial allows one retained Micro sandbox. Top up during the trial to unlock other sizes; unused trial credit still lasts until its original deadline.
Prepaid runtime
Add any amount above $2 as you need it. Running time draws from your balance, and sandboxes stop when it is too low. The paid offer allows up to 10 running sandboxes, subject to host capacity. Stopped root disks are retained free for 30 days.
