# Devbox prices: 4 vCPU / 8 GB

11 providers: one busy 1-hour session at 4 vCPU / 8 GB costs ≥ $0.034 (InstaBox) to $0.634 (Runloop).

1 h busy: all CPU billed. 1 h at 10% CPU: lower only where idle CPU isn't billed. Fleet month: 50 × 8 h × 22 days, busy, plus any plan minimum. Fixed sizes use the smallest size that fits. "≥" means a billing term is not published. Method: https://roost.guide/methodology/
